Bad Injector??
So my truck smokes like a frieght train when I start it and its not at operating temp. The smoke smells like raw diesel and visually goes away when the engine gets up to temperature, but still smells a little like raw fuel. So reading on the forums, I have started trubleshooting this problem. I have a new GPR, all new Glow Plugs, and good fuel pressure.
I traced the suspect injector by unpluging the VCH's one by one until the smoke stopped. After that I pulled the VC and unplugged the two injectors on that harness and found that one didnt make any change in the sound of the engine but did stop the smoke issue.
Since I can assume this is the injector haveing issues by the fact that I can unplug it and remedy the problem, the wire harness should be good I would think.... Or am I missing something?
Time for stage ones?

Swap the pass. and driver side UVCH and see if the problem follows the wiring if not the swap the injector you think is giving you problems with the one next to it to see if the problem follows the injector

What if any mods are recommended if I go to stage 1's? Pillar gauges are soon to come.

So I could do the budget stage 1's with Jim? Is it recomended to change cups while doing the injectors or just o-rings?

Yep they'll just run like stock stick till you get a chip.
I wouldn't touch the cups unless you see a crack in one after you get the injectors out
