This thing has less than 20 hours and looks brand new (passed
warranty). I contacted Stanley/Bostitch and replaced just about every
seal this thing has, including the trigger valve. Using 110psi, I
press the trigger and air comes out of the trigger but the gun does
not fire (cycle). I'm not about to send this to be repaired since I've
seen these refurbished for around $50. Any ideas? When I put it away
last July, it worked.

Have you put oil in the gun? Several drops *down the hose connector?

Just dropping a little oil in the air inlet may not be nough for a gun
that has set up for a while. The gun may not be working well enough
for the oil to get where it needs to be. Take the gun apart and
reassemble replacing parts as needed. Apply oil while its apart.

True. The OP replaced some parts, likely to have lube instructions for
assembly. Some parts need lube during assembly. I don't have
problems with pneumatic tools. Trick is keeping compressor / line
moisture out of the tool. My 30+ year old half inch impact wrench has
leaked oil in the bottom drawer of the tool box. No problem. I wipe
the drawer clean.

Hope the OP tells us what he found to be the problem.
