    Hey,
    I've got a Vt v6 and got a bit of a problem starting.
    When its cold it cranks for about 2 seconds before firing up and might shudder a little bit after it starts, but doesnt do this when it is warmed up.

    So far ive changed the spark plugs, leads, air filter(part of cai), fuel filter, and cleaned the maf sensor.

    It starts pretty much straight away from cold if i prime it 2-3 times(turn key to on, then back to acc, then to on, etc) before trying to start.

    Progressively getting worse aswell.....

    Any Ideas??

    Fuel pump might be getting old?

    Yeah I was thinking it could be fuel pump.
    Might try relay and reg first though
