To stabilize a fuel pressure sucked by a high-pressure fuel pump at desired pressure in a fuel injection control system for an internal combustion engine system including an electric low-pressure fuel pump for sucking fuel from a fuel tank and a high-pressure fuel pump for boosting the pressure of fuel ejected from the low-pressure fuel pump.
The fuel injection control system for the internal combustion engine includes: the electric low-pressure pump which sucks the fuel from the fuel tank; the high-pressure fuel pump which boosts the pressure of the fuel ejected from the low-pressure fuel pump; a drive circuit which drives the low-pressure pump; and a control means which controls the drive circuit where a current value is used as a control parameter inputted from the control means to the drive circuit, and the drive circuit drives the low-pressure fuel pump so that the actual power consumption of the low-pressure fuel pump coincide with the current value inputted from the control means.
