what have you done so far ?
Customer: replied 5 years ago.
just bought truck today had serviced changed air and fuel filter. Was having trouble with this problem before had truck serviced. truck feels like it's flooded. Just cranks and cranks and finally starts after about 10 seconds
Expert:  fordman312009 replied 5 years ago.
you need to have the codes scanned on the pcm and then give me the codes ok and we can get it done
Customer: replied 5 years ago.
I need to go to a dealership to scan codes right?
Expert:  Ray M. replied 5 years ago.

Yes you will need to take it to a dealer for codes unless you know somone with a portable scantool. It sounds like you have what is a common problem with the 2005 to 2007 6.0l,the fiting on the high pressure oil pump has failed,this allows the high pressure oil to leak and causes a hard start no start condition. There is a TSB for this,I will send it so you can take it to your dealer for repair.

Publication Date: August 29, 2008

FORD:2005 Excursion
2005-2007 F-Super Duty
2005-2008 E-350, E-450

This article supersedes TSBs 08-9-9 and 05-12-3 to update the Service Procedure and Service Labor Times.

ISSUE:

Some 2005-2007 F-Super Duty, 2005-2008 E-Series and 2005 Excursion vehicles equipped with a 6.0L diesel engine may exhibit a hard start / long crank or no start condition due to low injection control pressure (ICP).

ACTION:

Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

NOTE:A FLOW CHART OF THIS PROCEDURE CAN BE FOUND AT THE END OF THIS ARTICLE. (FIGURES 13-16)

NOTE:THE LOW PRESSURE OIL SYSTEM MUST BE WORKING PROPERLY IN ORDER FOR THE HIGH PRESSURE OIL SYSTEM TO BUILD ICP PRESSURE. THIS INCLUDES ADEQUATE BASE ENGINE OIL SUPPLY PRESSURE AND GOOD QUALITY PROPERLY MAINTAINED OIL. THIS MUST BE VALIDATED BEFORE CONTINUING WITH THIS PROCEDURE.

  1. Install the Integrated Diagnostic System (IDS) scan tool, check ICP voltage key on engine off (KOEO) for bias: If voltage is not between 0.15 V and 0.35 V refer to Powertrain Controls/Emissions Diagnosis (PC/ED), and do not continue with this procedure.
  2. Check for diagnostic trouble codes (DTCs).
    1. If DTC P2623 is present go to pinpoint test R in PC/ED before continuing to the ICP Graph Comparison Test.
    2. If DTCs P2290 and/or P2291 are present proceed to the ICP Graph Comparison Test.
    3. If DTCs other than P2623, P2290 and/or P2291 are present refer to PC/ED, and do not continue with this procedure.
    4. If no DTCs are present proceed to the ICP Graph Comparison Test.

ICP Graph Comparison Test

NOTE:BATTERIES MUST BE FULLY CHARGED BEFORE PROCEEDING.

If oil is leaking from the ICP system or if air is trapped in the ICP system, the injection pressure regulator (IPR) valve may be commanded fully closed by the Powertrain control module (PCM) while the starter is engaged in an attempt to exceed 500 psi (3.5 MPa).

  1. Select the parameters indicated from the scan tool parameter list.
    1. ICP Pressure + Voltage.
    2. IPR Duty Cycle.
    3. Engine Speed (RPM).
  2. ICP pressure should reach 500 psi (3.5 MPa) within five (5) seconds of cranking engine. Normal crank time is 3-5 seconds.
    1. Normal start response for ICP, IPR Duty Cycle and Engine Speed - Operation shown. (Figure 1)


