Have your O2 sensors checked, with an OBD2 meter, and see if they are functioning, if not replace them. O2 sensor is located in the exhaust pipe between the motor and the catalytic converter. The front O2 sensor runs the engine and the after cat converter monitors the cat converter.

Are you positive its the fuel pump? Have you tried running the pump with the return line off to see if it pumps fuel? They don't always have to make a noise.
