Are we actually sure the pump is delivering fuel to injectors (at any time in engine cycles)? Is it possible the brand new or rebuilt pump is defective?

Before mounting the repaired pump, I poured diesel into the intake while spinning the drive gear by hand, and diesel was pumped out of all 4 ports, and In my attempts to bleed out the lines at the injectors, I saw diesel pouring from all 4 injector lines when they were cracked open and the starter was running, so I would say that it appears that it is a timing issue.
But as far as I can tell, in this situation the pump could only be out of time if the timing gears have skipped, which is not all that implausible given how the pump broke.
