Please note that the engine has'nt been messed with yet. When I disconnect the injector lines, fuel is present in all the injects.

If you have their is no oil up their that is diesel fuel most likely. If the injectos is covered in fuel the drip lines are probably leaking. The diesel will pool down around the base of the injector and look like an oil leak.
Now if you pulled the injectors and found the prechamber was wet it means you have a leaking injector. You should get all 5 checked at a diesel shop, the one I go to only charges $10 each to check them.
