How is it not communicating? No codes, or no data? I've found sometimes it works to tell the scanner it's a year older or newer.

Is the check engine light on? Try manually flashing the codes and see if that works.

An OBD II Scanner will not work on a 1993 unless it has a plug for both systems. I do not know if the Snap-On Scanner is for both systems or not. A 1993 is OBD I.

Use the self test using a paper clip, go to this URL to find out how:
