Tech Adept
A few ideas:
1. Make sure you haven't locked the pinion into the spur. If they are meshed too tight, the motor will not turn and you will fry it.
2. Check the connection of speed control to the receiver. When you pull the trigger on your transmitter, does the light on the speed control change (assuming you have one)? If not, you may have a bad connection.
3. Make sure your brushes are connected on the wire end and making contact with the comm on the brush end.
Hope this helps.

My bet is that you have a hung brush. Can you slide a brush in and out of the hood easily, without binding? Someone has already asked you, and you haven't responded. So?
Check for a hung brush!

1. Make sure the springs are engaged properly on the post and putting force on the brushes
2. Pull the brush shunt lightly with the spring engaged and see if it slides in and out smoothly, then let it lay back onto the comm
Try the motor now, if it doesnt work continue
3. Take off the spings and slide the brushes out of the hoods, make sure they are not cracked
4. Make sure the brushes slide smoothly in and out of the brushhood if not clean or re-side the brush hoods
Re-install brushes and springs, try the motor, if it doesnt work, take it to a hobby shop and have the tech guy there look at it...

Have you ever opened a motor before? I would guess "no" since your spelling leads me to believe you're a 2nd grader. 
(Sorry, I _HAD_ to give you a hard time...) Unscrew the screws in the top of the motor to release the endbell from the can. Release the springs from the clips on top of the hoods, and remove the springs. Remove the brushes from the brush hoods. Remove the endbell from the can. Pull the armature out of the can.
Do you have a loose magnet (not attached to the inside of the can anymore)? If so, you can reattach it with some JB Weld. Has your motor thrown a winding? Meaning the wire which is usually wrapped around each of the 3 armature stacks has come loose/broken loose/had a solder connection melt and release the wire.
If you have a DC multimeter of some sort, you can do a simple continuity test on the armature. Turn the selector knob on the multimeter to its continuity setting - ie. "lets out a 'beep' when you touch the positive and negative probes together". Touch a commutator segment, then touch an adjacent one. You should get a "beep". Try all three segments to make sure you're getting a connection (a "beep").
