Remove the rear seat, thoroughly brush off the area so no garbage can fall in the tank, remove the lock ring, lift the pump up just a bit and shine a bright flashlight into gas tank, and if you can see a lot of very fine metallic shavings in the bottom of the tank, this is a sure bet that the pump has ground itself to pieces, and indeed, the pump has ended its useful life, making replacement warranted. Relacing the fuel filter would also be a good move.
