Having issues with initial morning startup. Takes quite a few attempts to get it turning over , then an amount of white smoke. I assumed it was the Glow Plugs, these have now been changed and still encountering the problem. The Fuel Pump has also been changed. The Glow Plug DDE Light does come on briefly when attempting to start, but goes out. Should there be another Glow Plug light to show heating? I'm assuming pre heat is the issue? I'm taking this vehicle to Ukraine on Sunday so any help isolate the issue?
