ive got a diesel vectra it will run for around ten miles then the ecu light comes on and it will cut out and wont start for around an hour ive put a feul pump in so there is a continuios fuel supply and the fuel is right to the pump but it wont fire up . WHY ??????
The fuel flow through the injection pump is controlled by the engine management system. You need to have the system connected to diagnostic equipment to establish why the 'ECU' light is coming on.
