These VE's can be a bear to get all the air out of them sometimes.

I put a new lift pump on about a month ago, also have swapped injectors.
This weekend I swapped the IP and now it runs like it should.
It sounds so different, snappy and like a real diesel.
The old IP I could by hand, the new/used one pops when I turn it, you can tell it is building pressure.
Took me 3 tries to get the IP on right, kept shearing the woodruff key, so I pulled the whole front of the motor apart, bolted the IP down then put the gear on and key stayed where it was supposed to.
I'll tell ya when the timing is off it was making some horrendous injector knock because the timing was so far advanced.
