HPFP timing mark absolutely matters. The idea is to pump fuel into the common rail while it is simultaneously being injected. You want to keep the pressure in the rail relatively smooth and constant based on demand. If you have it slightly off you would have pressure drops in the rail as the pump is out of sync.
