I'm having some problems when the engine is cold... Lots of white smoke on start up, and if I don't let it warm up before driving it'll pour white smoke and die like its flooded. Once it warms up though it runs just fine... I've replaced the glow plugs, glow plug relay, and fuel filter, but nothing changed. What am I missing?!?

 

Check you pins on the valve cover gasket...I had a couple of smoked pins that caused my problem...check your UVCH as well.

Best test is to ohm out your GPs through the pig tails.
