Hey guys, I'm at whit's end and I need your help. I've got an 88 XJ with an auto-trans.
Last night, it began stalling out on my way home from work. I was in rush hour traffic, but I was able to start it right back up. It did this three or four times and each time it got harder to restart. I noticed the gas light came on just as it stalled or right after it stalled, but it had over half a tank of fuel. I was able to get it to run long enough for me to get to a gas station and I filled it up. After I filled it ran fine for until I was almost home and started stalling out again. I was able to make it home.
I checked the vacuum lines and visible electric connectors when I got home; I saw nothing out of place.
A little history at this point, this Cherokee has the fuel pump wired to a switch on the center consol by the previous owner. He said it would start. But not stay running. I figured it was a bad ballast resistor, but would fix it sometime down the road. To get this inspected this past summer, I had to replace the exhaust from the cat back. I had to replace the O2 sensor and gave it a tune up. Any way I checked all of this wiring for the fuel pump and it all looked OK. So I got in it and it started right up. I drove it around the block and it ran fine.
So this morning I get in to drive it to work. It starts right up and I’m on my way. I again figure I will check things out this weekend and a way I go. I get 20 to 25 minutes into my commute and it stalls. I was able to get it to the side of the road and it starts right up. I let the engine run a few minutes in park and it seems fine, so I get back under way. I few blocks down the road it stalls and then this time I'd have a horrible time getting it started again. It is strange in that when I crank it, it starts up, revs to about 2500 rpm and then dies, without me touching the gas pedal. I try to pump it and as it dies it sounds like a motor that has the choke closed. I just had it towed home and asked my wife to start it up (I’m working ). She said it started right up and she drove it into the garage. Any ideas where to start?
