Re: I need to find the fuel safety switch
RESETTING THE SWITCH
- Turn the ignition switch OFF.
- Ensure that there is no fuel leaking in the engine compartment, along any of the lines or at the tank. There should be no odor of fuel as well.
- If no leakage and/or odor is apparent, reset the switch by pushing the reset button on the top of the switch.
NOTE: You may need to pull the carpet down and away from the instrument panel in order to access the switch.

- Cycle the ignition switch from the ON to OFF positions several times, allowing five seconds at each position, to build fuel pressure within the system.
- Again, check the fuel system for leaks. There should be no odor of fuel as well.
- If there is no leakage and/or odor of fuel, it is safe to operate the vehicle. However, it is recommended that the entire system be checked by a professional, especially if the vehicle was in an accident severe enough to trip the inertia switch.
