Hey all, I have an 87 Cherokee 4 liter with a strange issue.
Three times now, the truck has flat-out died on me. The first two times were at idle at a light and in a parking lot, and the truck just shut off like I turned off the key. The third time (last night) it happened while driving around 25 through a residential area, started dying on me and I was barely able to get it off the road into a gas station.
All three times the truck refuses to restart. No fuel pump prime and the engine just spins. But if I disconnect the battery and let it sit awhile (not just a few minutes or an hour or so, has to pretty much be all night) she will fire back up.
I also seem to start experiencing loss of power in 3rd and 4th for awhile before this happens. Doesn't run rough or miss at idle, but on the highway I'll have to shift into 3rd just to keep it moving
Jumping the contacts on the fuel pump relay runs the pump fine, but I still get no start, I assume no spark but I have to check that.
I've read through a lot of posts here that mention the crank position sensor. I plan on trying to check that in the next couple days as the weather warms up. Biggest problem is that it's intermittent, and will run for days or a week or more without any issues.
Anyone have any other suggestions?
Thanks,
Jeff
