Default cannot get 1st gen to run

Doing a cummins swap into my 95 dodge. Boaught the motor about 6 months ago. Has new inj pump when I picked it up the guy cranked it up for me and it purred like a kitten. Now that ive got it in my truck cannot get it to crank. I have a brand new elec lift pump. I bypassed manual lift pump removed plunger from stop solenoid. While cranking have inj cracked start getting fuel start closing them off and then just shuts down and have to start all over again. Plz help!

Yes. Cracked bleeder at filter housing till no air was present, cracked feed line at pump till no air was present, even cracked return line on pump.... no dice.

Check the manual shut off lever and keep bleeding. It can take a while to get all the air out.
