All modern fuel injection cars are equipped with an inertial fuel cut off switch that shuts off the power supply for the fuel pump if the vehicle is in a collision. This prevents fuel from being pumped in case of the fuel line damage during an accident.Mar 29, 2021
The inertia switch is located behind the trim on the left-hand side of the vehicle, forward of the front door post, below the fascia. A finger access hole in the trim allows the driver to reset the switch.
The switch is called an inertia switch and is designed to shut off the fuel pump supplying gasoline to the fuel injection system in an accident.

if it tripped,then the button will pop up and all you need to do is push it back down until it clicks/stays down. it’s rare for the inertia switch to fail,but possible.

They typically dont go bad.
The only time the inertia switch should trip is during a collision. However, there are other occurrences that can trip an inertia switch, such as a blown tire or simply hitting a pothole in the road.
Can an inertia switch reset itself? A good inertia switch should trip completely on a collision only(sudden stop or airbag deployment), so engine wouldn’t restart without a reset. And a good switch wouldn’t trip by being towed or hitting a bump, nor reset itself, so you could have a bad switch.
The design of the fuel pump inertia switch causes it to turn off the fuel pump if a vehicle is involved in an accident. However, in certain incidents such as a blown tire or hitting a pothole in the road, the switch has the potential to trip. A sudden stop or change in direction activates the switch.
The inertia switch for a 2012 Ford F-150 truck is going to be located on the passenger’s side in the front of the vehicle. It will be in the kick panel and You’re going to need to remove this panel using a pry tool to access it.

“Gas pump nozzles have a device in the end that when gasoline runs back up into it, it turns off the fuel flow.” … So, gasoline rushes back up your car’s fuel filler tube, toward you, instead of into the tank, hits that sensor hole on the nozzle and shuts off the pump before the tank is full.
A Stop solenoid is used to cut the fuel supply to the engine when the ignition is switched off. Stop solenoid fits into the diesel distribution pump and can be a cause for diesel systems to fail. When the solenoid is turned on the plunger pulls the valve which allows fuel to pass through.
Fuses are over current protection devices which means that you either have a short to ground (possibly intermittent) somewhere in the circuit or enough added resistance in the circuit that the current drawn by the pump is enough to blow the fuse.
Most fuel pumps will produce just a quiet hum when they are running smoothly and they are not damaged, but a very loud whining noise indicates a problem with the fuel pump. This bad fuel pump can throw a check engine light if not fixed in time.
A fuel gauge that only reads full may be caused by a faulty fuel gauge resistor sending the full voltage to the fuel gauge at all times. … Another issue may be a defect in the wiring from the fuel sending unit to the fuel gauge causing a shorted signal, or a bad ground wire to the grounding terminal.
The 2014 Ford F-150 does not have a fuel cut off switch at all. It has what is called an inertia switch which will be activated if there is ever an accident. This will cut off the fuel from the pump to make sure that it does not continue to spray and potentially cause a fire.
