OBD-1 codes and OBD-2 codes

[GT1993]

ok i have a 93 gt and recentlly it just died on me while driving. everyting points to a bad distributor but when i replaced it nothing. now im trying to pull some codes but i cant get the damn cel light to come on. i did it before and it worked fine but now when i connect the ten and grn the cel light doesnt come on at all. as a matter of fact it never comes on.
Doesnt it come on when you first turn the key to ( this is without the clip connecting the ten and grn) ?

No, you have to jumper 10 and ground, then turn the key. Don't start it, just go to the "on" or "acc" position. Should work. As for the problem, I'm not technical enough to advise, but if nothing works, then it does sound like it's electrical.

Thanks

Are you shure that it had started looping and it wasn't a separate code? Mine never put any sort of "prefix" in. My codes just looped the same every time.

I know i have to connect the ten and ground to check for codes but i was just wondering is the cel comes on when you regualrry first try and start the car.

My bad. Yeah, I think it does. I'll double check.

CEL light comes on in the "on" ignition position, not "acc." It stays on in that position. If you crank it, the light is still on for a minute from passing by the "on" position, but then goes away. Hope that helps. I have an MX6, don't know if Probes are different in any way. Wouldn't think so.

When pulling codes, it will not light up, if you do not have a small enough paper clip to fit all the way down into each connector.(rember only use 1 paper clip and DONT cut it in 2 pieces)

I suggest just to do the fix for the first code(only becuase its easy to see where the 2nd starts, but after that its difficult) then after you fix the 1st code, reset the computer, and then see if you pull any more codes, and so on.... if you need more help PM me.

ight... half my stuff is fixed.. now my car is running some crazy codes...
i reset the coputer. disconnected the negative and pressed on the break for a little more then 5 seconds. the ran the codes again..
now it starts off with 4 long , and after that i get 6 short.
now i remind you i have an OBD1. what the **** kinda code is that?!?!? im not sure if there seprate codes or togeter. but i redid it 3 times to make sure i knew how to count. They look seperate.
anyone know what codes these might be??

[noclss2000]

hmmm, no idea
I looked through to see if there was anything close to it like 40 and 6 or 46 or possibly 460 or 406 and nothing. Just kick it, that always seems to help
