Give me a dope slap, too.

I think that on the connector to the ignition module, pin A (yellow wire) should be +12 volts from ignition switch, pin B (also yellow) should be the trigger signal from the ECU, and pin C (green) the tach signal. Diagrams I have for this are a bit fuzzy and I've been out of the Renix loop for years, but one of those should get you 12 volts +. I don't find any procedure that tells what, if any, measurable signal you should be looking for in terms of ECU input to the coil. Of course the number one suspect for no spark is still usually the crank position sensor, but a bad one doesn't usually give you an ohmmeter reading.Ok, it wasn't the CPS LOL. No spark. Jumped the fuel pump and it shoots out of the fuel rail like crazy so the pump is good. Time to check the power in and out of the coil I guess. Have to look that up. If you have a link to that or advice speake up please. Thanks again guys.
Well, I was out testing all the wiring and such and everything was checking out fine. I saw some where on to check the grounds at the dipstick so I was moving the wiring around and didn't see anything necessarily alarming there. I plugged everything back in that i had unplugged and turned the key and it fired right up. Guess its time to sell this one!
Not really, just run through things again, this time cleaning all making sure they are stripped to bare metal and treating them with anti-corrosion and making them tight as possible. Those dipstick grounds are for the ECU, the ICM, the o2 sensor and more--CRITICAL.
Also, the Renix coil clips to the ICM, make sure the clips are clean and treated with dielectric grease too.
Yeah, I don't have that silly firewall connector. I had an '88 parts jeep that did and I could see that thing being a problem. I am going to degrease the wiring over by the dipstick and get it lubed up and I was thinking about making a new ground strap for the back using some 8 gauge subwoofer type wire - or if I can find that cable new. Mine looks good but it may not be.
Ok, I actually have a couple brand new battery cables I am going to make up a nice ground wire to go from the inner fender to the dipstick tube bolt or something in that order. Thanks again guys.Pick up a 4 or 2 ga cable at any parts store if you are talking about the head to firewall ground. Braided cable straps are self-destructing crap, IMHO.
