In the rear of my Cherokee there is a hissing type sound coming from inside my gas tank. This would lead me to believethat this is my fuel pump. I first noticed it when I bought the car but figured it was just a normal sound. Now when accelerating in first and second gear I hear a noise that sounds like a low whinning coming from, I suspect, the fuel pump. Yesterday while accelerating at about 2200 rpm my engine bogged down and choked for about one second before regaining full power. It's a very healthy '92 4.0L H.O. and is very very pampered. What should I look at as the problem? Fuel pump, filter, gas line pinch?, injectors? Any suggestions are greatly appreciated. Thanks ahead of time.

Mike

Thanks a million for the tips guys. I have a feeling that it is either my fuel pump, fuel filter or even just rust in the gas tank that may be clogging my fuel pump/lines.

What do you think are the chances that it could have something to do with my computer or the electronics of the vehicle? I noticed yesterday that if I pump the brakes a few times the engines will climb from idle to about 1100rpm.

Are you sure? It never happened before and none of my other vehicles do it?

Could you elaborate on this for me. Too many parts on these new engines.
