I've just acquired the above car and am so far very happy with it. It's not perfect with a few bits of interior trim needing re-attached and I've already discovered the absolute joy of changing knackered projection headlamp bulbs!
One issue that's bugging me slightly and one I hope someone can help with is it's not a great starter. It turns over as normal and then gets quicker as if the fuel pressure is building up before it starts. Once going it idles sweetly and performs perfectly. It had a new battery and starter motor fitted just before I bought it and it does start better from cold. I'm assuming I can rule out a faulty preheat system with this being the case. I've changed the diesel filter and added a diesel cleaner, so far with very little improvement.
One thing I did notice whilst idling is that if I put my hands on the injector pipes, no.2 injector does not feels as strong as the other 3. Admittedly it is a pretty Heath Robinson way of checking something but usually the simplest tests are the best. Would it be worth performing a leak-off test on the injectors before carrying anything else out such as cam/crank/coolant sensor checks?
Any help is much appreciated.
TIA

Get it on live data and see if the high pressure hits 30000kpa within a second of cranking, if it doesn't it is most likely regulator related on the HPFP. If it does then it is most likely injector related.
