Another cold starting issue... AU XR6 VCT

[xp_wannabe]

G'day people.

I have a 2001 AU XR6 VCT Ute.

When cold it simply does not want to start, always takes a couple of goes, and it helps if I pump the accelerator...

When hot the engine starts first kick just like it should.

The interesting part is that when cold, if I turn the key to on (without actually starting the engine) and leave it there for about a minute, and then try to start it, the engine fires first time and runs just like it should.

Now in my mind, this means that I am "priming" the fuel pump by letting it run for a minute or so, building up fuel pressure before trying to start.

I mentioned this to the mechanic who rebuilt my diff, and he said that there shouldn't be anything wrong with the fuel pump, because they either just stop working or work fine, there's no in between.. He suggested changing the fuel filter which I did but has not helped..

I have also recently replaced spark plugs, leads, intake gasket, cleaned the throttle body and air filter (K&N), and about 2 years ago I had the injectors reconditioned.

Any ideas?
