I have a Porter Cable DA250C (15ga angle finishing nailer).
Worked fine yesterday until it just stopped. The gun does nothing at all when the trigger is depressed. It is not jammed. The piston is oiled and I can move it smoothly with my finger.
All the troubleshooting guides and other people posting online about nail guns always mention air leaking from somewhere. But, in my case, there is no air leaking at all. It just acts like it is not plugged in. But there is definitely air going in, it just does nothing when the trigger is pulled. There is no sound and nothing moves.
I took it apart, but nothing looks visibly damaged. Any idea which part may be faulty? Is there a test I can try to determine the problem?

It was the trigger valve. There was no visual damage or noticeable leaking, and I took it apart and everything seemed fine. But I ordered a new trigger valve and replaced it anyway, and it fixed the problem. Hopefully this helps someone else, since there was nothing noticeably wrong with the faulty part.
