Abstract
A fuel supply system for an internal combustion engine includes a mechanically actuated fuel pump which has at least one electromagnetically operable valve for controlling an operating parameter of the pump e.g. fuel delivery. A transducer is provided which provides an indication of the position of a moving part of the pump which determines the fuel delivery. The system also includes an electronic control system which determines the current flow to the valve and hence the position of said part. When the pump is manufactured there is created during its testing test data which is stored in a memory which conveniently is secured to the pump. The test data in the memory is utilized by the control system during normal operation of the fuel supply system.
