Welcome to Just Answer Chrysler my name is Mark.
Here are the installation instructions. Compare these to what you have in your manual and see where the difference is. It does sound like the timing is not set correctly. The last step is VERY important to do before you put this back together.
Ok one thing that I have seen more than once is the dowel pins for the cam shaft sprockets can break. So, although the actual sprocket marks may still line up, the shaft itself may not be in the correct position.
You may want to look into that possibility.
