Question about 2003 Ford Expedition
When you turn on key on is the pump suppose to hum or just click ; I also checked shut off switch and it was not tripped
That's it, that's the definitive answer-it clicks in the tank? The pump is bad, and will need replacing. It should turn on for about 2 seconds to pressurize the fuel line and system with key on-that is the hum you refer to.

The reason car batteries do that is because the battery only runs your accessories and starts the car. The alternator runs the vehicle and charges the battery once it is started. If the battery is failing the charge provided by the alternator runs your accessories and the leftovercharge is displaced into the dead battery.

try resetting the inertia switch located on drivers side way up under the dash,with a red button on top,maybe you kick it or hit the body hard enough to kick it off,also check the fuel pump relay under the hood drivers side ,i think brown and black relay box over wheel( inner fender)..and check the fuse,and new fuseable link
