I have a 92 camaro RS 305 TBI and the car was running fine until the other day when it randomly would not start. The engine is cranking, but will not fire. I took the ICM to autozone to test and they said that it was good, so then I grabbed a spare ignition coil that I had and plugged it in and the car fired up no problem. I then went to autozone and bought a new one, I put it in the car and the car ran fine. I took the car for a short drive around the neighborhood and then parked it.
I went out this morning on my way to work and the car would not fire again. I switched batteries with my other camaro to see if my battery was bad and the car still would not start. I switched the ignition coil again and still nothing.
I am not sure where to go from here.

The first time the car would not fire I noticed that there was no spark and I did not see fuel coming out of the 2 injectors while trying to start. I am waiting for another person to come over so they can crank the car while I check for spark and fuel. I will post what I come up with.

Any help would be much appreciated.

 

Until you identify which it is, a bit hard to talk your through the diagnostics

While you are waiting , you might read this on how to identify a no spark problem . 6 Pages
