ICM keep going bad..

OK after hunting and putting out money i THINK i might have found my problem... Car has hard start no power and no start when it gets hot... changed ICM..NO START.. checked for spark. NO spark so i got new ICM still no start but some time after trying for hours it started and it would start every time on the first turn so i took it out for a ride and it was really fast.. after i parked it i tried to start it again and no start.. i took two ICM to auto zone to get tested and both are bad... Whats making ICM go bad????

Icky ICM

In many cases: the coil.

Replace the coil and ICM before firing it up.

Don’t start the engine with the new ICM with the old coil.


Happy Racing!
