Where is the fuel pump shut off switch on a Pontiac firebird?

There isn't a readily accessible, dedicated fuel pump shut-off switch on a Pontiac Firebird like you might find in some other vehicles. The primary way to shut off fuel flow is by turning the ignition key to the "off" position. This will cut power to the fuel pump relay, stopping the pump.

Some Firebirds, especially those modified or with aftermarket additions, might *have* an aftermarket fuel pump cutoff switch installed. Its location would be entirely dependent on where the owner chose to place it. It could be under the dash, in the engine bay, or even in the trunk. There's no standard factory location.
