when I start my truck first start of the day. It blow white smoke and has a miss untill it warmes up abit. drive down the road 1/4 mile. Its still summer here so I dont let the glow plugs burn all that long. But I wouldnt think it should smoke as much as it does.
Injecters need to be reworked?

Its been doing this for awhile just figgured I would ask away. Kinda bored

Could be a bad glow plug or two or a bad injector. With it still being fairly warm out I'd lean toward and injector. Do a cylender contribution test on it and see what it says.

That is a glow plug issue and the white smoke is unburned fuel. You either need to install new plugs, or new GPR, or new batteries, or new cables.
When my 96 did this, I installed new glow plugs and that did not fix it. I installed new batteries and that was not it. I was informed by someone it might be the cables. Cables looked good but that was the problem. It lights right up now even when it was below 0 this last winter.

I too have a rough runner first 5 or 10 minutes with some white smoke on startup....Glow plugs and relay are new. It started when I swapped injectors. I think it's an injector problem.

Mine started that after adding an intake and losing a cat. White smoke at start up is cold combustion temps. Brand new Cat engines blow smoke too

Mine quit after the IPR crapped out & replaced it with new.....

Most of the time you could still see the truck...(its white).......

White smoke is kind of the classic g/p system indication. That is also easier to check out than injector issues, so it makes sense to start there... ohm them out and confirm the relay is giving them power.

If you eliminate the g/p system as the problem, the first injector test would be measuring the clearance under the armature plate (which would reveal worn poppets). The classic symptom for worn poppets is the miss on cold start that goes away like someone "flipped a switch" and it then runs perfect. Also seems to show worse after extended cold soak when the oil is nice and thick.

Oh, does the motor run great when it's warm?

Do you just have stock ADs? Should try going back to some singles that flow 160cc or so of fuel. I think you will like them a lot better.

In good time I will....

I'd say Glow Plugs or injectors.
