So with my car running rough having starting iasues and being rich I took a guess on the ignition module picked one up put it in started ran till parked then had issues starting wouldn't run more than 10 seconds without dieing. Got a replacment figureing a bad one. Put new one in wouldn't even kick over. Put old in and fired up? Any guesses?
There are a lot of bad ignition modules right out of the box. I recommend Delco
A bad coil can ruin an ignition module. Bad spark plug wires can ruin an ignition module
All the above from experience...except Delco. I had more Delco failures than Autozone ones. I bought a whole brand new distributor from Chevy for one of my Corvettes. The module was bad out of the box and they wouldnt replace it. I put an Autozone one in it and no more trouble.
Your’s could be a common problem and don’t cost anything to check. Try this: Watch the tach when cranking if it don’t move you're not getting pulses from the distributor. If so, it could be a faulty module in it or more likely simply corroded connectors at the base of the distributor. Reseating those connectors a few times could clean the pins some and also do the same to the connectors on the coil etc. These cars are old, and old connectors corrode. Such can also manifest itself as intermittent misfires, and engine cutouts.
BTW: lots of folks keep replacing modules and coils thinking they are bad because the new ones FIX the problem, when in actuality the fact that they simply unpluged the connectors and repluged them into the new unit cleaned the contacts enough to make it work again, at least for a while. It's smart, to replace those old connectors with new ones. BTW: Cliphouse has those connectors
