On my 93 lumina 3.1 it will try to start and sometimes start for around 15 seconds then die or if you give it gas imediatley dies. This sounds like a fuel system problem to me but also, if you jump from the a to the b terminal on the diagnostic connector then turn the ignition on, the service engine light should blink once pause then blink twice. Mine does nothing. Does this mean the ECM is bad? Is there a way to test them?

Thanks, Kyle

1st check the ECM fuse before replacing high $$$$ parts.

I did, it is good.

Check the fuel pressure for starters.

i have the same issue with the car, it reads spark control module failure, does anyone know where on the car that is located?

There are at least 2 if not 3 ECM fuses on that car. One in glove compartment panel, one by fuel pump relay, & some have a 3rd in right hand elect. panel under hood.
