Yesterday I bought a 92 Z28 305 HO w/TPI. On Tuesday I heard it run. Here's the problem - I now have no spark. So far I have replaced the ECM (no self-diagnosis), distributor cap, rotor, ignition module, and coil. What else should I look for? Everything I can find is plugged in. I replaced a couple of vacuum hoses also. I tried to test the coil, but my meter has crapped out also (not been a good day). I'm going to get a noid light to check the injectors, but that shouldn't have anything to do with the spark problem, should it?

HELP!! I'm in desperate need.

Thanks for any help.

 

No the injecctors will have nothing to do with spark. You may have a bad coil or distributor

 

take the coil to autozone or someplace like that. They'll test it. If it's good my money is on the ignition module. They **** out all the time. I had a car that wasn't starting after a cam swap. Had spark and everything else. Got the no start situation fixed then I had no spark. replaced the module and it fired right up

 

The coil and module were both replaced yesterday afternoon with new parts.

I have two other f-bodies, neither with FI. Now I know why. LOL
