No, fuel does not shut power off to the ignition. Instead, the ignition system is responsible for generating the spark needed to ignite the fuel-air mixture in the engine. Fuel delivery and ignition are separate systems; if the fuel supply is cut off, the engine will stop running, but the ignition system can still be powered on.
Remove the fuel pump relay or the fuel pump fuse.
There is no emergency fuel shut off. The ignition switch just shuts down the Power train Control Module. The fuel pressure and timing of the fuel to the fuel rails at the engine are also controlled by that control module. The only control the driver has over fuel delivery is that of turning the ignition switch on or off, and how much you press the gas pedal. I personnally think that is why we have so many fires during collisions, the pressure is on the line to the engine as long as there is power to the fuel pump which is mounted in the fuel tank.
In the absence of a fuel system shut off as in an alarm system I would suspect a fuel pump fuse, or faulty ignition switch
check fuel pump or ignition system
The ignition module could cut off the fuel supply. The oxygen censor will also cut off the power from an automobile as well.
what kind of car? IF its fuel injected the key turns off the computer, the fuel pump, and the ignition coil
FUEL PUMP SHUT-OFF SWITCH After a collision, if the engine cranks but does not start, the fuel pump shut-off switch may have been activated. The "Fuel Reset" indicator light will illuminate in the instrument cluster. The shut-off switch is a device intended to stop the electric fuel pump when your vehicle has been involved in a substantial jolt. 1. Turn the ignition to the OFF position. 2. Check the fuel system for leaks. 3. If no fuel leak is apparent, reset the fuel pump shut-off switch by pushing in the reset button. 4. Turn the ignition to the ON position. Pause for a few seconds and return the key to the OFF position. 5. Make a further check for leaks in the fuel system. Roadside emergencies The fuel pump shut-off switch is located in the passenger's foot well, behind the kick panel.

There is no fuel pump shut off switch on a Pontiac Firebird. Instead, it has a fuel pump relay under the hood in the power distribution box.
