How to Reset Fuel Cut Off Switch (Inertia Switch) on Ford Fiesta
Engine cranks, but it won’t start. Sound familiar?
After being in a car accident, you might end up with you engine unable to start.
You might think that there is some major motor damage or malfunction that caused this, but in most cases you only need to reset the fuel cut off switch which was activated by the impact.
This switch is actually a security measure implemented by car manufacturers in order to shut off the fuel supply in case of car crash, fire or some “bumpy” accident
This is similar to electrical circuit breaker in your home which can be easily reset 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 power supply for the fuel pump if the vehicle is in a collision. This prevents fuel (under pressure) being pumped from the fuel tank in case fuel line is damaged during the accident.
To start the engine after car accident you need to find fuel cut off switch location (car inertial switch) and reset it
I had an accident with my 1.25 ccm Ford Fiesta 2006 and after the crash car would not start. I figured out that there must be some kind of fuel cut-off switch but the problem was that I could not find/locate it! After some research of possible inertia switch location, I narrowed down the potential location to somewhere behind the drawer or glove compartment on passenger side (which is right side of the vehicle on US/EU cars and left side on UK/AUS cars).
Steps to locate and reset fuel cut off switch on Ford Fiesta
- First, open the glove compartment
- Pull out the glove compartment by firmly pressing left side toward inner section
- Look for device with rubber yellow cap on it
- Push the rubber yellow cap on inertia switch
Now put the key in and start the engine. You might need to crank it up a few times before the motor is started. And that`s it. You have just saved at least $50 for the mechanic…
