* Inertia Switch: This is a safety device designed to cut off fuel in a collision. It's typically located under the dashboard or in the engine compartment, often near the fuse box. It usually resets manually with a button. This is your *best bet* for interrupting fuel flow in an emergency. Look for a small, usually red, switch with a resettable button or lever. Check your owner's manual for its exact location.
* Computer Control: The Powertrain Control Module (PCM) manages the fuel pump based on various inputs, including the ignition switch, engine speed, and various sensors. If the engine isn't running, the pump is generally off. The computer can also shut it down if it detects a problem.
* Other Safety Interlocks: Other safety systems might contribute, preventing the pump from operating under certain conditions.
In short: You won't find a simple "fuel pump off" switch. The inertia switch is the closest thing to what you're looking for, and its primary purpose is safety after a collision. If you need to shut down the fuel supply for any other reason (e.g., repairs), disconnecting the fuel pump relay is the more reliable method but requires some mechanical knowledge. Consult a repair manual or a qualified mechanic for the location of the relay.
