Pound cake goes flat

Q: My whole family has tried to duplicate my grandma's pound cake recipe without any success. It tastes the same but doesn't rise and if becomes a really heavy dense cake. Any idea why the cake won't rise? I want to be able to figure this out and make it for her. She just broke her hip and she is 93 so who knows how much longer we have.
