I replaced all 8 injectors all new glow plugs new turbo but I still have a white smoke when I start it thanks

White smoke is a sign of water vapor or fuel that has been atomized, but not burned. Water vapor may be present in the fuel, or water may be leaking into the cylinders from the cooling system. Also, air in the fuel can cause white smoke. White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust, during cold weather, until the engine warms up. Bad glow plugs (burned out, coated with carbon, or not receiving proper start-up voltage) or a faulty glow plug control module can cause white smoke on engine start up. Low engine cranking speed may also produce white smoke. If white smoke is visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing, or worn injection pump. Low compression can also be a source of white smoke.

Thanks I don't think it would be a injector its not knocking like when the old ones were bad how can I tell if there's air in the fuel would a scanner tell me anything thanks

Yes, some scanners can provide that information.
