My car died on me today and had to have it toed. Its a 72 Nova with a 94 LT1. Everything has ben changed before it was installed in car. I replaced Opti, plugs, wires, coil but I didnt change the ICM before install. I have 50PSI fuel pressure. I dont have any spark at the coil or plugs. Car does crank. I let the car cool off and tried to restart but nothing. Anybody have any ideas? Thanks for your imput.
