By doing a pressure and spray pattern check, this can either be costly or messy, depending on if you do it yourself or have them tested at a shop. Most times it is just a safe bet to replace all of the injectors on diesels, but I have to warn you if the diesel you are speaking of has mechanical injectors (no wires running to each injector) you may have a problem with the injection pump($$$$$), most common problems are the pump is out of time, or somewhere a seal is failing or has failed, or it needs a fuel delivery system cleaning and filter replacement. I have never actually heard of mechanical diesel injectors being replaced due to wear, although I am sure that has happened once or twice before.

Gravity. Or your fuel pump is bad. There should be enough pressure from your fuel pump to push the fuel to the injectors. A clogged filter could do it also. I would change the filter first.
