ABSTRACT OF THE DISCLOSURE A fuel injection system includes a pump including a pump plunger and electromagnetic means for actuating the plunger against the action of a spring. The electromagnetic means in- cludes a winding which is energised to cause delivery of fuel. First electronic means is provided to cause energisation of the winding when delivery of fuel is required and second elec- tronic means operable to cause de-energisation of the winding. The second electronic means includes a comparator which receives a required fuel signal and a signal from a transducer which provides a signal representative of the plunger position. When the predetermined movement of the plunger has taken place the winding is de-energised to allow the plunger to return under the action of the spring.
