How to tell if fuel pump is bad on a 2001 for Taurus?
Park the car is a quiet location and turn the ignition key on but do not start the engine. Listen carefully for the sound of the fuel pump. It will run for a few seconds and then shut down which is normal. If you do not hear the pump, either the pump is bad, the fuse is blown, or the fuel pump relay is defective. You may also hear the pump and it can still be pumping with so low a pressure as to be defective. Make sure your problem is not a clogged fuel filter. Replace the filter asap. If the car has over 100,000 miles on the Odometer you probably need a new pump, especially if you have neglected to replace the fuel filter every 50,000 miles. A clogged fuel filter will burn a fuel pump up very quickly.
