No spark after ingition module replacement

OP the other route you might consider is to replace the Mopar module with a 4 pin GM HEI module. The problem with Mopar modules is that they are basically obsolete, so most current replacements are cheap junk Chinese imports.

The GM module basicailly wires up the same as a Mopar without a ballast. You can use a better coil but you don't need to. You do need to mount it flat on a heat sink, and there is a locator "tit" on the heat sink side which must be removed. Many of us run these. I even made an "emergency" version, which I've also used to test fire used engines

I believe TrailBeast came up with this fancy diagram

My redneck "emergency roadside HEI"

You connect to the dist, ground, and battery and off you go
