Has a lift pump good batteries, crank cam sensors are good, ficm is good, and ecm is good.18 October 2017 09:16
was driving, did hear some knocking but was not constant with the rpm. have been having heating issues (had a water pump and other things ship in that morning) the temp started to rise to 240 so went to pull over and the truck just shut off. did not want to crank very fast after it cooled down. got it towed back home. checked the codes and got a p0374 code. well checked the cam and crank reluctor wheels no play. pulled glow plugs checked compression a 300 avg with a gauge that reads less than normal. (one glow plug broke off in the head, drilled it out and tapped but is leaking air slightly after i put the new ones in) im going to have to figure that one out, even step drilling it it still isnt 100% centered. anyway put all new glow plugs in and straps. turned over by hand no play in the crank. used a buddies truck and put my crank, cam, ficm, ecm, and tcm on his truck and is started no issue. so im left with wiring and injectors? i do have some frayed wires but only on a ground wire. i ohm the plugs. i am getting 45kohms out of the cam sensor plug on the cam signal wire. but only when the harness is plugged into the ecm. is this normal? i am getting .12 amps out of the ground wire on both the cam and crank sensor plugs. again is this normal? or should i be pulling the harness and looking for more of a short to ground? i have not gotten this code after i have cleared it. only one that keeps showing up is p0700 a trans code. but doubt thats my cause for no start. also would like to note that if i try to hold the key cranking it over it will start to crank slower and slower until it doesnt crank over any more.batteries have been tested (and are fairly new), i ended up braking the starter so have a brand new one to put on it now but the old one did test good but a bolt fell out of it and cracked the starter housing with one bolt. lol

That's what I wasn't sure about. A scanner is only as good as the user and I never used a tech 2. Borrowed it from a friend for a few hours. So I am not sure. Any other way to test that with out a scanner?

    Parts Information

    Parts required to complete this special policy are to be obtained from General Motors Service Parts Operations (GMSPO).

    *P/N 97729095 is only available in a merchandising pack quantity of 4.

    It is recommended that the customer purchase the latest released fuel filter, P/N 12633243. Refer to Corporate Bulletin Number 04-06-04-070B.

    Customer Notification

    Customers will be notified of the special policy on their vehicles by General Motors (see copy of typical customer letter shown in this bulletin - actual divisional letter may vary slightly).

    Injector Core Return Process - Effective June 2008

    Effective June 2008, the handling of 6.6L Duramax Injector (MY01-MY04 LB7) cores for part number 97729095 changed. The majority of injector cores will now be returned using the normal light core return process to UPS-Supply Chain Solutions (UPS-SCS). For these cores, credit will be issued using the normal GMSPO core credit process. However, a sampling of injectors replaced under warranty will continue to be returned to the Warranty Parts Center (WPC) for evaluation. This dual process will simplify the core credit process for dealers and provide more efficient handling of the cores overall.

    For injector warranty claims, dealers should continue to hold cores until the warranty claim is paid.

    Important
    All replaced injectors must be returned to either the WPC or the core return center (UPS-SCS). Approximately 30% of the warranty claims will be requested back to the WPC.

    Important
    WAIT UNTIL THE WARRANTY CLAIM IS PAID TO DETERMINE THE LOCATION TO WHICH THE INJECTORS MUST BE RETURNED. IF A WPC PART RETURN REQUEST IS RECEIVED, RETURN THE INJECTORS TO THE WPC. IF A WPC PART RETURN REQUEST IS NOT RECEIVED, THEN RETURN THE INJECTORS TO THE CORE RETURN CENTER. Please follow Corporate Bulletin 99-00-89-019E that applies to the WPC return procedures. All injectors of a single engine must arrive at the WPC boxed or bagged together in sets of four or eight injectors. A copy of the part request, repair order with technician comments, snapshot of the preliminary (actual) fuel rail pressure vs. desired as commanded by the Tech 2(R) to 160 MPa, and the completed diagnostic worksheet must be included with the injectors. No snapshot is required for vehicles that do not start. If the WPC does NOT request the injectors, return the cores following the normal light core guidelines (apply through EPIC/RAPID)* to UPS-Supply Chain Solutions (UPS-SCS)*.* In Canada, injector cores are now to be returned using the normal core return process using form PC659C (Application for Authorization to Return Material) unless requested by the WPC. Sets of injectors should be secured with tape or in an overpack container in sets of four or eight for returns to both UPS-SCS and to the WPC. A copy of the repair order and diagnostic worksheet is still requested with the core for both warranty related and regular return.

