* Inertia Switch (Crash Sensor): This is a common safety feature. It's usually located under the dash, often near the driver's side, and cuts power to the fuel pump in a collision to prevent fires. It's often a small, easily resettable switch. Check your owner's manual for the exact location in your vehicle.
* Fuel Pump Relay: This is part of the car's electrical system and controls power to the fuel pump. This is not a switch you'd manually operate but a component that's part of the overall safety system. It's usually found in a fuse box (under the hood or inside the car, depending on the model).
* Computer Control: The car's computer module (PCM) monitors various sensors and conditions (e.g., engine speed, crankshaft position) and will prevent the fuel pump from operating under certain circumstances, like a stalled engine or during a crash. This isn't a physical switch you can interact with.
To find the inertia switch: Your best bet is consulting your owner's manual. The location varies slightly between model years and trim levels. If you don't have the manual, you can find a digital copy online by searching for "2000 Chevy Venture owner's manual PDF."
There's no single "fuel pump safety switch" to look for; the safety measures are distributed across the vehicle's electrical system. If you suspect a fuel pump issue, it's best to consult a mechanic for proper diagnosis.
