Wont idle, new parts, why?

Just a swag but going on the idea of an air leak check the connections at the electric pump, then run the electric pump and see what comes out at the injector pump input. It's likely gonna be air-entrained for a while then clear up (the electric pump will push through the lift pump check valves). Then just wet your injectors and drive home. I have an electric pusher pump and have found it handy for this sort of job as well as filling new fuel filters, and in my case pumping out a bunch of water contaminated fuel. The down side is that air leak possibility since it's on the "pull" side of the lift pump

Ok im lost
So far I have run a hose from lift pump to a can of diesel and it still does it, so its after the pump....could it be my injection pump?
once agian I can bleed the injectors of air and it will crank and idle for about 20 seconds and if I dont give it the gas it will cut off but I can keep it going if im giving it fuel but its still rough......
and I cannot seem to get an o-ring to fit in the fitting on the pump. I slide it on the shaft and then try to put the line on and it wont "buckle" I guess.

When it is running is it smooth? How about smoke?
Wanna wouldn't the ip pull enough fuel at an idle for him to plumb everything out except the ip? Like run a line from the pump into a can of fuel.
That would elimanate(spelling?) from the lp to the ip.

Well after I get done bleeding some air it will crank and idle descently for about 15-20 seconds then will idle down and cut off.....but if I hold the throttle and idle it higher it will stay running but very very rough until it gets to higher rpms

I would try and elimanate all possibiltys before saying the IP. Wanna may chime back in here and say if the IP would suck enough fuel at idle with out anything supplying it. Before all of this happend were you noticing anything else with the truck, low power, smoke, hard start?

No it ran fine.......
Like I said I bougt the truck with electric pump on it but not hooked up.........well I hooked it up and ran it but then when it wasnt on it would miss fall on its face till I would turn the electric pump back on. I just got done putting my 5 speed in and we took it down the rd, it sputtered and cut off, we pulled off and hooked up the electric pump, went on down the rd and it sputterd and cut off agian but this time it wouldnt crank back.....now I have to bleed the injectors to get it to run at all

This is really sounding like a bad VE to me.
