My daughters 91 firebird quits and will not restart for a while. It will
turn over but not start? I l went to pick up her car because she said it quit
on her again. We just had the ECM unit replaced, the mechanic thought that
was the problem. I went to the car and tried to start it and it would only
turn over. I winched it on to my trailer. I then went to turn off the key and
thought I would try it and it started? Anyone have any similar problems?
Thanks for your help.
It would not be VATS as that would not allow it to crank. I would
recommend checking the ignition module, fuel pump and the coil packs
(IIRC the 91 v6 had coil packs already). It sounds like either fuel
delivery or spark. You also probably should check the different
sensors. One to check would be any/all crank position sensors, since if
they fail once they get hot there would be no spark or fuel since the
computer needs those pulses to time both spark and injectors. I know
that the coil in the distributer in the v8's can go out and can show
exactly those symptoms, but I'm not sure what takes it's place in the
v6's as I don't think they have a distributer.
The fuel pump was replaced last year and has been working fine. And since it
started at a later time I would consider your crank sensor to be a good idea.
Is there a way to check the ignition module? Or is it a part you just have to
replace and hope you get the right one?
