Default Whiny Fuel Pump

Guys, my 05 emitting some kind of whiney sound when the engine is running. I think it may be the fuel pump, and its pretty darn loud. I had this problem a while back and the sound is off and on. Does anyone here ever had this experience ?.. Im taking it in in a few days to have it checked out and I thought I ask the forum first. Thanks.

Does the sound come from in front of the left rear wheel? That's where the fuel pump is, and where it's noticeably loudest. If the sound is coming from up front it's something else.

DJackman,

I'm sorry you have been experiencing a whining noise. Please keep me informed on what you find out from your dealer?

The sound comes from sewhere in the middle. Its pretty loud in the cabin. And i can change the whiny tone when i flip the power window switch.

It makes noise when you run the power window with the engine running? It sounds like you're describing alternator noise in the speakers.
