I recently had a problem with my 95 Monte Carlo after I changed out my turn signal switch. I got it back together and it would not start when I turned the key but everything else worked ok. I checked and double checked the connectors, checked and double checked the security system, and even broke down and put in a new ignition switch. I had searched earlier postings on this site and got some good ideas about how to bypass my VATS but nothing I had not already checked. Finally I thought the only thing I hadn't done or reconnected was the two airbag fuses when I had the steering column apart. I reconnected those and it started. I just wanted to post this in case anyone had the same problem sometime. I would have not guessed it was related at all.
