Abstract: The present invention comprises a fuel pump controller having a silicon controlled rectifier (SCR) for supplying a power source voltage to a fuel pump circuit for driving a fuel pump when the SCR is turned on. A timer circuit is also provided for instantly turning on the SCR for a predetermined time period when an ignition switch is initially turned on so as to provide a discharge of fuel into the carburetor before the engine is activated or rotated. In addition, a controller is provided for repeatedly turning on the SCR each time the engine is rotated such that the fuel pump will be driven by rotation of the engine until such engine rotation ceases. By operation of this assembly, fuel is supplied to the carburetor for a predetermined time period before the engine begins to rotate so as to obtain an efficient and quick engine ignition despite the possible initial lack of fuel in the carburetor.
