fuel pressure was 179 to 230 bar, i dont know why df137 as engine had no error codes when in other van

It looks like you have a fuel supply problem to the high pressure pump

How quickly does the fuel pressure rise when cranking?

Try giving it some brake cleaner to see if it will run and help built the pressure up

also try using a can of diesel and give the pump your own a direct feed

non genuine fuel filters are bad for letting air enter the system

Thanks for your help,today i replaced the wiring loom in the engine bay to try to eliminate frayed wire i also removed and cleaned the earth strap and even added another earth also replaced the fuel filter.Today when i looked at live data while cranking the engine the fuel pressure was bouncing all over the place from 7 bar at lowest and 117 at highest.When hand priming the fuel you can hear the return pipe sending fuel back to the tank.I dont know if Autocom is misreading fuel pressure as there is no reason why it would fluctuate so much.Anyway i will try what you have suggested and let you know
Thanks again
