Car starts but won't move in any gear .

If the engine starts and rpm changes when you rev the engine but the car does not move when forward or reverse is selected something in the drive train is broken most likely a transmission failure.

Have same problem with mine. What I have to do is pump the breaks then try it again.

You're transmission may be bad you may also try the shifter cable as well. I was having similar issues with mine. I hope this was helpful and you have you're car up and running soon
