Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello Tim, You have a 4 pin fuel pump relay, When the pump doesn't run, (which I am assuming is at all times now?) Do you have power on the YELLOW and RED wire at the fuel pump relay with key ON? Do you have a volt meter or 12 volt test light to do some tests with? thanks.
You only have 4 wires in the harness going to the FPR. correct? that is the wiring diagram I'm looking at. did you jump the inertia switch or check power there when cranking just to see if it makes that far?
Alright, Is this the diagram you we're looking at? If you don't have duel tanks don't look at the tank selector switch, just the part that goes to the high pressure rail pump.
You we're looking at the green relay, correct? that is the Fuel pump relay, black is PCM relay.
The green relay out on the drivers fender well is the fuel pump relay, it doesn't have a YELLOW and RED wire going to it? If not, I don't believe it's factory wiring.
Look between the master cylinder and the air cleaner box, on drivers fender, should have a green colored connector there with 4 pins in it, that is the fuel pump relay. the green connector will look like this one.
Sounds good. take your time.
Alright, did you look around there, down around the fender well, they fall out of that cover sometimes.
I gotcha! That sounds good, lets try again tom. in the daylight. Let me know if you find it.
ok. sounds good.
Alright, sounds good. I will have cell only access this evening, but let me know what you find.
Tell me some good news!
Ok, was it a green connector at the relay ? Or is it still missing?
Should be right there, on the fender well, That was the factory spot.
The EEC power relay is right next to the fuel pump relay that is in a factory cover where the EEC self test connector is on the left fender well. At least that is the factory spot. Now if you say the wiring harness has been replaced. I don't think they would have moved it far, but, I can't be sure. Does the check engine light come on when you turn the key on? If so, the EEC power relay is working.
bwahaha, that is good. lemme know what you find there.
