I have a 98 Jeep Grand Cherokkee 5.9 limited. When I am driving it it feels like its bucking and when I am at a red light it starts to idle rough then it stalls out. I have to put it in nuetral and get the rpms up in order to keep it running. I have been told that my fuel pump could be on its way out. Does anyone know what it could be??

Probablly one of your sensons Crank position sensor or Throttle position sensor. The expets here will chime in soon.

Could be the pump, but check the sensors to. I had a similar problem with mine. Turned out to be the IAC. Its located in the back of the throttle body. pull it out and clean it up a bit. You can push the plunger in, but DON'T PULL IT OUT! If it doesn't move, its no good and needs to be replaced. You might also purge the fuel rails, just get a cup or something to catch the fuel that comes out. Push in the pin really easy so it releases the pressure slowly, there could be a small air bubble in there. How much gas is in the tank?

Thanks guys I'll try this out first before getting a new pump. Its been driving me crazy for weeks now trying to figure out what could cause it.

I have about a half a tank of gas
