Rosco was like that when we brought him home. A couple of suggestions: give treats for going in the crate periodically. Also, I used to leave an old pair of jeans I had worn for a few days in the crate with him, I don't know if having my scent was comforting or not but it quieted him down sometimes. Another idea is to get a little stuffed animal puppy for them to sleep with in the crate.
