After the vehicle sets for about an half hour it acts like it is not getting fuel where is the fuel pump and fuel filter located


Unfortunatly thee fuel pump is in the gas tank. The fuel filter is against the frame right about under the back of the driver seat.

My 1995 GMC jimmy 4x4 just stopped running. Had it towed home. mechanic told me it was a fuel pump. just changed fuel pump and sending unit. Tried to start and will not fire. Put some gas in intake and...


Only one question.....was the fuel filter replaced? On a jimmy the filter is usually mounted to the rail up under the passenger door on the drivers side. Sounds like there is some sort of obstruction that is preventing fuel from making it from the fuel tank to the engine. I would have thought that the mechanic would have replaced the fuel filter first thing, so maybe it has already been done. Only you and the mechanic know the answer to that one. Good luck with your problem.

Fuel pump not pumping


You can Hear fuel running? Where in the tank? If so then it sounds like the fuel pump dettached from the supply line inside the tank.
