Whats the chances of that???i checked all plug gaps and all wires have fire.....so im hoping the icm failure is pure coincedence. i checked the old icm connections for corrosion there is none......thanks.
you swapped the the coilpacks and the truck ran the same and then same wires had no sprak?
you could go to a junkyard. I know that the 91-97 4 bangers are all the same module......maybe even earlier...............it sounds strange that you did the work and at the same time blew out the ICM....however, they are a common failure and the #2 and#3 are a pair
