2004 3.0 V6 Supercab EDGE - Whine
I have a whine noise coming from the back of the cab. It is there when sitting still with engine running. It's pretty loud. I think it is the fuel pump and here's why:
When I turn the key to run (but do not start) I hear the fuel pump prime and then when I start the truck the noise (whine) comes from the same area. When driving the whine is there continuously and does not change pitch.
Truck has 80,000 miles and I have no idea of the history or what had been done to it, but it looks bone stock. It runs like new.
This whine is bugging me. If I play the CD loud, I cannot hear the whine. But sometimes I like to just hear quiet, which I can't with this whine.
If it is the fuel pump, how hard is it to replace the pump? What about the fuel filter? Could a clogged fuel filter cause the pump to whine?
