ABSTRACT:
A detector for detecting the operational status of one or more fuel pumps in a fuel system of a vehicle, the system comprising an accumulator volume for storing high pressure fuel, one or more injectors arranged in fluid communication with the accumulator volume and one or more high pressure fuel pumps arranged in fluid communication with the accumulator volume so as to supply high pressure fuel thereto, the operation of the one or more fuel pumps being controlled by a filling pulse signal from a control means, the detector comprising inputs for receiving data representing at least one current system parameter; processing means arranged to compare the at least one current system parameter against one or more predetermined system parameters in order to identify the operational status of the one or more fuel pumps.
