my timing belt is not letting my car start

 

I just replace the timing belt with the new one but now the car won't start won't even crank

 

Well, the timing belt doesn't turn the motor itself. That's done by the starter and electrical system of the vehicle. An incorrectly timed motor should still turn over unless there is internal damage to the engine - even then you would still probably hear the starter making noise.

Sounds you you need to troubleshoot that first. Without any information about your vehicle or engine, this is the best anyone will be able to do with help.
