Trim pump help

Mercruiser 5.7 with alpha one out drive. Pulled the trim pump lines and I will get a steady stram when down button is pushed. I get no fluid(but pump runs) when I push the up button. Is the pump bad? It worked great until yesterday. Thanks.
 
Is the pump bad?
Tap on the valve body w/the handle of a screwdriver...valve may be stuck. How old is the assy? I threw a working assy in the recycle bin last spring...was sitting around taking up space. Motor needed a brush assy. Never got around to it.
