Instead, fuel delivery is controlled by several interconnected systems:
* Inertia Switch: This is the closest thing to a fuel cut-off switch. It's a safety device designed to shut off fuel in a collision. It's usually located in the passenger compartment, often under the dash or near the fuse box. It's a small, usually red, button or switch that needs to be reset manually after a suspected activation (you'll need to check your owner's manual for the exact location in your specific Explorer).
* Fuel Pump Relay: This relay controls power to the fuel pump. Removing or disabling this relay effectively stops fuel flow. You'll find this relay in the underhood fuse box, but again your owner's manual will have the exact location. This requires some mechanical understanding and is not a simple on/off switch.
* Fuel Pump Circuit Breaker: Similar to the relay, this is a safety device that interrupts power to the fuel pump in case of an overload or short. It would need to be checked or replaced.
* The computer (PCM): The Powertrain Control Module ultimately manages fuel delivery based on various sensor inputs. A malfunction here *could* stop fuel flow but it's not a switch that you can consciously use to turn off the fuel.
In short: There isn't a simple "fuel cut-off switch". To stop fuel flow, you need to either disable the fuel pump relay or deal with a potentially more complex computer issue (which isn't recommended unless you're very familiar with automotive systems). The inertia switch is the most accessible and intended for a safety cut-off in an accident.
