Ive been chasing a starting problem on my 93 LT1. The problem was that the car would not re start once the engine warmed up. It would start cold and run fine once started. I replaced the Opti with a new Petris unit and the problem persisted. I replaced the Ignition coil and now no start at all. It seems I'm not getting spark to the Opti.... I noticed there was no dialectric grease behind the ICM so I am guessing that it may be a faulty ICM. I'm not sure what to check or how to proceed other than trying a new ICM and hoping I can resolve. Any help greatly appreciated.

I checked the codes yesterday and in the first module (CCM) get a 41 and 54. I am not sure if this is an ECM failure or perhaps could be that the ICM is not working
