electrical help required

OK, so when u turn the key on, if u don't see the throttle body power up u know it won't start? If it does power up, it will start? If so, I would key it on, if it doesn't power on, start wiggling the harness, especially the connectors and see if something makes the throttle body kick on. Also I would gently tap the computer with the back of a screwdriver or something. I've actually diagnosed a few modules like that.
