Hmm, not exactly true......if you let air in at the injectors then tighten them up there's air bubbles stuck in there...priming the system chucks diesel in, but its not gonna let the bubbles out is it?
Had the same issue on several CR small vans at Ford (Transit Connects iirc), albeit after a fuel filter change and that was the techs solution....once its started keep it running to clear the air out....
