Hey I have a 1995 Corvette that cranks but won't start. First we found the battery terminal was loose. We fixed that and it ran good for 2 days then wouldn't start back up on the next day. We have changed out the spark plugs, wires, coil pack, optispark, and checked fuses. We are also not getting a spark when trying to start it up. Please help!!!!

I would take the coil and icm and have them tested most parts stores can do this. But many do not know how even though they think they do so take the icm to many places if it test good.

Just had them checked and both good any another ideas?

How many places checked the ICM? When was the opti put in and what kind?

you change all of the ignition components at once? if the ICM, Coil, and related fuses. Passed. this narrows you down to the replacement. opti.

I would start diagnosis over do not assume you have good parts...maybe you got a "dud". Hopefully you have FSM or access to quality service information, and have not guessing with parts.

Thanks for all the help guys just got it running tonight it was the pigtail wire running to the coil pack. It was burnt up causing the electric circulation from going around.
