Good suggestion, Loren. Of course, you are assuming that it's been installed close to correct timing. If the pump is 180 degrees out, he may not see the fuel welling up in the delivery valve at the correct place of the crank rotation. Also, like we discussed earlier this year when I was mystified by my diesel with the bad delivery valve seals continuing to leak fuel, he may have fuel welling up before the start of delivery and should look for a stoppage of the welling up when the piston blocks the opening to the fuel reservoir. As one who has removed an OM617 injection pump to be bench tested and then replaced it, I know of the many questions one has before doing the process. Once you get it done, it's not so mysterious.
