A few questions:
1.What programming environment are you using?
2.Are you getting error messages in your debug console?

In FRC programs, the robot usually won't just automatically start the program unless you give it a specific command(In C++ it's START_ROBOT_CLASS) that points to what you want to start up.

It's also possible that your main thread is crashing very soon after it starts. If there are error messages coming out, these should be useful for debugging your code.
