I havn't posted on this but I thought I would share reasons why my 1996 Z28 would not start. First, I felt a miss on the way back from the store. Then, after getting home, the car would not start. My coil wire and MSD coil connector were corroded, so I changed them. Still wouldn't start. I did all the tests suggested on this site and couldn't come up with the problem. I changed the ICM and still nothing. Finally, I changed the opti (4 hours of work) and would NOT start. Frustrated! Did some more searching on this site and found on the advanced tech to try the connectors to the ICM and others. Well, guess what? I bent the connectors on the ICM when testing all those times in between changing the opti and other parts. So, in conclusion, I think it was the opti originally and then after the opti change I ended up bending the prongs on the connector for the ICM back in place. Those were the problems. Sorry so long. Thanks to this site, saved again.

 

Nice to see a FIXED thread. Someone down the road may benefit.
