To provide a fuel feed control device capable of suppressing noises due to the opening/closing operation of an opening/closing means in a high pressure fuel force-feed means with a forcing means for pressurizing a fuel, which is arranged on the downstream side of a low pressure fuel force-feed means for force-feeding the fuel to a fuel injection device, and the opening/closing means for opening/closing the feeding flow passage of the fuel fed to the forcing means.
This fuel feed control device controls the high pressure fuel force-feed means 1 provided with the forcing means 1p for forcing the fuel force-fed by the low pressure fuel force-feed means, which is arranged on downstream of the low pressure fuel force-feed means for force-feeding the fuel to the fuel injection device, and the opening/closing means 1s for opening/closing the feeding flow path of the fuel fed to the pressurizing means. When the operating conditions of an internal combustion engine satisfy preset prescribed conditions, the opening/closing means is stopped in an open state, and the fuel is fed to the fuel injection device by the low pressure fuel force-feed means without an increase in pressure of the fuel by the forcing means.
