What is Fuel Pump Emergency Cut Off Switch?

This device is analog to an electric circuit breaker, but only for fuel, not electricity.

Many vehicles come with a fuel pump shut off switches. The inertia switch is a security measure implemented by car manufacturers to shut off the fuel supply in case of a car crash or accident where a vehicle comes to a sudden stop instantly.

How to Reset Fuel Pump Shut Off Switch

Similar to an electrical circuit breaker in your home, you can reset it by pushing the button or pulling the leverage down.

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.

To start the engine after a car accident, you need to find fuel cut off switch location (car inertia switch) and reset it

I had an accident with my 1.25 ccm Ford Fiesta 2006, and after a crash - the car would not start. At first, I thought that there is some major motor damage or malfunction that caused this. Then I figured out that this might be due to activated fuel shut off switch, but the problem was that I could not find it!

After some research on possible inertia switch location, I narrowed down the choice of potential places. One of those places was somewhere behind the drawer/glove compartment on the passenger side (which is the right side of the vehicle on US/EU cars and left hand on UK/AUS cars).

Emergency Fuel Shut Off Switch Location on Other Cars

On Ford, Peugeot, VW, Citroen, Vauxhall, Subaru, Renault, Toyota and Mazda, inertia switch location is usually on one of the following two hidden places:

  • Behind or below glove compartment, sometimes hidden under the carpet;
  • Under side-panel located next to the drivers' door;
  • On the driver side, between the footrest area and door, sometimes hidden under the carpet.

After finding the switch, it is easy to reset it with one push of a button.

Now put the key in and start the engine. You might need to crank it up a few times before the motor starts.

And that's it. You've just saved at least $50 for the mechanic...
