In addition to what Dave said, if he still isn't eating we need to know more detail about the situation before we can give any insight.
How old is the snake?
What kind of setup is he in? (including substrate, etc.)
What are his temps/humidity?
What have you tried?
Have you allowed him to settle in before trying?
Until he begins feeding for you he shouldn't be handled unless it is completely necessary. Good luck and congrats on the new snakie
