Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.
Tony is not on at the moment , is there something I can help you with?
So your saying you have power on the red battery wire at the starter but none at the yellow/blue start wire at the starter?
Okay start first with making sure the F1-12 fuse located in the under hood panel is in place and not blow and if it checks okay check and see if you have power at the starter relay on pins 30 and 85 with the key in the crank position. See the start circuit wiring in the link below for testing reference. Check this and let me know.https://dl.dropboxusercontent.com/u/104923897/Starter%20Nov%2015.pdf
Okay dose the engine crank over if you supply the relay with a ground at pin 86 with the key in the crank position?
Yes , the Relay gets its ground from the PCM (computer) one the PCM has read the key and if the PCM is reading the key and you have power on both the power pins and a good ground at the relay and it will still not crank then that would point to a bad relay. Try swapping it with a know good relay.
Are you feeling it click when you go to the crank position?
Okay Then that means that either the theft system is not reading the key so the PCM can ground the relay or the PCM has failed . I would suspect you have a problem with the key. Have you by chance tried the spare key ? If not then do so. I would also scan the system and see if there are any theft codes setting.
If the PCM can not read the key it will not crank and or start as it kills injector pulse as well.
The only way to do that is with a dealer scan tool or in some cases a lock smith can come out and do it as well.
Unfortunately yes, the common cause is in most cases a problem with the key but it can also be a failing PCM. Scanning the system would be the next step to determine the cause.
Yes the post stays open even after you rate my service for as long as need be. All you need to do is post back and we can work from there. Please take a moment to rate my service so I can get credit for my time, the question remains open for follow up even after doing so, all you need to do is return to this question if need be.Thank you again.
The code B1352 indicates a Ignition Key-In Circuit Failure.The code B1318 is a charging system code indicating low voltage.The Code B1369 indicates Ignition RUN/ACC Circuit OpenCode U1950 from the Drivers Seat Module (DSM) suggests that it is detecting communication issues with at least one other member of the Uart Based Protocol (UBP) network circuit which includes the HEC.
You likely have a problem with the key as well as the cluster and the PCM . Unfortunately this is going to require some hands on testing. What codes return if you clear all of them?
This code indacates a Ignition Key-In Circuit Failure. Dose the instrument cluster seem to be working with the key on?
Okay then I would suspect you have either a bad Key and or the PCM has failed but this is going to need some hands on testing.
With all of these code This is not something I can fix from here. If you would like I can open the post back up for you and perhaps someone else may have something different to add.
Doing so now.
Hello, This is Tony. My good friend Ron was working with you and OPT OUT to open your question to me. I read over your comments back and for with Ron and he did cover all the important items.
I just want to check one thing.
Does the yellow check engine light come on when the key is turned on?
Thank you. And you have no actual trouble codes from the PCM (Engine Computer)?
Ok, there is a RED theft light on the dash that flashes every 3 to 5 seconds when the key is turned off and the doors are closed. See if this light flashes rapidly when you turn the key to on.
