Turn the key on for 10 minutes, until the security light goes out. Then turn it off for 5 seconds, then back on and start the car. See if the light goes off. Don't open any doors during this time.
The security system (VATS/PassKey) is having problems, it's typical on those cars and it will gradually prevent the car to start anymore. You can find a great write-up here: http://newrockies.ca , this has been the only thing that saved my Park Avenue.
Looks like the TDM in the security system (VATS/PassKey) is having problems, it's typical on those cars. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.
try disconnecting the wiring harness to the MAF ( mass air floww sensor) and see if it stays running if it does replace it (if not the car will run real rich,burn fuel and leave a cloud of smoke behind you.
you nay have a worn out ignition key pellet or broken wire inside the ignition switch that goes to the anti theft unit and it is being put in a passive mode which will allow the car to start after a waiting period.
