    If there are no codes it's probably an injector problem. If the code is 001347.07 and the filters and fuel system are clean then it may be the suction control valve.

    I'd check the fuel system right back to the tank suction filter and the transfer pump..
    "Start at the beginning" as I often say .

    So you think there's a blockage or damaged hose do you ?

    Hoses degrade over time, dirt could be in the tank, filters could be past their best etc.. If you're changing the filters, make sure the O ring is present / good between the primary filter and the glass bowl. I prefer genuine filters too..

    Hi mate yeah that code just came up 1347.07 everything looks clean so you think it's the suction valve ?

    It's a very expensive thing but so long as you're sure everything else is fine then you could fit one. Buy it on a 'stock order', you may get a discount.. Keep everything clean when you fit it and smear grease on the O-ring sparingly..
