Time to replace a few orings in the trigger valve. There are at least three orings made of vinyl that fail, two on the trigger pin and one on the plunger.

Have you been lubricating it regularly with nail gun oil. We use framing nailers every day at the commercial tree farm I work at and one of the operating instruction is to put 6 to 8 drops of oil in the air hose connection on the nailer before every use. I suspect the O ring on the piston is worn out/
Hope this helps Good luck Loringh PS Please leave a rating if appropriate Thks

Check whether the trigger is working properly, and whether the air valve is not leaking.
SOURCE: Dewalt 51488. Air leaks around trigger and won't fire nail.
Go to Dewaltservicenet.com and download a breakdown of the tool before starting. I would recoment changing all the O rings and make sure that you get a good grease to lube them first. Its not that hard.

First - the air pressure has to be high enough - check the regulator on the tank to make sure it is delivering in excess of 60-70 psi (which I am sure you have already done).
If you have dry fired these guns (i.e. shot them off with no nails in them while you were lubricating them maybe) the mechanism inside could be damaged. I had that happen to one of my nailers (same brand). That was when I learned not to dry fire them...
Since both of them are not working though I would be more inclined to look at the air supply first.