    For returns to UPS-SCS, the core ID label (2) must be visible on the outside end of the package at the opposite end from the part label (1).

    Claim Information

    1. Submit a claim using the table below.

    2. Courtesy Transportation:

    -If using GWM, submit as a Net Item under the appropriate labor code.

    -If using WINS, submit using normal labor operations for courtesy transportation as indicated in the GM Service Policies and Procedures Manual.

    Important
    A copy of the completed diagnostic worksheet and other required documentation (e.g. Tech 2(R) snapshots) MUST BE INCLUDED in the box with the returned injectors.

    * The amount identified in "Net Item" should represent the actual dollar amount for shop supplies needed to perform the required repairs.

    ** The amount identified in "Net Item" should represent the dollar amount reimbursed to the customer.

    Customer Reimbursement - For US

    All customer requests for reimbursement for previous repairs for the special policy condition will be handled by the Customer Assistance Center, not by dealers.

    A General Motors Special Policy Customer Reimbursement Procedure form is shown in this bulletin.

    Important
    Refer to the GM Service Policies and Procedures Manual, section 6.1.12, for specific procedures regarding customer reimbursement and the form.

    Customer Reimbursement - Canada

    Customer requests for reimbursement for previous repairs to correct high fuel return rate by replacing fuel injectors in 2004 model year trucks are to be submitted prior to or by November 30, 2008. Repairs must have occurred within the 7 years of the date the vehicle was originally placed in service, or 320,000 km, whichever occurs first.

    When a customer requests reimbursement, they must provide the following:

    -Proof of ownership at time of repair.

    -Original paid receipt confirming the amount of unreimbursed repair expense(s) (including Service Contract deductibles), a description of the repair, and the person or entity performing the repair.

    If the work was done by someone other than a GM dealership, the amount of reimbursement will be limited to the amount that the repair would have cost GM to have it completed by a GM dealership.

    po 374 crank sensor related commun ication issue

    Ask Your Own Chevy Question
    Chevy Mechanic: eric remington,
     replied 8 months ago

    CIRCUIT DESCRIPTION
    The engine control module (ECM) replicates the signal received from the crankshaft position (CKP) sensor. This signal is sent to the fuel injection control module (FICM) through the engine speed signal circuit. The FICM uses this replicated signal to generate injection current and control the recharge of the fuel injection high voltage circuits. When cranking, the FICM has full control of the fuel injectors. The only input the FICM uses at this time is the engine speed signal from the ECM. The FICM monitors the signal along with the injection request signals from the ECM after the engine is running. If there is a problem with this signal, a DTC could set.

    CONDITIONS FOR RUNNING THE DTC
    The engine is cranking or running.

    CONDITIONS FOR SETTING THE DTC
    The FICM does not receive a crank signal, but does receive injection requests from the ECM.

    OR

    The FICM receives an invalid crank signal from the ECM.

    ACTION TAKEN WHEN THE DTC SETS

    • The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails.
    • The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.

    CONDITIONS FOR CLEARING THE MIL/DTC

    • The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
    • A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
    • A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
    • Clear the MIL and the DTC with a scan tool.

    DIAGNOSTIC AIDS
    A missing high resolution signal will cause a no-start condition.

    TEST

    Steps 1-2

    Steps 3-7

    Steps 8-12

    It has not came back at all the last 15-20 times I cranked it. Only code I have gotten was a generic p0700 tranny code. But dnt have a scanner to read the tcm. When I have someone here to crank the truck I will check for the reference wire voltage to the ficm. In the mean time i will have to check everything else and put the starter back in.Is there an ohm spec on the injectors it's self or the harness?
    Customer reply replied 8 months ago
    I did get missed pulses from the crank and cam sensor on the tech 2. So this is why I have been trying everything I can with the wiring. The crank and can both get a 12v and a ground. But is there and ohm reading on the reference wire? Also the ground wire for both crank and can have .12 amp draw with the key on.
    Customer reply replied 8 months ago
    What should the volts be coming from the injector harness? Where my readings accurate or?
    Customer reply replied 8 months ago
    Also do you have a pin out for the ficm? I can probably find the reference wire pin by testing for continuity, but that would make my life a little easier haha

      13421 - FUEL TRANSFER PUMP RECALL

      SERVICE CAMPAIGN BULLETIN

      Reference Number(s): 13421, Date of Issue:

      Affected Model(s):Various Serviced Vehicles Equipped with 6.6L Diesel Engine (LML/LGH) and Dual Fuel Tanks (N2N)

      SERVICE INFORMATION

      Fuel transfer pumps involved in this recall were used to service various serviced vehicles, equipped with a 6.6L diesel engine (LML/LGH) and dual fuel tanks (N2N). Dealers who ordered this part for service are identified in the attachment contained in the Administrative Message (U.S.) or Dealer Communication (Canada). Please see the Vehicles Involved section for details.

