Hi and thanks for using 2CarPros.com.
This is a tough one. Does anything electrical work? Have you checked main fuses under the hood in the power distribution box? Keep in mind, this could be as simple as a dirty connection at the battery or a weak ground. Have you checked to make sure the battery terminals are clean and tight as well as the grounds to the engine and body from the
battery?
Take a look through this link:

Are you sure the battery is good?
Let me know.
