Low power

On the side of the lift pump, there should be a lever. If the resistence is low, then the pump could be us.
You could try putting an electric pump in to see if its any better/to confirm that your lift pump is u/s.

For the low power problem: Check the intercooler & turbo pipes for holes, splits and delamination on the inside. Make sure you can hear/feel the turbo cutting in. It's also worth checking the small pipe that runs from the turbo to the top of the injector pump for splits, as this will stop the injector pump going to full fuel as your rev increase, it'll feel like the turbo isn't working!
Try cleaning the intercooler as well, that makes quite a difference if it's not been done for a while!
Starting problem, lift pump or injectors would be the first place I'd start (as suggested above).

checked the pipe from turbo,its ok,checked the lift pump,the lever on the side doesnt seem to doin much,it moves up and down but theres not much resistance at all,when you press the lever down is it supposed to come back up?it just seems to waggle around,taken the sedimenter off and was reasonably clean.......help

You may need to turn the engine a bit more as the pump operates on a cam. It may be in the depressed state.
Tyke:
Would do as Budgie says and check the intercooler, not just the pipes, take the element out and give it a good clean and flush out.
Did my intercooler last weekend as the motor was starting to feel tired.
Has made a proper difference . . . . . revs clean and pulls well again now.
