I have posted on this before with no avail. If anyone will help i would appreciate it, i have a 94 ranger 2.3 with the dual coil packs, i bought it with the second coil pack not firing( since it is designed to start on one pack and then the other kicks in, this never happened) i replaced the EDIS/ICM and it would not start at all, put the old back in and would not start, have replaced a few wires on the connectors for the edis because of corrosion and check relays and fuses, still nothing. it cranks and cranks just no fire, it has no spark.

any help would be awesome

 

I had the same issue with a 92 2.3. The replacement ICM from FLAPS turned out to be sporatic. Put the orginal back on a no dice. It was the 2nd new ICM that did the trick (that and shaking the wiring harness looking for a short). The store swapped out the ICM under warentey.

Another option is that with the old wiring having been twisted/moved, maybe a wire broke in the harness. So grab the harness and give it a few shakes and jostles then retry to start it.

And don't forget the heat conductor paste between the ICM and manifold. Good luck

 

Thank you. I have tried wiggling every wire I can get my hands on lol.

and as far as the ICM I haven't bought new because of the price, I have switched it out with 2 from the bone yard, the one that is in it now had virtually no corrosion on it and look somewhat new. I do have the special silicone between it and the manifold. And all 3 bolts tightly down.


Until something pops out I'm just going to keep switching out the wire ends that look corroded.
