Latest info:

1) Always stalls at idle, always warm.
2) Doesn't seem to stumble, just cut off
3) Starts right up each time
4) Idles mint, accels fine (no sign of fuel starvation)
5) No electrical problems, no alarm, no accessories -all stock
5) WHEN IT STALLS, THE DASH LIGHTS DO NOT COME ON.

This morning it stalled twice within 2 minutes of each other, which could mean it is getting worse.

I am planning on changing the plugs, cleaning the throttle body, and hopefully changing an inline fuel filter (does it exist?) this weekend. Any other parts I should be looking at?

[/ QUOTE ] 1. Don't waste time or money yet,
2. Throwing parts at it...
3. You've got an electronic problem,
4. If it dies like it's been turned off.
5. Have you checked the:[*]Crankshaft Position Sensor and Harness and connector?[*]The Camshaft position sensor and connector and harness?
6. My bet's on the Crankshaft position sensor/harness/wiring/connector.

Leve,

I don't have a manual, where would I find the sensors / harnesses for the camshaft and crankshaft (front of the engine? back?) Can I remove the sensors and clean them?

1. Send me an Email to: [email protected]
2. So I have your correct Email address,
3. I'll send 2 pages out of the 2001 TJ manual,
4. That should be the same a yours,
5. And covers the CPS sensor.

LEVE,

I'm not familiar with the TJ, does it have the low oil pressure cut of switch? That sounds like a problem I've heard of with engines that are so equipped.

Don't discourage throwing parts at it, it's good for the economy. [img]images/graemlins/laugh.gif[/img]

1. Taz, as far as I know, it doesn't.
2. However, many of the newer EFI on-board computers,
3. Do have oil pressure monitoring,
4. And shut down the engine,
5. When the oil pressure's dangerously low.
6. Here's the section on the Sender from the 2001 FSM:

Leve,

email is [email protected]

Thanks.

Also, I watched the dash for the last two days (it stalled again today), both times the oil pressure was up around 40 psi at idle. Charging system at 14 volts, temp at 210, all normal.

"5) WHEN IT STALLS, THE DASH LIGHTS DO NOT COME ON."

I assume the dash lights stay off till you cycle the switch?

If so, the entire system "assumed" you turned the key off.
Check the wiring to and from the ignition switch, and the switch itself. Best way is run it and "wiggle wiggle wiggle."

And - check the position of the key itself. If the detents in the switch are worn a bit, the key - especially with a heavy keychain - can wiggle a little and actually turn the switch off. Then when you cycle the switch you're getting connection again.
Symptoms are shuts off, no dash lights, engine dies, then in a huff you hit the switch and it restarts.
Wiggle the key itself.

I had a hair-puller once like that - damn near made me bald.

Or - did you mean the headlight's dash lights are off?

I will do some wiggling, but I can't imagine it being loose or faulty wiring, at least I hope not on a 2000 vehicle.

As far as the lights, its the dash lights that don't come on when it stalls, not the headlights.
