Pm me if you want ill swing by and help you with it. There’s an auto shut down relay that gives power to the injectors and coil. They share the same power source. I’d be willing to bet that’s the issue.

I was wondering about that. My 94 had the same thing. However I would think if that was it, I wouldn’t think it would get power to the ICM. The same goes for the crank sensors, cam sensors, etc.
