These pumps are dc motors and when they fail they will not turn or make a noise.If you can hear it then it most likely is pumping.Remove the pump from the tank and make a couple of jumper wires and see it if it will pump water.If you look down into the tank you will see a plastic well the pump/sending unit sets.There must be enough fuel to cover the bottom of this area inorder for the pump to work.Just cant help but think you don't have enough fuel for the pump to pick-up.Go to the service manual at this site and find the section on fuel systems and there you can find the proper way to test the entire system.It really takes the guess work out.Good luck and keep us posted.
