Where is the fuel shut-off switch on a 1991 Buick Regal?
There isn't a readily accessible, easily-located fuel shut-off switch on a 1991 Buick Regal like some older vehicles had. Fuel delivery is controlled electronically, and there's no manual switch for immediate shutoff in the event of a crash or fire. The fuel pump will stop when the ignition is turned off, and the system will generally shut down in the event of a major impact.