      Figure 1 - Article 08-18-6

    2. Hard start response for ICP, IPR Duty Cycle and Engine Speed - Operation shown. (Figure 2)


      Figure 2 - Article 08-18-6

    3. No start response for ICP, IPR Duty Cycle and Engine Speed - Operation shown. (Figure 3)


      Figure 3 - Article 08-18-6

  3. Compare the ICP PID data to the graph. (Figure 1)
    1. If the ICP PID data is within specification, (Figure 1), and the engine will not start, refer to PC/ED for no start diagnosis, and do not continue with this procedure.
    2. If the ICP PID data is within specification, (Figure 2 ) and the engine starts, drive the vehicle and monitor the engine oil temperature using IDS until the engine oil temperature (EOT) reaches 195 °F (91 °C). Proceed to Step 4.
    3. If the ICP PID data is not within specifications, (Figures 2 or 3), proceed to Step 5.
  4. With engine oil temperature (EOT) at 195 °F (91 °C). Crank the engine and recheck the ICP PID data.
    1. If repairs were performed and the ICP PID data is within specification, (Figure. 1), release the vehicle to the customer.
    2. If no repair has been made and the ICP PID data is within specification, (Figure. 1), refer to the PC/ED for intermittent diagnosis, and do not continue with this procedure.
    3. If the ICP PID data is not within specification and engine starts, (Figures 2 or 3), proceed to Step 6.
    4. If engine does not start, proceed to Air Pressure test ICP.
  5. Does the engine start?
    1. If the engine starts and the IPR has been replaced proceed to Step 7.
    2. If the IPR has not been replaced drive the vehicle and monitor the engine oil temperature using IDS until the EOT reaches 195 °F (91 °C). Turn off engine and proceed to Step 6.
    3. If the engine will not start, proceed to the Air Pressure Test (ICP) procedure. Refer to appropriate vehicle.
  6. If the engine starts with EOT at 195 °F (91 °C) perform a run up test by a slow neutral run up in park/neutral. Does the engine run rough between 3000 and 4000 RPM?
    1. If the engine runs rough replace the IPR valve. Proceed to Step 7.
    2. If the engine does not run rough, proceed to the Air Pressure Test (ICP) procedure.
    3. If the engine does not start, proceed to the Air Pressure Test (ICP) procedure.
  7. Start the engine and perform a run up test by a slow neutral run up in park/neutral. Does the engine run rough between 3000 and 4000 RPM?
    1. If the engine runs rough proceed to the Air Pressure Test (ICP) procedure.
    2. If the engine does not run rough crank the engine and recheck the ICP PID data.
      1. If the ICP PID data is within specification, (Figure 1), release the vehicle to the customer.
      2. If the ICP PID data is not within specification, (Figure 1), proceed to the Air Pressure Test (ICP) procedure.

Air Pressure Test ICP

NOTE:BEFORE PERFORMING THIS TEST, INSPECT THE O-RINGS OF THE TEST TOOLS. REPLACE IF WORN, CRACKED OR CUT.

NOTE:THE AIR PRESSURE APPLIED FOR THIS TEST MUST BE 100 PSI (689 kPa). WHEN AIR PRESSURE IS APPLIED FOR THE FIRST TIME, IT MAY TAKE 3 TO 5 MINUTES BEFORE THE LEAK CAN BE HEARD. THIS ALLOWS THE AIR PRESSURE TO DISPLACE THE ENGINE OIL IN THE ICP SYSTEM. ONCE THE ENGINE OIL IS DISPLACED, AN AIR LEAK CAN BE HEARD ALMOST IMMEDIATELY AFTER APPLYING AIR PRESSURE.

CAUTION:DO NOT LEAVE THE IPR VALVE ENERGIZED LONGER THAN 120 SECONDS. THIS CAN DAMAGE THE IPR VALVE

Econoline

  1. Remove the engine cover; refer to Work Shop Manual (WSM), Section 501-05.
  2. Remove M 12 plug from the top of the high-pressure oil pump. (Figure 4)

  3. Install test adapter 303-765 in the top of the high-pressure oil pump. Attach shop air hose to the test adapter. (Figure 4)
  4. Apply shop air at 100 psi (689 kPa) maximum to the high-pressure oil pump.
  5. Using IDS, command IPR open for two (2) minutes to clear the oil from the high pressure oil system.
  6. Using IDS close the IPR valve by increasing the IPR duty cycle. If no air noise change is heard, the IPR valve may not be functioning as commanded. If the IPR has been replaced proceed to Step 9. If the IPR has not been replaced in a previous repair install a new IPR valve and perform a slow neutral run up in park/neutral.
    1. If the engine will not start repeat the Air Pressure Test (ICP) procedure.
    2. If the engine runs rough between 3000 and 4000 RPM repeat the Air Pressure Test (ICP) procedure.
    3. If engine does not run rough between 3000 and 4000 RPM, Crank the engine and recheck the ICP graph comparison test.
  7. If the ICP PID data is not within specification, (Figure 1), proceed to the Air Pressure Test (ICP) procedure. If the ICP PID data is within specification, (Figure 1), start and drive the vehicle, monitor the engine oil temperature using IDS until the EOT reaches 195 °F (91 °C).
  8. With EOT at 195 °F (91 °C), crank the engine and recheck the ICP graph comparison test.
    1. If repairs were performed and if the ICP PID data is within specification, (Figure 1), release the vehicle to the customer.
    2. If the ICP PID data is not within specification, (Figure 1), repeat the Air Pressure Test (ICP) procedure in this article.
  9. Listen for an air leak. If a no start or hard start condition exists, an audible leak may be identified by using a stethoscope through the oil fill tube or left valve cover crankcase vent hole or by listening at the rear of the engine.
  10. If the leak is isolated to the back of the engine, go to Replace Snap To Connect (STC) procedure.
  11. If a leak is detected under a valve cover, perform the Under Valve Cover Air Leak Test procedure.
