yj stalling issues....still

alright well I just spent $600 getting my jeep running after shutting down on the highway. I hate to say it but I payed someone to do it because of school and work. long story short...

jeep stalls on me once and a while, but tonight was bad. stalling every couple seconds/minutes. very frustrating after spending so much money.

new starter
new battery
new icm

running weber carb, not nuttered.

the stalling is like someone turning off the ignition.

could a bad ecm or ignition switch be my problem?

Why have you not nuttered if your running an aftermarket carb?

When it turns off, do all the lights, radio etc go off too, like there is no power at all, or does the engine just cut out?

I have not nuttered yet due to having issues passing emmissions. the stock emmissions stuff was just enough to get me to pass.

all lights and accessorys stay on. just engine cut

ICM, coil, distributor, or bad ground for ICM/Distributor. ICM should still be under warranty?

If it was a bad main ground, everything would go off. If it was the ignition switch, at least the radio would go off.

I hope you didn't pay $600 for just those 3 things.

How long have you been running the weber with out problems?
If you havent nuttered it the computer is still trying to control timing among other things. A far as emissions, IIRC, many of the vac switches are relying on input from the computer which again is wanting to talk to the carter carb that is no longer there. The pulse air system still operates after the nutter and can still be used if you've modified the oem air cleaner to fit the weber or an after market air cleaner to fit the pulse air tubes.

When you say it stalls every couple of seconds that sounds more like cutting out or a miss which definitely be a timing issue, or do you mean stall as in you have to restart the jeep every time?

I've had this problem since I bought the jeep. its more of an electrical shutoff rather than a fuel delivery problem. timing is dead and even got a brand new timing set. could my ignition switch just be old and worn out? it doesn't seem to like water/humidity

If you are running a different carb the ECM isn't doing what is was designed to anymore and neither is the stock emissions stuff.

It's possible the ignition switch could be bad, not the key switch but the actual ignition switch behind the dash on top of the column.

How are your battery cables? Those are known to go bad with corrosion and breaks inside the insulation.

He said his accessories didn't go off. If it was the ignition switch, the things that don't run with the ignition switch off (radio, lighter, windshield wipers) would go off when it died. If it was the battery cables, everything would go off or at least flicker.

It could be any one of over a hundred things, and possibly a combination of more than one fault.

You will likely go broke before finding the problem by paying someone to throw new parts at the problem.

You can fix it if you do a systematic diagnosis of the problem. The factory service manuals have encouraged this approach since the 70s with their flow chart diagnosis chapters.

Every part on the jeep can be inspected and checked for proper function. It takes time, but you know it will be fixed when done this way.

The weber adds another layer of confusion. It may have been installed to try to fix an unrelated problem.

Re your timing chain: How many degrees of slack did the old one have when replaced?

Did you just get it back from the repair shop? I would take it back and let them do what you paid them to do. thats a lot of money. Are you still having the issue?
