HDI hunting problem.

[darrenjlobb]

All fixed...

Spent half the day farcing around with it...in the end just got pissed off and decided to just try swapping the HP pump..given it takes no time really just belt off / pump and belt back on, Had a used one kicking around, so swapped it over, turned the key..purrs like a kitten...So all of that over a HP pump... had already tried swapping the FPS, FPRS, 3rd piston cut off part, swapped injectors in the morning, swapped engine loom, but was just the pump.

Still dont really understand why, as pressure was up around 290bar at idle, and it drove with full power...just ran like a sack of crap...but seems to be spot on now...so will know for the future anyway.

Thanks for all the help!
