Fuel pump whining comming from a03 gmc sierra
My fuel pump is very loud. I'm told it is aftermarket but it is fine.
it is the fuel pump because it is located in gas tank normal sound
also, check your power steering fluid levels. The noise you hear is the fuel pump.
The relays have nothing to do with the whining noise, they just complete the circuit and make things work. The whining noise is the fuel pump and that is a common problem with Chevy That noise will not hurt anything, but I would change the fuel filter and that may quite the pump a little. A stoped up fuel filter will burn a fuel pump up.

Each fuel tank has a fuel pump inside them.
