Hello all, wondering if you could give me some advice? Car stopped whilst driving on motor way, called RAC who connected car to computer and indicated possible diesel pump fault. Car towed to garage who again indicated diesel pump. Garage sent off pump to company who replaced chip board (ecu?) tested working and sent back. Garage fitted and is still giving me the same issue of not starting. Engine is turning but failing to start? Bit worried as the pump to be sent off was not cheap (however cheaper than a brand new one) Spoke to garage and they are scratching their heads as to why this fault is here? Any ideas????
