VT starts weird when cold

[Rob_VT]

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??

my car does it aswell when its cold. its fine, give a few revs when you start it to warm it up a bit

Fuel pump might be getting old?

[Rob_VT]

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

mate that sounds like your fuel pump on its way out.. used to do the same on my old vs commodore before it went caput
