Code Help
F150 4.9L 4WD 1992 I skinned the hot and ground wires near the fuel pump and check with volt meter with key on and got no signal to fuel pump. Fuel pump relay is good.
Did self diognostic check and got three codes: 327, EVP or DPFE circuit below min. voltage. What and Where is the EVP or DPFE located? Code 542 Fuel pump secondary circuit failure: PCM to ground. Where and how is the PCM grounded?
And, I got Code 522 but I don't know what this code is.
Please help.

EVP is also know as the EGR position sensor. It sits on top of the EGR valve.
Here is a link that may help

-- Pin 10 = A/C input
-- Pin 30 = Neutral drive
while cranking the engine or during KOEO test.
Possible causes:
A/C circuit shorted to power
Clutch engage/interlock circuits open
Neutral drive/gear switch open
Damaged processor
Starter relay disconnected during Self-Test.
