(88 XJ-ltd, 4.0, auto) Ok so i have been having this problem since i got my cherokee. I should note that this only happens during or after it rains or is moist out. What happens is my XJ stalls instantly , no sputtering, and the fuel gauge jumps to full which it rarely actually is. Now I think i know what the problem is but my attempts to remedy it have failed thus far. underneath the vehicle near the tank the previous owners in all their wisdom stripped the coating off of all three wires that go to the sending unit. Probably some attempt to verify the pump worked.
Would wet conditions cause voltage to bounce between these and short out the pump? Thats the only thing that makes sense to me really. I have used a cruddy old can of liquid electrical tape and then wrapped the wires up with black tape but it still seems to do it after driving in wet conditions.Just wanted to confirm i am on the right path before i redo everything. Another possibility is a short after the wires enter the unibody through the rubber grommet...do the continue there till the engine bay or do they come up through the floor into the cab?
