Use a meter or test light to be sure you have battery voltage on pin 16 and ground at pins 4 and 5. If no power check the DLC fuse in the under hood fuse block. If you have power and ground then try a different scan tool or try the one you have on a different vehicle to verify it works. What is the issue you are trying to scan for?
