Did he hook up the go pedal cable at the IP/HP pump. If it runs then just reach in on the pax side(USA) of the IP and push the throttle lever to see if the RPMs will rise.

What year is this truck? The terminology makes it sound like it might be a 7.3L Powerstroke (High pressure oil pump Vs injection pump)
If its an IDI, beyond the throttle cable and lever it would have to be something internal to the pump. Check the lever as PLC suggested, if it doesnt respond I'd think the replacement pump must be no good.
