1999 Pontiac Bonneville fuel shut off switch?

The 1999 Pontiac Bonneville does not have a readily accessible fuel shut-off switch like some other vehicles. There's no switch inside the car or under the hood that's designed for quickly cutting off fuel in an emergency.

To stop the flow of fuel, you would need to disconnect the fuel pump's electrical connection or the fuel pump relay. This requires mechanical expertise and is not recommended unless you are experienced with car mechanics and are comfortable working with the fuel system (which is dangerous due to the flammability of fuel). Improperly disconnecting these components can damage your vehicle and create a safety hazard.

In a true emergency, the safest and most effective way to stop a fuel-related fire is to utilize a fire extinguisher or call emergency services.
