Engine shutoff

Steigs · Aug 29, 2004

So I'm driving to work the other day and I'm about 3/4 of the way there, when I stop at a light and the engine just shuts off. No warning, no sputtering, gauges are all in normal range. It took a bit of cranking and a couple WOT's to get it to start again. I wasn't overly concerned about it at the time, figuring it was just some random thing. Driving in today, the same thing happened at about the same spot. Now I'm wondering w.t.f. is going on? Like to nip this one early before it ends up stranding me somewhere, or stalling me in the middle of an intersection. It's only been these two times so far, but I think that's about 1 more time than I'd like...

Any thoughts?

blocked cat? loose eletrical connection? bad sensor... could be a million things

Yeah, I know... I guess I was just hoping it might be one of those "part x has a habit of..." type of things. Cat is new, don't think it's electrical as there was no jarring or anything to knock a connection loose. Probably a sensor, though which one would shut the engine off? I'll try and pull some codes today and see where it gets me.

yeah talk about weird. it reminds me of when i had a camaro. every time i parked it in the grocery store and certain other places, the key wouldn't be recognized. if i pushed it away from the lamp post, it would start, pull it back, it would die. finally a mechanic said it was due to electrical interference. sometimes i'd even drive under certain street lamps in my neighborhood and the lamp would go out. i loved that thing but it was cursed with ghosts or some $hit and had to get rid of it.

I feel ya buddy!! Im having the exact same problem right now!!! It didnt happen until I replaced the converter, then the o2 sensor showed its ugly face with the sewer smell, then the coil went out. Replaced the coil and o2 sensor, wow, it ran great and idled GREAT. But every once in a while it just shuts off. I dunno. Ive been told that the crank sensor or ASD relay can cause that very problem. So Ill keep ya up to date.

Solved.

Pretty stupid, actually...

There was a pinhole in the heater hose that was causing coolant to leak onto the coil and short off the ignition. I've had the problem before of having to wipe off condensation on a damp day to get the Jeep to start, but this was the first time it caused it to stall.

Anyhow, new hose solved the problem (duh). Figured I'd update this in case it might help anyone else.

YMMV
