Ignition Sometimes, not always, when I turn the ignition key to start, absolutely nothing happens, I turn it back to the off position, then back to start, and it starts up. When that problem occurs, once in awhile it will take 2 or 3 turns of the ignition key (back and forth from off to start). I have thoroughly cleaned all connections at the starter, including the mating face of the starter to the bell housing. Any help will surely be appreciated. Thank you, Mark Gwynn Cleveland OH

I also had a 91 Riviera years ago. I loved that car. Then one day I went to start the car and the security light was flashing and the car wouldn't start. I didn't realize it at that time, but everytime I turned the key to off and then tried to start the car it would reset the security system. I later read the manual and discovered that I had to wait 10 minutes for the security system to clear. It got to the point that it was doing this everytime and I got tired of waiting 10 minutes. I took it in and they ended up replacing the ignition and keys. The chip in the key had stopped working and cost me $600 to repair. I also had a 91 Riviera years ago. I loved that car.

Years ago I had a 91 Riviera and had the same problem. I would turn the key and the security light would flash. I would turn it back to off and the security light would still flash. After reading the manuel I discovered that the security system had been triggered and I had to wait 10 minutes for the system to reset. Everytime I turned the key on and off it would reset the time to 0 and have to wait another 10 minutes. I eventually got tired of waiting 10 minutes to start the car. I took it in and they had to replace the keys and ignition. The chip in the key stopped syncing to the car. It cost me $600 to replace. Years ago I had a 91 Riviera and had the same problem.
