I just changed the timing belt on my 05 chevy aveo whats wrong now?

my wife was driving the car and the belt broke, she was only going like 25 mph and she coasted to a parking lot. I aligned the marks on cam shaft sprocket and the intake/exhaust sprockets. If you try to start it it fires the first time and not again unless you let it sit for a few minutes then it fires again. Do I need to take my timing belt back off and spin the camshaft sprocket one more revolution like VW's? If I recall TDC can either be cylinder 1 or cylinder 3 please if you have any info besides bent valves it would help tremendously thanks.
