A fuel injection device having a passage and an on-off valve provided on the return passage and opened when the engine is stopped, and configured to lower the fuel pressure in the fuel supply passage when the engine is stopped.
The fuel pump is characterized in that the on-off valve is closed by an ignition ON signal from a key switch, and a timer means is provided for receiving the ignition ON signal and transmitting a drive signal to the fuel pump for a predetermined period of time from the time when the ignition ON signal is input. fuel injection system for the engine.
