Problem with stock air shocks

I'm wondering if anyone else here has come across this. Basically I can't get air into the shocks. Try to pump a bit in with a couple different hand pumps and it just doesn't get air in there and there is plenty of back pressure when pulling the pump off. Maybe my method is flawed but I'm assuming there is no air in there because when I try to let air out I get nothing. Oh yeah, and the wife gives PLENTY of input on how she feel every bump back there. I have pulled the seat and traced the lines and there are no kinks in them. Everything appears to be seated correctly. Short of taking the lines apart and trying to pump air, I'm out of ideas. It's a 2012 RGU and I'm trying to make the dealer my last resort but it may come to that, just trying to save a bit of hassle and I really don't mind wrenching. The only way to learn is to do. But it may end up at the dealer for warranty work if no one here has ideas.

Could the threads on the valve be cross-threaded so that the pump is not going on correctly?

Are you using one of the "clip on" type hand pumps or a screw on. I tried to fill mine with a bicycle pump that clips on and got the same results, backpressure but no flow. I bought the little screw on pump made by Harley specifically for the job and it fills fine. Expensive little pump (like $40) but it really is pretty nice for the job. It has a gauge on it and it does not let air escape when you unscrew it.

I have the little Harley pump. Same result.

Threads on the pump and the valve are perfect and I'm sure I'm not cross threading.

And I've tried a clip on pump as well. All with the same results.

Kinda like the lines are plugged or something. Don't know if that's possible but that's what it seems like. Unlikely but I guess we never know.

Sounds like the valve in the bikes connecter isn't getting compressed for some reason, so basically you're only filling the pump hose. Most often this is caused by something screwed up in the pump hose connector, little nib in the center is missing or messed up. It's possible the valve in the connector n the bikee is screwed up, but not likely.
Take the pump back to the dealer and see if you can compare it closely to another one.

Similar to tdkkart, check to see if the valve on the receiving end of the shocks depresses. Might be stuck, or somehow the pump is not fitting tight enough to depress it.

Valve core appears to be ok but may be the next/ easiest route to go. I do have the Harley pump and use it or at least attempt to use it. Just tried other pumps to see if they did anything. Well maybe I'll try replacing the valve core tomorrow. If not, off to the dealer. Thanks. Still open to more ideas also though.
