Is it possible he has a visual challenge? This sometimes seems to be the issue with good readers who are relucant to read themselves, but prefer to be read to.
I guess my point about "Boys like..." is that while I certainly think it's fine to offer nonfiction and Capt Underpants, etc, I wouldn't get into the mindset that it's pointless to offer other diverse chapter fiction to boys. It may just take a while to hit on the right thing, or sometimes it's a maturity issues. DD has a friend who was not interested in reading really at all till about age 8, but now he's a major fiction buff. They kept reading aloud and kept trying different things, and actually it was Harry Potter that clicked.
