ABSTRACT:
A starting system of an engine according to the present invention comprises an electromagnetically-operated fuel resupply pump for supplying auxiliary fuel to an intake passage of the engine, and various detectors for detecting the operating conditions of the engine, e.g., engine speed, temperature of engine cooling water, drive of a starting motor, etc., and a control circuit for controlling the drive of the fuel resupply pump in accordance with signals from the detectors. The control circuit is partially formed of a microcomputer, which controls the pump so that a pulse voltage is applied to a solenoid of the pump for a longer time when the engine is in a cranking state than when the engine is in any other operating state.
