I need to diagnose a problem on my Firebird. I'm trying an F-body forum but the responses so far recommend that I just replace parts. Typical GM eh. I'm going to try to avoid doing that. I have a Haynes manual but it's junk for trouble shooting. I would like to determine with reasonable certainty that it is good or bad.

It's an '88, computer controlled ignition. The distributor simply tells the computer where the crank and cam and so on is. No advance mechanisms. It's an external coil setup.



Yep. As soon as I fix one problem, another comes up. To be fair, though, I haven't had to do much to it in 42000 miles. And at 132000, a module going out will be nothing to complain about.
