I have a 1990 Celica with a 4AGE ST swapped into it. The igniter and coil are on a bracket together and bolted to the body. I was replacing coolant temp sensors today and unbolted it from the body and set it aside. Once the sensors were replaced I started the car and everything was fine.
I realized I didn't bolt the igniter back to the body so, with the car running, I picked it up and immediately the car shut off. And when I say shut off I mean no power at all, not even accessories. I unplugged it all, including the battery, to reset the ECU. Turn the car on, it has power. Try to start it, completely shuts off again. I unplug and reset everything again and now I notice that the bracket is, like, arcing on the body of the car. When the bracket would touch the body I could see and hear little sparks. I've never seen that before.
Since the car kept losing power and shutting off I jumped it to my other car and tried to start it. When it was jumped to the other car it would stay on and crank over, but it would not start. Once I disconnected it from my other car it would lose all power again once I tried to start it.
My thought is the igniter is bad, obviously, but with it arcing on the car it has me concerned there is another issue. Any advice? Is something like that typical if the igniter is bad?
