Your going to have to do some testing & get back to us
only if you have vehicle experience eg: work on your own vehicles

I would check fuel pressure with a gauge & possibly see if that
info is avail on a scan tool

You may have a failed fuel pump
You can cycle the key & have someone listen for the pump

next you check for spark

Most people look for the least expensive proble first, which for some is a good thing but after you check/replace, trial/error check, you will not only have waste time but money. In the JGC's for about 1997 to 1999 for sure, the problem 80% of the time, if not higher, is the Computer. It can be very costly, if you go to the Dealer. E-Bay, if you can find a reputable Seller is the Best way to go. Very, Very Important, be sure to match the Number on your computer to the ne/used computer you Purchase. Number for Number, Letter for Letter.


Location: On the Fire Wall under the Hood on the Passanger side. In some case's It is a Loose conection, Shortage in the Harness or Corrosion on the connectors. You can sometimes test it by Tapping on it while the vehicle is running. It will either stutter or shut off. Do this with a rubber hammer is possible. Do not Bang on it Hard as to cause dents.


Some symtoms are:


1 Skipping Engine

2 Misfire/Backfire

3 Hard to Start, Especially on rainy days

4 Will run only for short periods, 1 Min. to 1 hour or longer. May even run for a Week or longer.



To test your Fuel Pump. Find the Fuel Rail under the Hood on the Engine. Most likely on the Driver's side. Please Wear Gloves & goggles and do not Smoke. On the Rail you will find a Valve Stem like you have on your tire. Remove the cap, depress the small stem, while someone turns the ignition forward. Do Not Turn the engine over. If you have a strong stream of fuel comming out, the pump is probally okay. (About 89% accurate). 7 out of the 10 Jeeps I have worked on Needed the Computer.

My 92 Cutlass Ciera starts and drives very good for about 30 minutes, then it dies.


The gas cap may be the problem; when its vent is blocked it builds vacuum in the tank and stops the gas flow. Try releasing it or replace it.

I have a 1989 Ford f150 drive for about 30 minutes it dies out or stop and want crank for about an hour


I would unplug the gas cap when it stalls; if you hear a hissing sound, change the gas cap, because it builds up a vacuum in the tank.

After hot engine wont start and smells like gas


Most likely causes are bad engine coolant temp sensor OR leaking fuel injectors. Bad engine coolant temp sensor will give computer false reading and computer provides wrong air fuel mixture. Leaking fuel injectors will load the engine with raw gas--just like flooding it. Try pushing the gas pedal to the floor and holding it there when cranking when hot. That forces the computer into "clear flood" mode and it shuts off the injectors. If it starts up with pedal down, that would be a sign of leaking injectors.

1991 Camaro RS v-6 will start but dies almost immediately


Keep it simple and replace the fuel filter first, if thr fiiler has not been replaced within 30,000 miles or 1 year. Then it's a good chance that it's going to be the fuel filter.

1995 BMW 540I starts well cold, then dies out after getting to normal operating temperature. Usually will not restart until cools for a long time..cranks but won't start....Jack


I would check the fuel pressure just after starting and again after 10-15 minutes (or before it dies). Sounds like a fuel delivery problem. Could be a stuffed up filter, or the fuel pump could be dying. I had a Volkswagen some years ago and it had two fuel pumps, a large one up in the engine bay and a small "helper" in the gas tank. The one in the gas tank was bad but the bigone was fine, so I'd start the car normally, drive for about 20 minutes, then the car would die and not want to start again until it had cooled off. Maybe you have the same setup.
