How will you know if have faulty Fuel Pump? Any symptoms?
Anybody knows what are the symptoms or signs of a faulty fuel pump of an Gen1 Expedition? I'm experiencing weird lost of power with my Expedition.
Pressing down the gas pedal I got no response, it should increase RPM.
Press it to floor that is only time I feel the engine.
Is this a faulty fuel pump? Thanks in Advance.

fuel pump whine
listen for the pump whine with the key on for the first few seconds, then test for fuel pressure, should be 50-60 pis... mine had lack of power also, checked and the pressure was 25 psi truck still ran fine, but lacked power and RPM would go up when the hammer was dropped, but no power behind it. replaced the pump, and filter on the pump as well as inline filter..all is well now.. like a new truck..has better throttle responce and power than my New 08 did

fomoco466, I replaced the pump but still not that happy. There is still loss in power intermittently. I did not replace the fuel filter attached to motor pump. It is already colored yellow. I clean it before reinstalling it but still not responding the way it should be. My guess is I have to replace the filter attached to motor pump. Thanks. Mabuhay!
