A fuel injection system which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine which includes an air flow rate member for actuating a metering and distribution valve, a flushing valve is disposed in an outlet line leading from each injection valve to a return flow line open when the engine is turned off and immediately after actuation of the ignition switch of the engine, enables a return flow via the outlet lines of the fuel flowing through the fuel supply line and the metering and distribution valve assembly to the injection valves until an electromagnetic valve drivable by a time control element opens a pressure line to a pressure chamber of the flushing valve, and the pressure prevailing in the pressure chamber opens a diaphragm connected to the movable valve parts of the flushing valve in such a manner that the flushing valve closes. Simultaneously with the opening of the electromagnetic valve, the electrical circuit of the starter motor is closed, so that after the preceding filling with fuel of all the lines and assemblies of the fuel injection system with fuel, a more certain start of the engine is assured.
