How do you reset the fuel shut off switch on a Ford?
If your Ford is equipped with an inertia (fuel shut-off) switch, you reset it by pressing the red reset button until it clicks. If your model doesn’t have this switch, there is nothing to reset.
This article explains what the inertia switch does, where to find it on Ford models, how to reset it safely, and what steps to take if resetting doesn’t solve a no-start condition.
What the inertia switch does and why it matters for Ford
The inertia switch is a safety device designed to cut power to the fuel pump after a significant impact or crash. Some Ford models, especially older European-market vehicles and certain configurations, include this switch as a simple, manual reset mechanism. Many modern Ford cars sold in North America do not use an inertia switch, so there may be nothing to reset in those vehicles.
Common locations for the inertia switch on Ford vehicles
Location varies by model and year. The following spots are commonly referenced by Ford owners, but you should verify with your owner’s manual or a dealer for your exact vehicle.
- Under the dash on the passenger side, near the kick panel or glove box area.
- Behind interior trim in the passenger footwell.
- In the trunk near the fuel pump access panel or wiring harness (in some wagons/hatchbacks).
- In a few models, near the engine bay firewall or power distribution area (less common).
Because locations can differ significantly by model and year, always consult your owner’s manual or contact a Ford dealer if you’re unsure where to look.
How to reset the inertia switch safely
Use these steps only if you have confirmed that your Ford is equipped with an inertia switch and that the switch has tripped. Ensure the vehicle is parked on a level surface, with the ignition off and the keys removed before you begin.
- Locate the inertia switch and inspect the red reset button. If the switch has tripped, the button will often be popped out or recessed.
- Turn the ignition off and remove the key (do not attempt to start the engine during reset).
- Press the red reset button firmly until you hear or feel a click indicating it has reset.
- Return any trim or panels you may have removed and reconnect any wiring or plugs that you moved to access the switch, if applicable.
- Attempt to start the engine. If the fuel system has been reset properly, the engine should start normally.
If the engine does not start after resetting, or you’re unsure about the switch’s location or condition, stop and check the fuel pump fuse/relay and wiring. Do not continue to drive the vehicle until the fuel system is confirmed safe and functional.
What to do if resetting doesn’t solve the problem
If resetting the inertia switch doesn’t restore fuel delivery or the no-start condition persists, perform these additional checks or seek professional help.
- Inspect the fuel pump fuse and relay for damage or failure.
- Check wiring to the fuel pump for loose connections or corrosion.
- Test fuel pressure with a gauge, or have a shop diagnose the fuel system to confirm fuel delivery.
- Consider other starting system components (ignition, crank sensor, and related wiring) if fuel delivery is ruled out.
If the problem remains unresolved after these checks, contact a Ford dealership or qualified mechanic. In some vehicles, the inertia switch or associated wiring may be damaged and require replacement.
Summary
The need to reset a Ford’s fuel shut-off (inertia) switch depends on whether the model actually uses this safety feature. For vehicles that do, locate the red reset button, ensure the switch has tripped, press it until it clicks, and attempt to restart. If the switch isn’t present or resetting doesn’t fix a no-start condition, review fuses/relays and fuel delivery with a professional. Always refer to your specific model’s manual for exact location and procedure.
