Benjamin Marauder.22 rifle problem?

I took my rifle out of storage after about 4 years and it still had a little air pressure showing. At that I fired it empty and it worked. Fill to about 2700 psi and now when I try and fire all I hear is a twangy sound and no output? Any suggestions? Here’s a photo.
