    Hi gents, recently had a tandem pump changed also lift pump now experiencing a cold start problem never had a issue before the pumps was changed I've had lots of parts changed since this problem being told it could be this and that, parts changed so far are.
    New tandem pump
    New lift pump
    Battery
    Coolant sensors both of them
    Fuel temperature sensor
    Vacuum pipes
    Turbo boost pipe
    Glow plugs
    Starter motor changed last year,
    Reason for the tandem pump being changed there was oil fuel filter housing also in the tank, this was drain and cleaned out also fitted a fuel filter with a new lift pump, sometimes it starts first time on the button and nextday three or four attempts would really appreciate if someone could help with this matter, it's been on diagnostic with no fault found
    Kind regards Danny

    Even though the the battery and starter motor have been changed, I would still start by having the cranking speed checked.
    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    You would need a diagnostic system that can show the engine speed whilst you crank the engine over with the injectors disabled so that is does not start and keep going for around 30 seconds or more and you need to see a minimum of 280rpm. When done, you would need to clear the injector fault codes you will have generated.
