need help

well i just put a water pump on my 92 talon tsi awd and i put it all together the right way even the timing belt and it wont start now so i dont know what to do?

go back and make sure your teeth on that belt are properly lined up. Just so you know next time you do this kind of job and have to take off the timing belt, you must index the timing belt. What that does, it keeps the alignment of the belt in place, unless you're replacing the belt altogether, that step is not necessary. Make sure also, that your belt tensioner is tight against the belt and also that you have the proper tension on that timing belt. Timing belts require a lot of tension than normal drive belts. A loose belt can cause a gear to skip a tooth and have you in the situation that you are in now.
