PURPOSE: An LPG(Liquefied Petroleum Gas) vehicle having fuel supply function using a start key and a control method thereof are provided to prevent the cut-off of fuel supply by unifying an engine start key and a fuel supply control key and to completely burn residual fuel by delaying engine stall. CONSTITUTION: A main relay(6) for supplying power to a controller(1) is connected with an operator(3) opened and closed by a signal generated from a fuel operating unit(2) of the controller having a main relay operating unit(5). A crank angle signal processing unit(20) for processing a crank angle signal of an engine are connected with respective connecting lines(4a,6a,20a). When an ignition key is on, the controller supplies fuel to the engine by operating a start switch. Thereafter, the crank angle signal processing unit ignites an ignition coil depending on the rotation of a crankshaft. Then, the engine is maintained in the idle rotation state. The circuit of the main relay is cut off. Thus, the engine is stopped.
