Where is the fuel cut off switch in a 1996 ford f150 pickup?

There isn't a readily accessible, easily identifiable "fuel cut-off switch" like you might find on some machinery in a 1996 Ford F-150. Fuel delivery is controlled electronically, and shutting off the engine is the typical way to stop fuel flow. There's no single switch designed for emergency fuel shutoff.

While there might be an inertia switch (which cuts power to the fuel pump in a collision), this is usually located under the dash or in the engine compartment and isn't intended for routine use. It's not a simple on/off switch.

To stop fuel flow in an emergency, your best option is to turn the ignition key to the "off" position.
