Thanks for the replies, I've got another pump now - a known working one this time 
but when I got it home realised the max fuel / boost had been adjusted and there was more travel in the accelerator arm than the faulty pump.
I've reduced the max fuel / boost and put the arm back a spline so it is closer to standard settings.
The engine still jumps to 2k revs as soon as it's started along with a lot of white smoke coming out the exhaust. I reduced the cold idle speed but it didn't seem to make any difference.
Any ideas what else could cause the engine to rev so high at idle?
