I am trying to fly my drone and when I put the sticks in position to start motors I get nothing .    Then in the DJI GO app it says “. Warning IMU initializing don’t move drone “. How do I fix this ?   

Hey Andyibe, just to verify, has the drone been involved in the crash or hard landing before? What's the current aircraft, controller, and APP version? Does the gimbal do self-inspection once powered on? We will appreciate if you can upload a short video for better assistance. Thank you in advance!
