About to tear my hair out with this car.

Car died last fall while ideling triggering a fresh rebuild, new gm optispark, etc.

Coil had no spark.

Icm works, tested on dads suburban that uses same icm.
Wiring to icm is correct via shbox site.

Opti harness is correct via shbox site

Opti pigtail ( ord coming out of opti) passes signal through


Ran for a min this morning and tried to fire last night.


Ideas?

Don Anesi

Thanks Don, very helpful.

It was the plug for the ICM. When twisted up to test it was fine, when plugged in it was bad.
