Berlingo 2.0hdi (June 2002) 90bhp got a bad misfire, sounds like running on 3 , has siemens injection system, had new injection pump 8 months ago, have changed fuel filter, we seem to have very little pressure out of the high pressure side of the injection pump to the common rail, have removed feed pipe from common rail , seem to have very little fuel delivery out of pump when cranking.Could it be electronic problem with pump, ie partially opened solenoid, or could pump be faulty.
