Fuel Pump

I have a 97 Jeep Grand Cherokee, It started to kind of spit and sputter
Like air in a water hose when you first turn on the water when I drove it. It seemed as if it was not getting gas. It did it after it was driven about 15-20 miles. It is in the 80's here not cold mornings etc. It does it at all conditions. The check engine light came on I took it to the Chrysler Dealership they hooked it up to their computer and it showed a bad CO2 Sensor. We replaced the CO2 sensor and the light went off. Seem to have no problems after that. Next few time driven I would try to pass another car and it would spit and sputter and later die. I would start it and it would run will rough a few minutes, I could go a little father then it would die again. It would do this over and over a few miles then start and run fine. The check engine light never came back on. I took it back to the dealership, they stated the fuel pump was bad. We replaced the fuel pump, they drove it a few miles it died and will not start again. They said it was a bad pump, I dont agree. They say it is getting fire and it just wont start. I feel that I am getting screwed. Please help!!!!!

Same thing has happened to me...with my 94 GC. I replaced the Fuel Pump, Filters, O2 Sensors, battery cables, battery, not to mention the number of times I have been towed. It usually happens if I make a 5 mile trip to the Gas Station.. It is the most frustrating experience imaginable.... Still haven't found the solution... I too await an answer.

Try the AIS motor on the throttle body....(IF V8)

LOOK BACK BY FIREWALL FIND TERMINAL CONNECTOR THAT LEADS DOWN TO CRANKSHAFT SENSOR .UNPLUG IT UPON THE TOP,RECONNECT IT ,IF IT STARTS THE CRANKSHAFT SENSOR IS BAD. [email protected]

I agree that sounds like it could be the problem.
