This patent describes a controller for controlling fuel supplied by a fuel pump driven by a fuel pump motor to a fuel injection valve of an engine. This controller consists of: (a) sensors for detecting engine operating conditions and for generating sensor signals corresponding thereto; (b) an input unit responsive to the sensor signals for providing digital output signals corresponding thereto; (c) a microcomputer connected to the input unit for receiving the digital output signals. The microcomputer is operable to calculate a basic fuel injection time period during which the fuel injection valve injects fuel into the engine and a basic motor-drive duty cycle for driving the fuel pump motor to supply fuel from the fuel pump to the fuel injection valve in accordance with the digital output signals; (d) an injector drive unit.
