PURPOSE: A fuel supply apparatus of a diesel engine for preventing engine hunting and a control method thereof are provided to improve the reliability, and to prevent unnecessary consumption of fuel by restricting supply of fuel from inertia of the engine in turning off an ignition key. CONSTITUTION: A control unit receives information on turning on and off an ignition key, and the engine state measured from a crank angle sensor. Fuel is supplied to an injector(11) of a combustion chamber by pumping fuel in a fuel tank with operating a fuel pump(12) according to on-and-off state of the ignition key and the rotational state of the engine. A fuel shutoff valve(30) is formed in the front of the injector to prevent supply of fuel from a fuel line(20) to the injector in turning off the ignition key. The reliability is improved by preventing engine hunting, and the waste of fuel is prevented.
