Ford Repair Questions? Ask a Mechanic for Answers ASAP
First of all, is this a gas engine?
Second, can you hear the fuel pump run when you first turn the key to run?
Ok, that is close to what I asked, but I asked if you can hear the fuel pump run?
Ok, I want to look at the wiring diagram but I need to know what engine came in this?
Also, have you checked the fuel pump fuse and relay and inertia switch if it has one?
Ok, exactly what were the results of these tests?
In the power distribution box, these fuses should be checked, fuse #24, fuse #19. In the junction box fuse/relay panel, the fuse #30. No, the pump would shut off after 2 seconds.
Here are the wiring diagrams,
If the fuse pump relay has no power with the key on run, check that pcm power relay. But first check the fuses.
Did you test both sides of each fuse with a voltmeter or 12 volt test light? If not, do that. Then remove the fuel pump relay and test the prongs in the socket for voltage with the key on run. You will have to have someone else turn the key to run cause you will only have 2 seconds to test one of those terminals.
One terminal in the socket should be hot with the key off, that comes from that fuse #19 in the pdc, the second should be hot with the key on run for the first 2 seconds, that comes from that pcm power relay.
Actually it may stay hot, I think it's the ground circuit and the ecm that stays on for those 2 seconds. Either way, there should be 2 spots in that fuel pump relay socket hot with the key on run. either all the time or for only 2 seconds. So let me know.
So, if only one spot in the fuel pump relay socket is hot with the key on run, check that pcm power relay in the same manner. Remove the pcm power relay and test the socket for power. One spot should be hot all the time, that comes from that fuse #24 and an additional hot when the key is turned to run, that comes from that fuse #30.
Any news yet? I am going out soon to work on my own car, so if you reply, I'll respond when I check back in.
