I took the nail gun apart to diagnose the problem and identify the faulty part. Then I visited your website and was able to easily find the exploded diagram/schematic for my tool. I ordered the specific parts needed by item number, recieved everything a few days later, and had my nailgun back together in about 10 minutes. Field tested it the next day.
This is not the first time I have orderd parts successfully from your website and being a professional tradesman, it certainly will not be the last. You offer a great service.

I found that the air valve was sticking due to hardened o-rings. I really just needed to two smallest ones on the trigger stem but I bought all of the seals for the valve since I was there. Porter Cable model DA250A.

Tools Used
Screwdriver, Pliers, Wrench Set, Hammer , pin driver
Everyone said top bumper causes the problem. The bumper was shot so I replaced it. Still did the same thing. Messing with it I found that if I pulled on the trigger pin just a little bit it would let go and retract the driver. I pulled the trigger assembly out and started messing around with it. No luck. However I now noticed a slight air leak at the trigger. I purchased all new O rings and trigger pin and spring. Installed and WahLah. it works. Thanks for your help with parts. Have referred U to friends.

Nailer won't fire, only leaked air while the trigger was depressed in the trigger area

Disassembled the trigger and then removed the trigger valve from the body of the gun using a socket. I replaced all of the O-rings in the trigger area and lubricated them with the oil that comes with the gun. I then reassembled the valve and screwed it back into the gun body. I reassembled the trigger making sure that the safety worked as it is designed to. The gun worked properly after the repair and continues to at this point. I am satisfied that the O-rings were the cause of the problem.
