When you plug into the DLC, does the scan tool power up and indicate it is connected?
If you take a look at the attached pic, it shows the data link connector (DLC). I need you to first confirm there is power to pin 16. You should have 12v there. If you do, then I need you to check pins 4 and 5 for continuity to ground.
Here is a link that you may find helpful when doing this:
Note: If there is no power, confirm the fuse for the dome light (highlighted) is good and has power to and from it. Here is a link to help with that:
Let me know what you find.
