Now fixed, fitted fuel flow sensor back of pump and pressure relief sensor on common rail
Ran better but not quite right, did the pump learn on launch x431 spent ages trying to get it to successfully complete pump learn, but no joy, then I tried a friends snap on machine it completed pump learn first time van runs a dream.
Thanks to all for your help
And Thankyou Andy for your tips over the phone I am very grateful.
I just need to sell it now was my first van purchase this time round, I am getting back into vehicle trading again
Never use to be this hard.
