the inertia switch is a safety feature if you are involved in a accident it shuts of the fuel at the pump and you should not try to disconnect it nor can I tell you how to do it you will be liable for your actions if discovered after an accident/ what is the problem here ? and what have you done already? no power to fuel pump?(check fuses and wiring)and inertia switch wiring if you are blowing fuses?// fuel pump can be locked up blowing fuses, there is a fuel injection relay, a fuel pressure regulator, a fuel pump circuit open relay, and a fuel tank selector switch, and of course the inertia switch, if you tell me what's wrong I can get you to the results you need otherwise go to rock auto.com and look up your truck and you will see the parts in Pictures so you know what to look for, also if you have a u pull it yard or a regular junk yard you can get this stuff pretty cheap, but new is always better and guaranteed yard parts are risky post back if you want to with progress or problems your having good luck Stephen

I looked at owners manual for 03 ford f150, found this picture for inertia switch location.

Most likely, your inertia switch has been tripped, either due to an accident or a sudden jolt to the vehicle.

You likely tripped the Fuel Shut-Off Inertia Switch.
The inertia switch is located behind the trim on the right-hand
side of the vehicle, forward of the front door post, below the
fascia. Pull open the small panel in the trim to reset the switch.
Resetting the switch
CAUTION !!!:
To avoid the possibility of fire or personal injury, do not
reset the inertia switch if you see or smell fuel.
If no fuel leak is apparent, reset the inertia switch as follows:
Press the button!
If the switch was activated by the accident, you should feel it "click" when you reset it by pushing it.

Happy Motoring!

the sensor keeping it from starting it is an inertia switch. it is a safety feature in case the vehicle rolls or is wrecked etc... it cuts the power to the fuel pump. generally it is located in the trunk of cars or in your case probably near the kick panel on the passenger side. usually has a button to pus to reset

fuel injected cars have a inertia switch that when your in a accident it will trip and shut off power to the fuel pump, you will have to locate it and reset it by pushing the button in look in the trunk or under the dash maybe.

Your vehicle has an inertia switch, which is located on the tow board to the right of the transmission pump. Usually the fuel pump does not shut off except in the case of an accident but you can check it anyway. Being fuel injected, your fuel pump is probably in the gas tank and if there is no power to the wires coming out of the tank, you probably have a bad fuel pump

Very simple, Ford's use inertia switches. They shut the fuel off when you are in an accident. Just call ford and ask for the location of the inertia switch on your vehicle. You just push it in to reset it.

Good luck
