Make sure you have good (fresh) diesel. Have your throttle lever full on. It needs to push fuel in to get air out. Loosen the nuts at the injectors (so the air can get out). Turn the engine over for 15-20 seconds, then wait for a bit so you don't overheat your starter. After several cycles of this you should see no air bubbles as the fuel comes out. Then tighten the nuts (19 mm, I think). She should fire off. May run rough of a bit, but will bet better quickly.
Welcome, and stick around and post some pictures and let us know it goes if you have additional problems/questions.
You did no damage.
