No spark at all.
In all honestly I don't know, I think the ICM sends signal to the ECU(PCM) which sends it to the coil and the tach? I don't know this is way over my head. Which sensors messing up would cause no spark I also don't know, there's only 2 sensors below the head gasket, oil pressure and oil level I would think it would spark if either of those was bad, the rest are on the head, intake and exhaust,
There's 12.3-12.4v on the coil wire to the dizzy when the switch is in the run position, 10.something when cranking. with the old coil it was 11.7-12.1 in run. I thought it was supposed to be a lot higher voltage going across the coil wire
I think this might be one of the set-ups where even a bad alternator will cause no spark.
Next step is to pull any codes, something I should have done long ago. I know it's time to admit I'm in over my head but hopefully that computer will tell me enough to know what's wrong without having some stranger snooping around in my engine bay or having me probe holes in a bunch of wires.
