Where do I find the troubleshooting codes for a 1991 pontiac firebird?

[Eric G]

I need to get my car running and am having trouble getting it started and keeping it running. It did run rough and it seemed rich. Now I can't get it running and keep it running. It is a V^ engine with 66,000 miles on it. It's a 1991 Firebird and I can't seem to find the troubleshooting codes on it any where on line. Everything I click into isn't working. Where do I look? My email address is cgibson1955@gmail.com Please help.

do you have a code analyzer and you dont know what the code means? If so what code is it showing.

From the other email that was sent it appears you have fuel system problems related to a number of possible causes. Check the O2 sensor, pressure regulator and condition of your injectors.
