i replaced my opti and my radiator lasrnight it started fine i drove for a while turned it off and cranked it about 12 times then came back out it won't start now i have a msd box and a 3 month old msd ignition coil and i realized that it started with the ground wire unhooked from my icm i did a spark check im getting fire off the opti but not off my coil could i have short out the icm or what they cant test it at out autopart store here so i would like to know what you guys think before i go buy a new one.......does anyone have a wire diagram for a icm without the msd box and is the icm what fires the coil
