'92 F-150, 5.0, E4OD - My truck died on me a couple of times when I was on my way home the other day, and it was only when I was coming to a stop, but it started back up again. Then when I went to park it it died again and wouldn't restart. So I started looking around and saw that a couple of plug wires were burned through a little so I replaced those and the plugs figuring that it would fire right up...nothing. I haven't got around to making sure that there is actually juice getting to plugs yet, I going to go check that in a minute, but I know its getting fuel. The distributor cap didn't have any apparent damage, the coil is only about 6 months old and I have a MSD ignition that is about the same. Anyone have any ideas?

 

Doesn't seem to be any spark coming out of the coil, checking all the connections next.

 

I also pulled the codes, nothing but a couple of O2 codes saying it was running rich and a couple of EGR codes.

 

Starting to feel like I'm talking to myself, anyways, its not the ICM and I don't think its the coil (I put on a used coil that I think works, going to look into that more tomarrow). So to recap: turns over, won't start, no spark at coil, plugs, wires, and ICM have been replaced, and connections look like they are all good. Anything I'm missing other than the distributor?

 

By ICM do you mean the TFI Module?

 

Ignition Control Module, and I don't know if I mentioned, but it is getting fuel.

 

I think we're talking about the same part...
Check the wiring and voltage to the coil.
The primary side should have 12v constantly and the secondary should pulsate as the dizzy spins. If you ohm the primary/secondary neither should read open.

 

PROBLEM SOLVED : it looks like when my plug wires shorted out, they must have shorted out my MSD also. After switching everything back over to stock, it fired right up. Of course that was after an hour of testing because I didn't bother to try and start it after I switch everything back over. I'll blame that on the heat, 95 degrees with the sun on my back and no breeze.
