It's very rare for dirt or water to reach a fuel pump if the filter system has been properly maintained. Check out the filter first.:)

Dirty fuel pump

If water or dirt has got to the injector pump it can cause serious damage and could cause a load of running problems. Is the car runing OK - if not what's happening and how many mies are on the vehhicle. Sounds like its had a poor service history.:)

The symptoms are the following -

- Engine jerking and making a high pitched noise, not all the time, just now and again.

- Loss of power, not to the point of cutting out but it does lose power, and then speed up again.

It feels like theres a blockage or something like that, the engine holds back and then lets go and it goes fine.

I sugggest you take it to a diesel specialist and ask for a quote and then decide if its likely to be cost effective repair as it appears the vehicle has a poor service record, etc.:)
