Both of my gas airsoft guns; vp70m and my sawed off shotgun no longer work, what can i do to fix them?

Question

I got both airsoft guns awhile back and both stopped working. When i use my can of green gas to fill them up they never seem to hold anything in. I will go to shoot after cocking both guns and receive no result. Is there somewhere i can get good instructions on how to fix this problem?
