Did you try the scanner in another car to see if it works?

You should check the grounds (2) of the connector as well, here is a guide to help and the OBD2 port wiring diagrams so you can see how it works and which wires to test. Test the black and blk/wht wires for ground. Check out the images (below). Let us know how it goes.
