Sounds to me as if its the pump timing that is out

Radiotwo - High pressure pump just pumps to the rail - No timing.

Its more than likely electrical, if it was working ok before! any diagnostic codes?

I have the same problem on a 2002 312 CDI.

Van got the usual black death, all the injectors were removed cleaned and one replaced. was running fine but diesel pump on engine leaking badly... changed for a new one.... was running fine, but after a week, its now missfiring, down on power.

Only codes its throwing up are
P2007 and P1482 N14/2

It's starting to do our nut in ... :crybaby2:
