Readenour

i was driving down the road and my car died, tried to start it again but nothing. so i had it towed home. so first i thought it was the coil, nothing, next i tried the icm, same thing, finally i decided the optispark was the problem since the other two common lt1 problems didnt work, and still nothing. im stuck and i have no other ideas. im getting fuel and all fuses have checked out good. please help btw i have a 1994 z28 and its not the security system

Describe exactly what happens when you turn the key to "start".

Have you scanned it for codes? Have you checked the fuel pressure? Have you checked for spark?

Not sure why you deleted the thread on "LT1 Based Engine Tech" and reposted it here. This is an appropriate topic and there's more traffic on the LT1 forum.

You'll get better results if you keep it all in one thread, so everyone can see what others have suggested, and hat you have tried.
