I need some advice on how to get my check engine light functioning. I've done a bunch of searches here and can't find the exact problem I'm having. It's a 92 Camaro, TBI, 305. The check engine light does not come on at all. I found one thread about an older model Firebird where they were able to ground one of the pins to check the light, but in my car there is no pin in that location. The light doesn't come on when the key is turned, nor does it come on when jumping the terminals to check codes. The car runs good except for an intermittent stalling problem when driving at highway speeds. We haven't had the car for too long, but everything seems to be stock. I found under the backseat where someone cut a hole to replace the fuel pump at one time. Other than that I can find no other modifications.

I also pulled the gauge cluster and replaced the bulb with a known good one and it made no change.

With the car stalling I thought the first, best place to look would be for any codes. Does anyone have any advice on what might be wrong with the check engine light?

Any help is appreciated! Thanks!

 

I thought this would be an easy fix. Kind of suprised that there has been no response yet. Is this just not a common problem? Any suggestions at all would be great. Thanks!

 

Here is a circuit diagram from AustinThirdGen for you SES indicator. There are lots of great diagrams for 92 Camaros. HTH!
ECM wiring from ChevyThunder!

 

I have been digging around and I hate to dig this up but did you find an answer? This does not seem to be common problem.
I have the same problem with my 85 T/A. No burnt wiring, tracks on the cluster are good. It is not any fuses or burnt out bulbs.
