Many vehicles available today come with fuel pump shut-off switches. These devices are essentially circuit breakers that sit inside you car’s airbag control module’s inertia switch, which is supposed to trigger when the vehicle comes to a sudden stop. This safety feature is intended to shut the fuel pump off in the event of an accident, but can sometimes be triggered by a pothole or even by sudden brake application. These switches are generally designed for a quick reset, but some models may require a more involved approach.
Locate your car’s inertial trigger or airbag control module. You owner’s manual should give the exact location, but if it doesn’t try looking inside the center console, under the front seats, behind the glove compartment or behind the driver or passenger-side kick panels. These are the trim pieces just ahead of your front doors where your foot typically brushes.
