Where is the fuel pump reset switch located?
The fuel pump reset switch, often called an inertia switch, is not in one universal spot; its location depends on the make, model, and year of your vehicle. In many cars it's found in the passenger-side footwell behind the kick panel or in the trunk near the spare tire well, but some models place it behind the glove box or under the dash. Consult your owner's manual or dealer for the exact location.
This article explains what the inertia switch is, how locations vary by vehicle, how to identify common spots, and how to reset the switch safely if it has tripped, including scenarios where your car may not have one at all.
Common locations by vehicle type
Below are typical spots where automakers commonly place the inertia switch. Not every vehicle uses one, and locations can differ even within the same brand.
- Passenger-side footwell behind the kick panel
- Behind the glove box or under the dashboard on the passenger side
- Under the center console or beneath the rear seat area
- In the trunk near the spare tire well or behind an access panel
- Behind an interior trim panel in some hatchbacks or SUVs
Locations vary widely; if you can't locate the switch, check the exact model's owner's manual for the precise spot.
How to locate and reset the inertia switch in your car
Use the following steps to locate (if present) and reset the switch after it has tripped, being mindful of safety and model-specific differences.
- Turn off the ignition and remove the key; ensure the vehicle is safe to inspect.
- Look up your car’s exact inertia switch location in the owner's manual or a service manual for your model and year.
- Visually locate the reset button (usually red or yellow) on the switch in the identified area.
- Press the reset button firmly until it clicks; some models require a brief press and hold (about 1–2 seconds).
- Turn the ignition to ON (do not start the engine yet) and listen for a quick fuel pump prime; if you hear it, proceed to start the engine. If not, wait a moment and retry or check fuses/relays.
- Start the engine; if it runs normally, the reset was successful. If it fails to start or stalls, stop and seek a mechanic's help, as other fuel-system faults may be involved.
Remember: never bypass or disable safety systems, and if your vehicle lacks an inertia switch, its fuel pump is controlled differently—consult a professional if you are unsure.
Does every car have an inertia switch?
No. Many newer vehicles do not use an inertia switch at all; fuel pump control is managed by the engine control unit and other safety systems. If you can't find a reset button, your car likely doesn't have one, and you should consult the owner's manual or dealer for fuel-safety procedures.
Summary: The location of the fuel pump reset switch varies widely by vehicle. Always check the owner’s manual or contact the dealer to confirm the exact spot. If it has tripped, reset it only as described, and never bypass safety systems. If you still can’t locate it or if the car won’t start after resetting, seek professional help.
