Jeep Engine Stalls Just After Startup
I have a 2000 Jeep Grand Cherokee Limited, 76,000 miles. I had a weird problem today. The engine would start very quickly with no hesitation, run for about 3-5 seconds, and then abruptly shut off. After about 2-3 starts/stops like this, I gave it some gas immediately after starting, to see if I could goose it and make it keep going. No luck. I am NOT a mechanic, but my first thought was some type of fuel problem. Maybe the gas line filter. It then occured to me that the engine was acting **exactly** how the Jeep will act if you use a non-chip (programmed) ignition key to start it. I had done this one time (not aware of the chip need in the spare key) and the engine acted the same way -- quick start/ run 3-5 seconds/ shut off. This happened today. I have now started it several times and it is running without a problem. I would appreciate any comments on what any of you guys think this might have been, and if I am likely to have the same problem tomorrow, etc. Thanks for any help !! --James--- |
Re: Jeep Engine Stalls Just After Startup
If this only happens after it's been sitting for a while like
overnight, then it could be the fuel pressure is bleeding off. If this is the problem you may re pressurize and primes it by turning your ignition to the on position without starting and waiting the five seconds the pump will run and automatically shut off. Do this four or five times and you should have fuel back in your rails again.

Re: Jeep Engine Stalls Just After Startup
Bill, thanks for the tip, and I will try that if it happens again. But, what is the ultimate cure -- a more permanent solution ?? I guess if it only happened once a month or so, then I could just use your method and all would be ok.............. I will see how it goes. I will enjoy any other postings on this, as my wife is now hesitant to drive it for the next week or so until we know what it is going to do. --James-- |

Re: Jeep Engine Stalls Just After Startup
I believe that failure is in the Fuel Pressure Regulator the six
cylinder is pictured at: http://members.cox.net/wilsond/Fixes....html#fuelrail If this happen when it hasn't been sitting then it could be the Crankcase Position Sensor, talked about in this old Cherokee site: http://www.off-road.com/jeep/cheroke...tdcsensor.html God Bless America, ßill O|||||||O mailto:-------------------- http://www.----------.com/ James Nipper wrote: > > Bill, thanks for the tip, and I will try that if it happens again.

Re: Jeep Engine Stalls Just After Startup
Sounds like your not getting fuel. The ecm primes the fuel system when you
first turn the key on (runs the pump for 2 sec) then shuts off. once the engine starts and is running it turns the pump on continously once it "sees" oil pressure, and various other signal from other sensors. the engine can run for a few seconds on this initial "prime", then shut off. one problem i have come across on the same vehicle as yours was a faulty ignition switch not supplying power to the main relay causing the vehicle to stall after start-up. are all of the guages/lights on the dash functioning when it stalls? as suggested , check ecm codes. what you might try is to get somone else to try starting it while listening for the fuel pump. you can do this by putting your ear near the fuel tank and listening for a hissing/humming sound or by removing the fuel filler cap and listening there. see what happens first, either the engine stalls and the pump runs for a second after or the pump stops and the engine stalls.

Re: Jeep Engine Stalls Just After Startup
My 18 year old son did that trick about ignition on / ignition off 3 times to get the error code. It came up with P1685. We looked this up, and the culprit is The engine controller has received an invalid key from the SKIM. SKIM is the Sentry Key Immobilizer Module. As I had commented in my post, it was acting just like it did one time right after I bought the car 4 years ago, when I had a regular key (no chip) made and tried to start the car. For now, I am hoping that it was just a minor glitch, and will not happen again. I do thank everyone, including Bill, Doug, and Shawn for their helpful info !! Getting the code was a good tool. --James-- |

This just happened to my wife's 99 Limited (73K mi) on Friday. I would

Re: Jeep Engine Stalls Just After Startup
This just happened to my wife's 99 Limited (73K mi) on Friday. I would
believe the fuel pressure thoughts, the CPS was just replaced.

Re: Jeep Engine Stalls Just After Startup
I got some electrical contact spray and did this today. So far it
starts consistently and idles at about 500, but the idle is kinda choppy. It fluctuates +/- 100 RPM or so. It doesn't sputter per se, it just kinda sweeps up & down on the tach. I also got some throttle body cleaner and a toothbrush and cleaned the Idle Air Pasage and both sides of the butterfly and the inside of the throttle body cylinder. While it didn't enjoy starting immediately after spraying the cleaner inside the throttle body, I wiped it out with a clean rag and after one start things were ok. What I'm wondering is what the specs say the idle should be. If you're just joining us, it's a 2000 Cherokee Freedom 6 cyl 4.0. Thanks!

Re: Jeep Engine Stalls Just After Startup
Well, the fix didn't last long. In fact the problem is occurring on a
more consistent basis now. I haven't had the battery tested, but the eye is still green and I have NO starting problems or any other problems related to the electrical system. The battery isn't pulling an abnormal from the alternator or anything. It's just this lack of idle. I have determined that if I drive with 2 feet just long enough to get to the end of my block (100 yds at most), it doens't stall. I can also sit there with it in gear and my foot on the break and rev up to about 2500, I'm good to go too. It seems that I have to put it in gear and give it some RPM and I'm ok. Does this sound familir to anyone? Can anyone suggest a fix? 2000 Cherokee Freedom Straight 6 - 4.0L Automatic On Wed, 04 Aug 2004 22:26:38 -0700, Chuck Rowe <none@fakeisp.com> wrote: >I got some electrical contact spray and did this today.
