I just put a new injector pump and piston pump on. It is a little hard to start when it sits over night and it blows a lot of white smoke. It still blows white smoke when it is all the way warm. I can't find any fuel leaks. Is it possible that my timing is to advanced? The marks line up, but is it possible that my gear skipped a tooth or two? It sounds a little clanky when its in gear, but not when it is in park or nuetral. Any suggestions?

Based on your description (white smoke and clanky), the timing may be too far advanced for what ever reason.

Does it sound like a powerstroke? Timing may be too advanced. I imagine it would be easy to skip a tooth if you're not careful.

So if I retard the line on the pump if I skipped a tooth would it be ok, or do I need to go back in and line the teeth up?

I think you have an air leak.

White smoke at idle = retarded timing.

So I need to advance the timing? It is a constant white haze. The truck is all stock right now so I shouldn't be over fueling. I don't think it is a head gasket of anything like that cause I'm not mixing oil and coolant and I'm not using any coolant. I think that it is a timing issue, but does that explain the hard start? It feels way under powered too. Maybe cause its stock? Does 14 pounds of boost sound right for stock?

Because of the hard starting issue, I think the whole problem may be an air leak in the primary fuel system. Check it thoroughly, even with retarded timing the truck should start easily.

Ok thanks. What is a good way to check for places air could be leaking into? I'm not leaking fuel anywhere. I know air could still be getting in somewhere though. I retarded the pump about a 16th and it seems to be less noisy and run a little better to me, How would it run if it did skip a tooth on the gear?

Pressurize the fuel tank to a couple psi, that will push fuel out of any air leaks.
