An electronic timing system for controlling the injection angle of a fuel pump, comprising an input sleeve (12), an output drum (36), an intermediate drive sleeve (30), a drive plate (60), a drive yoke (76), and a stepper motor (90). Drive sleeve (30) includes a pair of radially inwardly and outwardly projecting drive pins (32), and drum (36) and input sleeve (12) both include helical slots (38 and 16), respectively, through which pins (32) project. Vertical movement of yoke (76) causes axial movement of drive plate (60) and drive sleeve (30), which causes a relative rotational adjustment of angle between input sleeve (12) and output drum (36), for retarding and advancing the timing of the fuel injection system.
