ran in leak back test at first loads of diesel and air and then virtually nothing but all even amounts to each injector
did not sound like a mecanicl fault removed rocker cover and checked all just in case, all ok and engine timed up correctly
unable to test compression through glow plugs all siezed in and not working but had not been affecting starting
scoped fuel rail pressure sensor looked good scoped fuel pressure sensor correct pattern when ingnition on and when starting (digital pattern unable to tell even when magnified if its changing probably better if measured in frequency but i dont think that on me 3 series scope pico)
as the delphi kit is £600 desided to buy pressure regulator and try it just in case no changed as everthig i could think of tested fit new pump up and running fine
my only concern through this process was my snapon scanner if the converter kpa to bar is correct this car pump should run at 1600 bar 160,000kpa as in my original post with ignition on the post with ignition on ny scanner read 400kpa when starting it read 4600 bar, when the new pump was fitted it went up to 6000kpa before starting and when finely running 25000kpa which is only 250 bar so i think my scanner was never reading it right or the fuel rail pressure sensor is faulty the car goes like a rocket but anyway it fixed and running and ill have to buy the delphi kit
thanks for all your help and ponters much appreciated Phillip
