Abstract
A fuel pump control circuit includes an SCR for controlling, after turning on of an ignition switch, power supply from a power source to a fuel pump circuit for driving a fuel pump (this SCR being turned on by a gate current supplied from the power source through a first conduction path), a timer circuit for shunting the gate current, which flows into the first conduction path, to a second conduction path when a predetermined time elapses after turning on of the ignition switch, and a current limiting resistor inserted in the first conduction path.
