Volvo MD7A Not Starting

I had my injectors rebuilt on my md7a. Put them back in and it ran good but the idle speed was little high. Adjusted the idle down to about 800 and it idled fine. Turned it off and tried to crank again then it sputtered a few seconds and it will not start now. Have replace all filters and bled it forever. Have tried startng with vaious ammounts of throttle and it acts like it wants to hit but end up just getting white smoke. Took the injetcors out and had them tested and they are fine. Thinking it may be the high pressure pump at this point. There are no bleed screws on whatever high pressure pump this is. Maybe the white smoke means it is getting fuel but not at proper time or ammount. Anyone have any ideas or does it sound like it is high pressure pump rebuild time?
