hmm for some reason.. this is not the kind of connector i have on this car.. the on i have is like OOOOOOO 6 spaces all occupied with a wire behind it. I tried the right first two cause i thought that would be a and b.. but its not working.. hmmm

I found it.. it was wayyyyy in the back under some wires.. so im not sure what the 6 slotter is doing there.. though its a 16 slot obd 2 connection.. not a obd 1 connection.. its a 93.. so im not sure if its just a obd 1 with a an obd 2 connection or not.. though.. :banghead:

Ouch.... OBD 1.5 is really hard to track down... I'd say that on a 93 you have an OBD1 system with an OBD II connector, but I'm not sure--Its a bit too new for my blood. Have you tried to figure out if you can jump any of the pins? Hmmm...tricky.

im familiar with OBD I systems having the OBD II style connector, heres i'll post what i know...

i found this a while ago, glad i kept it.... http://xgamesj6.tripod.com/gmcodes.htm check it out, has info and all the codes

Tried that on transitional year GM vehicles, never got it to work, you will need a proper full function scanner.

93 is kinda early for it but 94-95 have a change over years that require a engine capable scanner with a special adapter to get codes.
Does yours have A and B wires on diagnostic plug?
Does check engine light come on key on engine off?
Here is a link that tells about the 94-95 years.

well my mom said the car was a 93.. cause that what the title says.. the vin number pulls up a 95.. so im going by the vin number from now on.. so it must be the change over... figures :iceslolan

Somebody at the DMV screwed up the title the last time it was issued. You may have to find a mechanic with the proper scanner as I'm not sure that autozone has the right one. It would still be worth a shot to try them before paying someone else.

howdy to all of you fellas,
I stumbled on this excellent website. Am experiencing a dark night of the heart and soul and I ended up right here. Look forward to reading all the info and also threads.

If I was you I would get a scanner that is for obd1 and obd2 it was the best 250$ I ever spent!!!!! auto bone has one for both for around 500$ I got mine at Oriellys for about 250$ and it came with everything I needed to link to my laptop and get online for ASE cert. tech support
