Where is the fuel cut off switch located on a 2002 Chevy Avalanche?

There isn't a readily accessible, single "fuel cut-off switch" like you might find on some equipment or older vehicles on a 2002 Chevy Avalanche. Fuel delivery is controlled electronically, and disabling it requires more involved methods. There's no simple switch to flip.

To stop fuel flow in an emergency, you'd need to disconnect the fuel pump relay or the fuel pump's electrical connection itself. However, these are not easily accessible and require some mechanical knowledge to locate and safely disconnect. This should only be done by someone experienced with automotive electrical systems. Improperly disconnecting these could cause damage to the vehicle or even injury.
