Possible Fuel Pump Failure

Yeah .. check the filter, could have some crap in it which is closing off the line under load then clearing up when idling or stopped.Rosco

Double yeah! to the filter check mate.

However, make sure you check the whole line as I have had three personal episodes with blocked filters and they all exhibited exactly the same symptoms as you describe.

However in two of these cases changing the main/usual/visible filter did absolutely dick all as one of the vehicles had a factory fitted second filter cunningly hidden externally up in a rear wheel arch, and the other had a second filter ( bleep y little ryco) fitted by an unknown, but 'well meaning' service mechanic at some point in time.

That was well disguised as well.

As no one knew about them they were never serviced and yep! chock a block with all sorts of crap.

Just a thought that may help you before splurging on a new pump.