      CONDITION

      General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain fuel transfer pumps used in service for various vehicles, equipped with a 6.6L diesel engine (LML/LGH) and dual fuel tanks (N2N). The transfer pump, which moves fuel from the rear tank to the front tank, may malfunction. This malfunction could cause the fuel gauge to indicate an inaccurate reading, illuminate the Service Engine Soon lamp, reduce engine power, prevent the vehicle from starting, or cause the vehicle to stall. If the vehicle stalls, it could increase the risk of a crash.

      CORRECTION

      Dealers are to inspect the manufacture date of the fuel transfer pump and, if necessary, replace the fuel transfer pump.

      VEHICLES INVOLVED

      Various serviced models may have had a suspect part installed during a service visit. A search of General Motors sales records has identified the following 3 categories of sales:

    • Sales records that contain a VIN . These identified VINs will be on the Investigate Vehicle History (IVH) screen in GM Global Warranty Management (GWM) system. GM will contact these customers.
    • Sales records that contain a customer address but no VIN . GM will contact these customers. The VIN will not appear in IVH.
    • Sales records that do not contain a VIN or customer address . Attached to the dealer message announcing this recall is a list that identifies the involved dealers and provides an invoice number. Dealers are to search their part sales records to determine the name and address of the purchaser. If the purchaser is the owner of the vehicle, dealers are to send the owner a copy of the letter found in this bulletin, requesting that their vehicle be brought in for repair. If the purchaser is a body shop, independent repair shop, etc., dealers are to contact the repair facility and obtain the owner's name and address and send the owner a copy of the letter. The VIN will not appear in IVH.
    • For dealers with involved vehicles that can be identified by VIN, a listing with involved vehicles containing the complete VIN, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.

      The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.

      PARTS INFORMATION

      Parts required to complete this recall are to be obtained from General Motors Customer Care and Aftersales (GMCC&A). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.

      Part Number Description Quantity/Vehicle

      23484681PUMP, FUEL (ELEC)1 (if req'd)

      22514722SEAL, FUEL FEED PIPE(O RING) (merch pkg of 10)2 (if req'd)

      SERVICE PROCEDURE

    • Remove the fuel transfer pump. Refer to Fuel Pump Replacement (Auxiliary Tank, Balance) in SI.
    • Determine the fuel transfer pump date code. Locate the 4 digit date code number (2) that is below the part number (1). Replace any fuel transfer pumps with the following date code numbers: 0612 - 3662 or 0013 - 1213. The first three numbers are the Julian date of the year and the last number is ***** year. Example: 0612 = 3/1/12.

      NOTE:

      There are two O-rings - one on each of the fuel lines that connect to the pump. The fuel line O-rings may be re-used if they are NOT damaged. Inspect the fuel line O-rings for damage or contamination. Replace the O-rings as necessary.

    • Install the new or inspected OK fuel transfer pump. Refer to Fuel Pump Replacement (Auxiliary Tank, Balance) in SI.

    • RECALL IDENTIFICATION LABEL - CALIFORNIA, CONNECTICUT, DELAWARE, MARYLAND, MASSACHUSETTS, MAINE, OREGON, VERMONT, WASHINGTON VEHICLES ONLY

      Place a Recall Identification Label on each vehicle corrected in accordance with the instructions outlined in this Product Recall Bulletin.

      CUSTOMER REIMBURSEMENT - FOR US

      Customer requests for reimbursement of previously paid repairs for the recall condition are to be submitted to the dealer by June 30, 2015, unless otherwise specified by state law. If this is not convenient for the customer, they may mail the completed Customer Reimbursement Request Form and all required documents to the GM Customer Assistance Center.

      All reasonable and customary costs to correct the condition described in this bulletin should be considered for reimbursement. Any questions or concerns should be reviewed with your GM representative prior to processing the request.

