i have a 2000 4.2 turbo gu ute. when i start it cold it runs rough (missing i think) and blows a heap of white smoke. as soon as i drive off it clears up and runs smooth, i replaced the glow plugs and it didnt heap.... any ideas??

That sounds like a classic Glow Plug Issue

Are you getting enough volts at the glow plugs to heat em up.

Have you tried giving it more time before you try to start it, even if the Glow Plug Light goes out.

Mine was doing a similar thing recently. Was told different things by different diesel mobs ranging from IP, injectors, fuel priming hand pump cracked and getting air, fuel filter and timing issue. Had it re-tuned and timing was out and it has fixed the problem.
