Hey I have a 1996 chevy caprice with the LT1 in it....parked it last night and it was fine and then it would not start today...nothing changed. So did some tests and we have plenty of fuel getting to the engine, and we replaced the icm, but now we still don't seem to have any power in or out of the coil. It just keeps cranking and will not start. Does anybody have any ideas?? It also has had an aftermarket tach for a while that someone said could possibly be causing a problem if a wire rubbed through??
