Jeep Wrangler Problem
Today | Me

Posted on 10/16/2013 9:22:15 PM PDT by Anti-Christ is Hillary

Ok I know we don't have a lot of car questions here but my husband can't figure it out and there is not a lot that he can't figure out. I have a 2000 Jeep Wrangler Sport. For the last few weeks it has been dieing its like it just turns off. I'll be traveling down the street or on the freeway and everything is fine and all of the sudden it just dies. He thought that it was the fuel pump and changed that and now he is thinking that it is something in the electrical system. Does anyone have any ideas? He put a code reader on it and got no codes back.

Thanks for any help.

Nikki

Change the fuel filter

Is there a fuel filter? Either inline within the hose or screwed into the carb body. Today’s fuel isn’t always so clean.

Quite possibly a fuel filter. If at any time someone inadvertently used a poor grade of fuel (dirty or containing water) it may have partially plugged up the fuel filter.

I had a similar problem with an older vehicle that I had bought as a converted camper. There was some rust in the tank and fuel line which would allow the engine to run for awhile and then completely die until the rust fell away from the filter element.

Replacing the fuel filter complete fixed the problem and I was able to drive that vehicle from Chicago to northern Minnesota where I spent the summer as a horsemanship instructor at a summer camp.

If the problem is the fuel filter and there is dirt, rust or some other sediment in the tank, It may be necessary to replace the fuel filter a second time after some more debris moves from the fuel tank and/or fuel line into the new filter.

My converted camper was a former school bus on an International Metro body which had over 300,000 miles on it which I bough very cheaply after it had an engine valve job.

After it stalled and I removed the fuel filter I was able to see the filter almost completely filler with a rust like sediment which occurred because the truck had been sitting unused for a long time.

The rust was caused by water in the gas separating from the gas and sitting in the bottom of the fuel tank. Running the engine caused the rust to be sucked up into the filter while not running the engine allowed the rust to fall away from blocking the filter.

On further thought, I also had a much newer Ford Crown Vic which also exhibited the same problem in which it suddenly died while I was driving on I4 in Florida.

Again it was the fuel filter but this time I had to have the car towed to a local shop and spend a lot of time waiting for someone to get a new fuel pump and replace it.

The Ford did have fuel injection while the much older converted Metro did not. In both cases it was the fuel filter which was at fault.

It was the “TPS” (throttle position sensor) on my 1998 4.0 liter straight six Cherokee. Fairly cheap and easy to access on top near throttle body. It is a “potentiometer” and after 100K miles or so gets worn spots on it that throw “static” to the engine/injector computer causing rough/jerky/stalling. Like a dirty volume knob on an old AM radio. Good luck!

One very remote possibility is the switch which cuts off the electric fuel pump in the event of an accident. That is not likely your problem but is not impossible.

Is there still power to the console/dash when the engine loses power?

Is there auxiliary power?

Can you start the engine immediately after it loses power?

Does it run rough prior to stalling?

Does it stall at low speeds?

Does it stall cold or only after the engine warms up?

I had this problem with my 1970 Dodge. I asked at the local parts house what it might be and they said, “check for a burned spot in the wiring harness at the base of the steering column.” BINGO! I insulated that and it worked until I got rid of the car. So, look for an intermittent in a cable someplace. (Wear points are near any sharp edge.)

Try a Jeep forum or two.

After you fix this problem, sell it! Wrangler transmission-failures are legendary.

It’s most likely either a bad coil pack on the 4.0l 6 or the Cam position sensor. The Cam sensor is more common, but when I had that problem it stopped and never started again. When I had the coil pack problem it behaved like you are describing. I have a 2001 Cherokee with the 4.0l 6, same engine as the Wrangler.

I need to correct myself I meant to say crank sensor not Cam sensor.

Ping to self.

I own a 1967 Jeep Grand Cherokee. Did the same thing. Three sensors were out.

Will get back to you later today when car expert comes home.

Is there a fuel pump in the gas tank as well on a Wrangler? Some cars have two. It might be the problem.

I never cared to own a Wrangler. I will stick to my no power Willys CJs with a 3 speed. If I get another AMC era, I will take those problems as well over a Wrangler.

Just hold on. ObamaCarCare is coming just after the election.

Start saving thousands now for the premiums.

As others have noted, this sounds like the crank position sensor. VERY common fail point on this engine. You are getting the classic symptoms of one that is failing.

Partial clog in the fuel filter, maybe? Certain G-forces (turning) cause it to block completely?

One thing I forgot earlier. There IS a way to test the crank sensor in Chrysler’s to be sure it’s dead.

The catch, it has to not start for the test to work. Connect your scantool and watch the RPM. If it stays at 0 and the engine is cranking you have identified your problem.

PCM’s do fail, but they don’t fail often. Crank sensors do. The interweb is littered with stories about failed crank sensors.

Start there

Yes, it’s on top of the fuel pump assembly on top of the fuel tank. You have to remove the tank to get to it.
