I will try to keep this as short as possible.
I drove my tiva (92 L bone stock, 5spd) about 90 miles to watch drag races, when I tried to start it to leave it would only crank, checked and found no spark.....sigh
Biglay5150 came to the rescue and towed it to my shop, Thanks a bunch!!
Checked all the basics, main fuses good, timing belt ok and in time, cam turning, rotor good, cap good.
I found the main battery ground cable and the smaller ground with it just hanging, the bolt had backed out at some point. cool, install new bolt....still nothing.
Test the distributor, it fails. cool, order one in and just because I test it and its perfect, install it and still nothing.
Test the coil, it checks out perfect.
Test the ignition module (ignitor) it fails as well, order a new one, still nothing.
We hook our Genisys up and look for any codes, nothing shows.
I was setting in the car tracing wires to test and my buddy was looking under the hood, I out of the blue see the check engine light pop on (key was on) I asked what he did. The cel had never worked even when you turn the key to the on position, I had replaced the bulb, didn't think anything of it, the car ran great and I had put about 1k miles on it.
He had unplugged the VAF, plugged it in and the light went out, hmmmmm...... we unplugged it and checked for spark, it was great.
The VAF was killing the cel circuit and the ignition circuit.
Biglay5150 came to the rescue again with a VAF unit, I made sure to have a 6 pack on hand when he showed.
We put it in and the car was finally fixed.
Best we figure is that some how with no ground it took out the dist, module and vaf.
I got this car and never had a chance to go over it before I had to put it into commuter service. Lesson learned.....always check em out good.
Lots of little boring stuff left out but I hope this will help someone in the future.
