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 !!

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.

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.

Any number of things could be doing this. From a simple bad battery ground
to sensor failures.

Pull the engine codes and let us know, ok.

By the way, pumping the gas or "goosing it" only works for carbureted
vehicles, doesn't do squat for fuel injected ones.
