I have a 95 olds Cutlass Supreme that wont start every time. When the key is turned the dash lights, headlights, and relay clicks out under the hood but engine wont crank. I replaced the key(resistor chip inside) but still occasionally wont start. Sometimes when this happens it may start after a few minutes and sometimes not until the next day. The security dash light stays on when car is running. I tried to reset the security system by turning key to on posistion until security light goes off but again no go. Does anyone know what would cause this and how to fix it? Any help would be appreciated.

Optional Information:
1995 Oldsmobile Cutlass Supreme 3.1 Liter
