A fuel control system having a fuel control valve provided in a main fuel path for controlling the amount of fuel for an injection valve, an ON-OFF valve provided in a sub-fuel path and bypassing the main fuel path for controlling the passage of the fuel from the fuel tank, and holding means for maintaining the fuel amount passing through the main fuel path nearly constant. With this construction, when an drastic or abrupt increase of load occurs, the ON-OFF valve is opened and at the same time the amount of fuel passing through the fuel control valve is maintained nearly constant by the holding means, thus preventing the engine condition from being entered into a surging limit.
