Can vp44 injectors go bad? I sent a set in and the shop said they won’t build pressure to pop? What can be done to fix this?

Anything can go bad, except for a dog's love for a man.

If they won't "build pressure to pop", I'd imagine that means that they're leaking too much internally. You probably have lots more fuel going out the bypass than usual.

The fix would be to replace the injectors with new(er) ones that have tighter internal tolerances.

The fix would be to call Weston Shupe at Infinite Performance and have him build you new ones.
