Be real interesting to see if the injectors are getting voltage on cranking.

We have a nice strong flash from the noid while cranking. No spark from the coil wire grounded in the compressor like in dons vid. So we have a good crank sensor a good sensor ground ecu is telling the injectors to fire and no spark. I have good voltages and grounds up to icu and the contacts are cleaned tensioned and dielectriced. I'm about ready to go grab a icu from the scrap yard.

So the front yellow is getting about 12, the rear yellow is getting about 5, and the ground is grounding. (second one, black). I guess, I don't have a better idea. I've never separated my coil and ICM. If I had I'd be able to provide my coil resistance numbers. I put what I could find in post #61.

Yes that is right don. I went and found 1 renix with icu still it had a coolant bottle blow on it everything covered I rusty water. Hope it works. On the other hand I found a waggy with perfect steering wheel in the same color as mine was so I got that and a waggy grille I should have snagged the header panel too. It was all there just one broken bezel but another 2 door waggy next to it with the correct bezel.

I'm working out a way to do it with just stuff from the Dollar store. I'm thinking it should work to test a a 91 to 99 CPS/puter', and their wires as well. Rock's for Renix! Moving forward!.