      When a customer requests reimbursement, they must provide the following:

    • A completed Customer Reimbursement Request Form. This form is mailed to the customer or can be obtained through GM GlobalConnect.
    • The name and address of the person who paid for the repair.
    • Paid receipt confirming the amount of the repair expense, a description of the repair, and the person or entity performing the repair.
    • IMPORTANT:

      GM requires dealers to approve or deny a reimbursement request within 30 days of receipt. If a reimbursement request is approved, the dealer should immediately issue a check to the customer and submit an appropriate warranty transaction for the incurred expense. If a reimbursement request is denied, the dealer MUST provide the customer with a clear and concise explanation, in writing, as to why the request was denied. The bottom portion of the Customer Reimbursement Request Form may be used for this purpose. If the denial was due to missing documents, the customer can resubmit the request when the missing documents are obtained, as long as it is still within the allowed reimbursement period.

      Warranty transactions for customer reimbursement of previously paid repairs are to be submitted as required by GM Global Warranty Management. Additional information can also be found in Warranty Administration Bulletin 11-00-89-004.

      CUSTOMER REIMBURSEMENT - FOR CANADA AND EXPORT

    • Proof of ownership at time of repair.

    • All reasonable and customary costs to correct the condition described in this bulletin should be considered for reimbursement. Any questions or concerns should be reviewed with your GM representative prior to processing the request.

      COURTESY TRANSPORTATION - FOR US AND CANADA

      The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.

      CUSTOMER NOTIFICATION - FOR US AND CANADA

      General Motors will notify identified customers of this recall on their vehicle (see copy of customer letter included with this bulletin). Dealers that have been identified as having over-the-counter sales are to inspect their sales records to determine the purchaser of the involved part. After determining the name and address of the purchaser, dealers are to send each owner a copy of the owner letter requesting that their vehicle be brought in for this recall.

      CUSTOMER NOTIFICATION - FOR EXPORT

      Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter. Dealers that have been identified as having over-the-counter sales are to inspect their sales records to determine the purchaser of the involved part. After determining the name and address of the purchaser, dealers are to send each owner a copy of the owner letter requesting that their vehicle be brought in for this recall.

      DEALER RECALL RESPONSIBILITY - FOR US AND EXPORT (US STATES, TERRITORIES, AND POSSESSIONS)

      It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.

      The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.

      DEALER RECALL RESPONSIBILITY - ALL

      Dealers who have ordered the recalled part for service are identified in the attachment contained in the dealer message announcing this recall. Dealers who have received this listing are required to inspect their sales records to determine the name and address of the purchaser of the recalled part.

      If the purchaser is the owner of the vehicle, dealers are to send the owner a copy of the customer letter requesting that their vehicle be brought in for this recall.

      If the purchaser is NOT the owner of the vehicle, i.e., body shop, independent repair shop, etc., dealers are to contact the repair facility and obtain the customer's name and address so a copy of the customer letter can be sent to these customer.

      Since General Motors Customer Care and Aftersales records do not always contain customer names and addresses for these over-the-counter sales, it is important that each involved dealer take the necessary time required to responsibly identify customers who have purchased the recall part.

      All vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles.

      Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

      In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

      OWNER LETTER

      Dear General Motors Customer:

      This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

      General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain fuel transfer pumps used in service for various vehicles, equipped with a 6.6L diesel engine and dual fuel tanks. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.

      IMPORTANT:

    • Your vehicle is involved in GM safety recall 13421.
    • Schedule an appointment with your Chevrolet or GMC dealer.
    • This service will be performed for you at no charge .
    • Why is your vehicle being recalled? Our records indicate that your vehicle may have been serviced with, or you may have purchased, a recalled fuel transfer pump. The fuel transfer pump, which moves fuel from the rear tank to the front tank, may malfunction. This malfunction could cause the fuel gauge to indicate an inaccurate reading, illuminate the Service Engine Soon lamp, reduce engine power, prevent the vehicle from starting, or cause the vehicle to stall. If the vehicle stalls, it could increase the risk of a crash.

      What will we do? Your Chevrolet or GMC dealer will inspect the manufacture date of the fuel transfer pump and, if necessary, replace the pump. This service will be performed for you at no charge . Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual inspection and, if necessary, replacement time of approximately 30 minutes.

      What should you do? You should contact your dealer to arrange a service appointment as soon as possible.

      Did you already pay for this repair? Even though you may have already had this condition corrected, you will still need to take your vehicle to your dealer for an inspection. If you have paid for repairs for the recall condition, please complete the enclosed reimbursement form and present it to your dealer with all required documents. Working with your dealer will expedite your request, however, if this is not convenient, you may mail the completed reimbursement form and all required documents to Reimbursement Department, PO Box 33170, Detroit, MI###-##-#### The completed form and required documents must be presented to your dealer or received by the Reimbursement Department by June 30, 2015, unless state law specifies a longer reimbursement period.

      Do you have questions? If you have questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer Assistance Center at the number listed below.
