smokes a lot at start up

I have an 01 and when I start it in the morning it smokes a lot even when its 50 degrees out. It also runs kinda rough. When it warms up its all good and runs fine. Would this be a possible injector going out.

Might be an injector or an injector cup. Check to see if you have fuel in your cooling system, if so it is an injector cup. I had a cracked cup in mine recently with the same symptoms.

Could also be a dirty FPR screen (dont think SD's have the screen, but they have something similar). My truck would do the same thing.. be a ***** to start, be smokey, run rough etc.

Cleaned the FPR screen and it starts without an issue, smoke free, no poor idle etc.

Yes, that is a sign of a bad injector cup. I do not think it is a computer diagnosed problem. I bought all new cups and did them all. The cups are not expensive, the repair labor or tool to do the job is. You can buy a tool online (I did and it worked great) and change the cups without pulling the heads or pull the heads and take them to a machine shop. Regardless, you will have a pretty big repair job on your hands.

I bought new ones, along with new glow plugs and glow plug harnesses. They are right there when you are working on the truck, so a little preventive maintenance doesn't hurt.
