You have an OBD I car with an OBD II style plug. Most autozones only have equipment to test OBD II, a few can test OBD I. If they plug the II scanner into your car, they will get errors. You can go to a mechanic or to the dealer to scan codes.

If you can get your hands on an OBD1 scanner all you have to do is hook some wires up. There's nothing different about the system except for the connector. If you can hook up the wires to where they're supposed to go the scanner will work.

You're looking for this:
12-pin style:
F E D C B A
G H J K L M
A = Ground
B = Mode Select
M = Serial Data
OBDII style:
01 02 03 04 05 06 07 08
09 10 11 12 13 14 15 16
05 = Ground
06 = Mode Select
09 = Serial Data
If you run your ground, mode select, and serial data from the obd2 connector you have in your car to the terminals on the scanner, you should be able to pull up any codes on your car. It's probably not the easiest thing in the world, but the alternative is more money. Some wires and some little jaw clamps would probably be enough to pull it off.

If you really wanted to you could go to the junkyard and yank an obd1 out of something, then do the wiring from behind so it's not so difficult in hooking it up. Juggling three wires between two connectors will be difficult at best.
There's nothing electrically different about interfacing with the pcm, it's just that GM decided to be stupid and change the connector the last year obd1 was out on these cars.
No worry to me, though, I already had a laptop, so scanning and tuning capability only took 100 bucks out of my wallet. Especially since most of the tuners claim they can get almost 15rwhp on a stock engine... maybe with my intake, exhaust, etc. I can get a few more hp out of it.
Cheap and easy. Wow, you don't see those two together very often...
