Re: 1999 sts wont start

Check the shift quadrant on top of the transmission - where the cable attaches - right in front of where your gas pedal toes would lie - under the hood, at the firewall.

Next is the neutral safety switch - not sure about a '99 - ask N*Caddy.

last is the IMS - Internal Mode Switch - on the valve body inside the transmission: pan drop, valve body drop. Not fun.
