Best Answer

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.
