Ok so here we go, it's been a while and k have been doing things a little at a time. I have brand new injectors, brand new glow plugs and a brand new injection pump that I put in just last night and the injectors a few weeks ago. My question is why now does this thing decide it's going to blow nothing but white/grey smoke when its idling to warm up but once it is at running temp it doesn't smoke any longer and runs fine?

did you replace the fuel return lines? maybe a clogged or leaking return.

There is an oroficed fitting right where the return line goes back to the tank. Check that it isn't plugged up. Check your tank switch valve to make sure it switches all the way on both sides, and isn't restricted on the return side especially. White smoke generally means unburned fuel. Check the compression. That could be an indication of worn compression rings. Retarded timing can also cause that. In fact I would probably check the timing first, since you just replaced the IP.

I should also add that before I changed out the IP that the truck ran great except not wanting to start after the engine was warm

Where did you get all these "new" parts?

Did you time the new pump with an instrument or by ear?

Also, when you changed the injector pump did you remove the gear cover?

Yes I pulled the gear because I didn't have the 9/16 specialty tool or the ability to make it at the time. I did how ever mark the gear and the inspection window so I could line them up when I reinstalled it.

Hopefully you got it put back on the same tooth.

Since I don't believe there are any more "new" injectors or pumps left, I don't know if a rebuilt set from O'Reilly's would be matched and calibrated properly.

According to what I heard from my mechanic friend there should be a mark on the pump and on the back of the cam gear housing

Chuck will tell you how, but the bigger point is you need to pull the injectors and have them pop tested. Having the pump gone through by a good diesel pump rebuilder would be nice as well.

If you removed the gear that drives the pump from the engine, then the best way to replace it in the proper timing is to remove the entire timing cover. and line the marks up as per the manual. There might be a way you can cheat, but most of those ways usually only work if you get lucky. By the way a torch can make any specialty wrench you want.

When I get home I will post the link on how to time the gear without taking the front cover off.

As far as timing the pump, I will explain it when I can type on a keyboard not tap on my dumb phone.
