Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hi there, TJ.
I can probably help you, but before I can even try to do so, I'd need you to answer a few questions for me:
But still no ground on the Light Blue/Orange wire from the EEC-IV computer to the FPR? Does the check engine light come on when the ignition switch is turned on?
Are you still there,TJ?
OK. Turn ignition on and check for voltage at EEC/PCM pins 1, 37 and 57. Then check for ground at pins 20, 40 and 60. What do you have?
OK. That means external power and ground circuits for the EEC/PCM are good.
Now, I asked you whether or not the check engine light would come on when the ignition switch was turned on and you replied "no check engine light"; that fact, plus no ground to the FPR from pin #22, indicate at least those two logical circuits are bad within the EEC/PCM. So, before doing anything else, I recommend replacing the EEC/PCM first, then we can take it from there if necessary.
Hi again, TJ.
Just wanted to know how you were doing with that project F150.
