Fuel Pump?

Ugh... this car is draining me!

I'm getting a buzzing sound from underneath in the rear when the engine is running. I can only imagine that this is the fuel pump warning me of impending death.

Anyone ever changed one? Anything I need to know?

Are you sure it's not an exhaust shield band that corroded apart? Just curious, sometimes they sound like buzzing, sometimes they sound like you're killing a Transformer slowly under there...

Have you tried looking for it with an auto stethoscope?

I like it... killing a Transformer slowly. Ha!

The buzzing is almost a whirring sound that stays constant regardless of the engine speed. Definitely coming from some type of motor. I recognize the sound from when my Jetta's fuel pump went. It's the sound of "borrowed time" before a no-start.

The difference is that a VW fuel pump you change from inside the car and it takes a screwdriver and 20 minutes. The Pathfinder requires the fuel tank to be dropped, I believe.
