2001 Dodge Neon Getting Module to match my engine

I have a 2001 Dodge Neon That I had to replace blown engine. I replaced with a 2002 model. My Module is either blown or won't work with this engiine.I can't get info on the car that engine came from. I did get another module from a 2002 Neon and it powers up and turns engine,byt it still won't start.What can I do?
