not getting power to cylinder 7. After trial I only have two options left, bad wiring or bad ecm. Im inexperienced to ECMS. What is the pinout for this ECM and how do I test it? On another side note, how much voltage should be coming out of the connector for the ignitor coil?

 

If I remember correctly one pin is battery voltage, one pin is approx 5 bolts but fluctuates based on the firing signal, the other is ground.

If you can back probe a functional cylinder to get values for reference that’s best.

I’ll get eyes on a connector today and see if I can’t tell you wire colors.
