Hey guys, having some trouble with the VY V6. Lately when I crank it over to start, it will either fire and then die, or wind over for a few seconds and then stop cranking all together. Turn key off and try again a few times and will finally start. Battery is not that old and doesn't sound lazy. It has new plugs, leads, fuel filter, air filter, I always run it on premium and occasionally run some injector cleaner through it. Once it has started it runs as per normal, no power loss, no miss etc Thoughts? Oh and sometimes it's not doing the above at all, as in it just starts normally first go.
