Not sure about the way a 6 cylinder goes, but on the v8 motors you should get a code 12, and then any corresponding trouble codes after. Code 12 means no distributor signal, or something, which is normal. I would check the ecm fuse, and the connector itself. Let us know what you find.

Also, what makes you so sure there is trouble codes? Has the light came on and stayed on?

Hey, no problem. As a suggestion, you may want to check into starting with a basic tuneup on your camaro. A trouble code isnt always going to be set for a car running crappy. A code is set only if a sensor or the circuit of the sensor has a problem. A code wont be set for fouled plugs, burnt wires, dirty air filter, etc. Good luck bud!

The engine needs to be Off to get the 12 error code.

Yeah, but he's got the 2.8 v6 which is distributor less. I don't know if it still gives that code but maybe means something else. I dunno.

Wait nevermind if his car is an 83 it's not fuel injected, so it has a distributor.
