I have been searching and still can't figure it out. I have changed out the glow plug relay with the stancor and just tested all my glowplugs. two I found were bad and changed them out. Still to find it smoking on startup when cold. Any Ideas????

ok, I went out and checked the new relay and am not getting any voltage on the yellow, and brown side with key on. I will double check it in the morn with it sitting and cooling over night. I have been looking around on here and see that I can jumper it to check relay but with it being brand new stancor and still not getting voltage on that post I guess I am looking at a pcm prob. Any ideas of where to go from there if it is?

Went ahead and changed the other 6 glow plugs today, so all 8 are brand new and working. Also the gpr is brand new and works. Still having the same white smoke issue when the truck has sat for a few hours. Anyone have any ideas, it goes away after you get going down the road, just makes my truck look like a piece of junk on startup.
