The Smoking Gun...

Just by pure chance I found this laying in the yard. I think it's been there since June when I changed the first module. I'm thinking this is the problem. I'm going to get a new one if I can, this one has been run over. And another module. Got a lifetime warranty...wish me luck.

Yep, that's the strap I was talking about. I guarantee that is your problem. Good luck and let us know how it goes

Thank You S10! It's not that I didn't believe you in the first place, but when someone posted they had seen setups without the strap I got a bit confused about what's going on. Somehow I inadvertently forgot to reinstall it, or it fell out without me noticing it. Maybe this thread will serve as a heads up to others when working on GM iggys.

I do have one question. I forget where I read it, but someone posted that the grease supplied with the modules is the wrong stuff, that it's dielectric grease when it should be an arctic silver- like thermal protectant instead. Any thoughts on that? I have both. Which would you use?

I would use both actually. Use the die electric grease on the connectors to avoid corrosion. Use the heat sink compound on the bottom of the module around the mounting holes before bolting it down. When you bolt it down, the heat sink compound will spread out and help to transfer heat away from the module.

I took the old module back to Advance Auto Parts where they tested it and verified it was toast. I got a new module under warranty, and a new ground strap. No questions asked, they have always treated me well. Installed the module in the distributor yesterday, dropped it in the motor this morning and it cranked right up. It's a lot easier to work on with the distributor on the bench. Verified timing with a light and also verified I have continuity from the coil to ground. On the road again!
Once again, thanks for all the replys and suggestions.

Here's what it sounds like in an old video I made not long before the car was finished, wiring was in progress at this point...
