How do you know if the fuel pump is out on your 1997 Nissan Altima Se 4 door?
The best way to see if a fuel pump is working on any vehicle is
to open the gas tank or get as close to the tank as possible. Turn
the ignition switch to "ACC" with out turning on the engine. If you
hear a click and humming, or feel vibration coming from the gas
tank then your fuel pump is operational. Just listen for it and it
will tell you if its operating or not.
