There is probably a breaker box in the bedroom closet behind a panel. Look elsewhere if not there and check the breakers when you find it. You may have a short circuit somewhere and the breaker opened. Or maybe even a failed breaker. Check for voltage at the breaker itself. Don't assume the breaker is getting power.

This video may help. First you must see if it is a fuel problem or an electrical problem. Spray a little starter fluid into the throttle body and see if it starts. If it does, check fuel system pressure. If no pressure check fuel pump for operation. If it still does not start then there is an electrical problem which could be anything from a module to a fuse.
I have a question for you in order to be able to better help. Is there what appears to be a plumbing vent cap in that area? If so that is most certainly where your satellite prep cables are located. If not can I get a picture of the roof?
