This spring in Zone 5 my wisteria is looking totally bare, no leaves or blooms. The wisteria is at least 18 years old and has been growing on an arbor. Early last fall I pruned the vine, but this winter I did not. Yesterday, I found two green buds that look to be growing. How should I prune the wisteria this year if it is still looking very bare, no growth showing? I want to know if it is dead or dormant.

This spring has been a rather cold one for most of the US. And that has kept some plants dormant longer than they usually are. As long as the branches are pliable and you are seeing signs of green growth, the plant is still alive. It is just taking a little longer to wake up, is all.
You can go ahead and prune it now or you can wait until you see more growth. Wisteria will tolerate pruning at almost any stage.
