Strange problem

[ATrom]

Ok so I am having misfires..I tryed to connect it to a scanner to find out which cylinder its coming from but however, every scanner I have tryed says it cannot connect with my car??? I am not sure on where to start to figure this out.. I wonder if it's just a fuse blown on my computer connector or something? Or if I just need a new scanner plug-in on my car?
Please help

I would check for blown fuses.. if there are some for that..

The 12V accessory fuse (beside the lighter) controls the OBDII port, IIRC.

You are probably correct..

Alright thanks! That is probably it. I forgot to add to my post that my lighter port doesn't work either

AND it must be CANBUS Compatible. A regular OBD II scanner will not work completely with the LS.

I have an old OMNI Nova OBD II scanner and it will talk a little with the LS but mostly doesn't give me any useful codes. I think all it does that is useful is that it will reset the codes, but I forget since I don't use it anymore.

Good Luck,

CAN compatible is required for gen II, but not for gen I.

I was wondering about that but he didn't specify. Since he wasn't getting scans I figured he had CAN.

Should have put in a disclaimer for pre 03.
