There isn't a readily accessible, dedicated fuel pump cut-off switch on a 2001 Chevy Malibu like you might find in some racing or aftermarket setups. The fuel pump is controlled by the PCM (Powertrain Control Module) and various safety systems. Disabling the fuel pump would typically require disconnecting the power to the fuel pump relay or pulling the fuel pump fuse. These are not located in a convenient, easily accessible location like a dedicated switch.
To find the fuel pump relay and fuse, you'll need to consult your owner's manual or a repair manual specific to your 2001 Chevy Malibu. The locations vary slightly depending on trim level and options. The relay is likely in the underhood fuse box and the fuse could be in either the underhood or the interior fuse box.
