I did a search through past posts, and couldn't find anything that was helpful in my case, so here goes...
I have a 96 Explorer that has had an intermittent no start for years. Lately it has been getting worse, and up till now, it always started after several attempts. Now it will not start at all.
What I have done so far: Changed the crank sensor from another running motor, no change. Swapped coil pack, still no change. Both parts removed from problem truck re-installed into donor truck and it starts.
Swapped another PCM in and no start. ( ICM is integral with this truck)
What I found: MIL turns on with key on, goes out while cranking but comes back on after a couple seconds of cranking. Disconnected the crank sensor, lite on at key on, does not go out while cranking.
I have battery voltage at the coil pack, and have 1.5 volts at both crank sensor wires. (blue and gray)
Can hear fuel pump cycle, and definate fuel smell. pulled a plug and it was wet. (not surprising with all the cranking...)
I always suspected a possible ground problem, but see nothing amiss. Although I noticed a bare wire mixed in with the crank sensor harness that goes nowhere.
Any one else go through this? Any help is appreciated!
