As far as I can see the Ignition Coil and the PCM Computer are the only two items that could heat up the ICM. Only other factor would be low voltage on the wire from the Ignition Switch.

So I made a small mistake because I couldn't see the plug wires at all running to the plugs on the passenger side. I had two wires on the wrong posts of the dis. cap. Remedied that and the truck was running great. Put the new distributor in again and it was running even better. So far no problems or hiccups. We'll see if that helps us out. We'll also keep an eye out for a Ford dealer to get a new coil at. Thanks subford for your help. It's much appreciated. Will post again if I can get a coil and update on progress.

1996 5.8L won't fire

I am having a similar problem with my 96 5.8L, sometimes it starts on a couple of cranks, sometimes not at all. I had it running on day and it just stopped and would not start again for a week and I tried every day, when it did start it fired right up after a couple cranks. I am not driving it very much as it is not very reliable and want to sell it, but I want it to run proper for a better sell. I replaced the rotor and cap, ignition switch, and still no luck, help is needed.

Hey Guys,

So it was the pip sensor in the distributor... Or at least something in the distributor. After were replaced the distributor with a new one and got the spark plug wires where they are supposed to go, we had zero running problems. No over heating ignition control modules, plenty of power and better economy. About 2.5 mpg better. Got over 17 mpg on the highway. We made it home fine. About 2000 miles of continuous driving. Was a wonderful feeling! Thanks for all the help everyone! It was much appreciated!
