Ok not sure if this is a good place to post this but, when i hook up my scan tool and set it up like it's supposed to, it says vehicle not responding. Anybody else have this problem? Could it be that the ecm is from another year car? Thanks in advance!

I found out what the problem was. The scan tool wasn't making a good connection at the ALDL. I had to mess with the wires on the back of it and it started working. Thanks for the help though.
