4632R Posted October 27, 2012 Report Share Posted October 27, 2012 I have a no start issue with my 03 mach 1, there is no fuel in the rails. there is no power to the pump or the fuel pressure sensor. The fuse is good. I replaced the fuel pump driver module from another vehicle, no change. There is power in/out of driver module and inertia switch. Could it be the constant control relay module? not sure how to test it. There are no codes in pcm. thanks for feedback. Link to comment Share on other sites More sharing options...
Helix Posted October 31, 2012 Report Share Posted October 31, 2012 Hmm... Thats a toughy. Sound like either some sort of pressure leak causing the fuel not to go through the lines? I'll watch this though, I wanna know to. Best of luck. Link to comment Share on other sites More sharing options...
shel-b001 Posted October 31, 2012 Report Share Posted October 31, 2012 Not sure this would be it but check the ground to the pcm. make sure i is clean & make complete contact with the car frame. Link to comment Share on other sites More sharing options...
S8MS-01904 Posted November 1, 2012 Report Share Posted November 1, 2012 If no crank condition, check PCM. Link to comment Share on other sites More sharing options...
4632R Posted November 1, 2012 Author Report Share Posted November 1, 2012 pcm is powering up all sensors, car cranks fine, doesn't appear to be anti-theft system fault. Going to replace ccrm (body control module) and see what happens. Link to comment Share on other sites More sharing options...
S8MS-01904 Posted November 1, 2012 Report Share Posted November 1, 2012 Check fuel delivery @ fuel filter. Open fuel line @ intake and cycle pump on to verify fuel. I think it's fuel related. Link to comment Share on other sites More sharing options...
4632R Posted November 9, 2012 Author Report Share Posted November 9, 2012 I replaced the body control module and car still wouldn't run. Classic example of myself over-engineering the problem, I replaced the fuel pump regardless of not seeing power there and that was the culprit. oh well at least its fixed.

2010KonaBlueGT Posted November 10, 2012 Report Share Posted November 10, 2012 There is power in/out of driver module and inertia switch. Just for S&G's...did you try resetting the inertia switch? I can't remember, does it have 2 wires to/from it or 3? Phill Link to comment Share on other sites More sharing options...
