I have a MK3 Mondeo 2002 TDDI. The car suddenly died on approach to the lights. The recovery man came and concluded it was the diesel lift pump. After a few knocks the engine restarted and I made my way home accompanied by the recovery breakdown van.
The following morning I travelled about 20 miles and the car died again. This time the car failed to start aftert a number of gentle knocks. I was towed home and the fault diagnosed as the lift pump.The lift pump has now been replaced but the car will still not start. I have noted that there is no power showing at the pump's electrical connections. Is this a relay problem or something else. Your thoughts welcomed.
