Does the light blink once, when you turn the vehicle on?
Nitro or electric...

Are you plugging the bind plug into the bind port. For electric, is the speed control on before or after you install the plug? You should turn it on after. And is it installed in the throttle or steering port instead of the telemetry ports?
Unplug everything except your power source, either ESC or RX pack, and bind plug and try that.

Are you putting the receiver in bind before the transmitter? Can you bind any other model RX to your transmitter?

Need some more information... By the way you have asked, the easy answer is" cuz you are doing it wrong." And that doesn't help you one bit.
