Can anyone point me in the right direction,iveco say replace high pressure pump,the daily is a 2001 35s11 van which is suffering from intermittent difficult starting,injector light flashing,diagnostic scan code 1631 says fuel pressure too high,can anyone shed any light on whether this could be a regulator fault or as iveco say a pump fault,is it worth cleaning out the filter within the regulator or would this produce low pressure fault if partially blocked |

Hi, A clogged regulator creates too much pressure. Symptom is hard starting, uneven running of the engine, diesel knock, etc... Try to clean the regulator. |

It is behind the high pressure pump, oriented towards the cabin, and it has a black connector. You need a 30 Torx soket to remove the two screws. Take care do not lose the gasket. You should clean the head of the regulator, which is a very fine sieve, with brake spray and then with compressed air. |
