Hi we have this car in and its not firing on number 5 cylinder,coil leads and plugs been replaced, have traced it down to injector not opening, removed and had it tested all ok, swapped with another cylinder and works ok there,found that the wire to injector is not switching just got 2 lives,have traced wires back to ecu and all ok.sent ecu to BBA-REMAN for testing and they say its ok, im not convinced. can any one shed some light on where it gets info of what injector to work is it from coil. crank sensor or just the ecu. Many thanks Paul
