White smoke indicates that water and antifreeze are getting into the combustion chambers, probably via a bad head gasket. Black smoke is fuel. Blue smoke is oil.

Ok, question, was this a KOEO or a KOER code? What scanner or code thingamagig got you this code? Can you post PID data?

My big problem here is "blowing white smoke out of tail pipe" then you say no start.

If said engine blows white smoke, said engine fires. Hence spark, fuel, combustion, etc.

A leak down test would be cool. Also a block tester to verify if combustion gasses are indeed infiltrated in the coolant. You may have a bad head gasket. Cheap to check that out. Logic is the way to go.

If you see white smoke, there is a definite coolant loss in the combustion chamber.

You wanna here something funny, guys? A guy walked I've from across the alley, sprayed a bit of something onto the intake filter, and the truck started! It ran rough at first, like it was missing. Started it later and it ran better. So, I'm confused, but happy.

Maybe this guy just sprayed some brake cleaner or carb/choke cleaner. Probably got washed cylinders in coolant and the cleaner was the peak compression accelerant needed for lack of a better explanation. If you could post compression readings, that would be of an advantage.

This is as Jack says, this seems like this is going to be a ongoing problem/situation. My reading of this thread is maybe a few cylinders were washed in coolant and when the guy sprayed some stuff, it ran. Ok.

My question is, did he spray Ether??, cuz a diesel should not be able to run with something like carb or brake cleaner.
