The first thing we need to do is check the cigarette fuse which powers the ALDL connector. Here is a guide that will help and the fuse location as well, also I have included the wiring diagrams so you can see how the system works.

If the fuse is okay, you might have a PCM that is out, let me know what you find. Check out the images (below).
