smoking at cold start
 

have gotten two opinions on why my dodge 3500 smokes at start. one says fuel injectors and one says its the pump. who to believe?

welcome to diesel bombers and does the smoke clear up when it warms up and how many miles on your truck Diesel Bombers Introduction - Diesel Bombers need to go here and introduce yourself and put the things youve done to your rig in your signature :yeah:

only when its cold. and its white smoke. once it warms up it runs fine. has 188,000

it's completely normal and even says in the owners manual that it will do that. It's just raw fuel not being burnt because the cylinder is so cold. White smoke can mean a bad injector or a few other things but, the fact you say the truck runs fine once warm tells me what I said above.
