I have an 88 fiero.. Fieroking did my harness.. I talked to him a lot about this but we still can figure out whats the problem.
The engine cranks but fuel pump wont prime or run..
The problem i have is that the ecm is not sending the signal to the relay..
What could be causing this? bad ecm or bad wiring?
wiring was done wrong 2 times but right now as far as i know the fuel pump relay is wired right and it does crank the engine when i hit the switch..
any help plz!!!!!!!!!

Is the check engine light coming on when you turn on the ignition?

What year/make/model of car did the ECM come out of? (so I can look up wiring diagrams)

Does the check engine light turn on when you turn the key on?

Are you getting constant 12v + power to ECM pin C1-20 and TCM pin 32?

Are you getting key-on 12v + power to ECM pins C1-14, C1-18, and C1-19; as well as on TCM pins 11 and 31?
