I picked up a non running 86 GT w/ auto today. I just can't get it to run. The car turns over almost runs and then goes back to just cranking Here's what I've done new fuel pump and strainer new fuel filter tested coil- good cap rotor wires & plugs are good I have the correct fuel pressure adjusted timing relays are good - i pulled them out of a running fiero changed out the ecm from a running car The relay pulls in, but the pump does not run when the ignition is first turned on. When I try to start the car the fuel pressure drops and the pump comes on and I get 40 lbs of pressures. I did a compression test -good I just don't know where to go from here.
Originally posted by 1MohrFiero: How was the coil tested? The primary (only) can fire and give you a spark but it is too weak to run the car. It will appear more yellow the blue. Second guess, is the distributor indexed properly? Could it be a couple of teeth off? Third guess, it is possible to get a bad module out of the box.
Okay, that would have been my fourth guess! Just kidding, that would have been a tough one to find. Good work.
