I took off the ignition module off my 91 camaro how do i check if it's Good? the reason i took it off is because my camaro won't start and i got a new ignition coil and still no new results but i researched it on the forums and stuff and people with my kinda problem got a new ignition module and it fixed it. But i dont want to drop 40 bucks on a new one (high schooler going paycheck to paycheck) and wanted to know if there is any test to see if it's good or not?

 

There are many modules in your module (ie, it does several things!).

You can't just meter it or something if that's what you're asking.

Most places like NAPA have module testers (well, so do I, but...) and will check stuff out for you. One thing to remember though, is that they'll be testing it at room temperature, and not under load. It's still possible for it to check out OK, but to fail in a real world situation.

Shall we assume you checked for spark during cranking, got none, and that's why you targeted your module for your no-start?

 

yes you shall assume that and be correct. so like autozone would have something to test it but it won't test it under load? which means....

 

They'll test it, but as I said... it's on a bench.

It's different when it's heat soaked from the engine, and it's actually switching the coil (the worst part of it's life).

It'll give you a start though. It might just show up as bad! It IS a high failure rate part. You could also just get a junkyard one and try it.

Make sure you use a THIN layer of heat sink compound on it (just like a CPU) after cleaning the two mating surfaces.

 

Whenever I get in one of those, I always change the module and the pickup coil. They should both be <$20 each. Clean the shaft while you have it apart and make sure there is no wobble in it. Don't forget the heatsink compound under the module.

 

ok how do i change the pickup coil?
and the heat sink compound?
suck it stinks being a newb lol

 

Take the dist out. Drive the rollpin out of the gear and remove it. Pull the shaft out of the dist. The rest is obvious. The new module should some with compound to put under it.

 

Posing to do the same thing shortly, let us know how it went and if it fixed it......

ok i got the dist sitting right next to me but im totally stumped on how to switch it i do not understand your directions jv9999 please break it down more plox

 

Here is a great write-up with pics that helped me out in a similar situation.
