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.

My 1999 aruora secrity light is blinking and my car wont start. If it does it only runs for bout 3 sec then dies again . Thats only when its been sitting for a couple day . Nobofy can figure out whats...


Sounds like a problem with the security. It immobilizes the fuel injector circuit when the security is on.

Try this: turn key to on, and wait several minutes (up to 30 minutes) to see if light stops blinking. If it does stop, turn key back off, then try to start it. If the security light goes off, it may have reset. If it does not stop blinking or staying on steady, the dealer will charge outrageous prices to fix it-possibly over $800. Google "passlock bypass" or "passkey bypass" or "VATS bypass" to see your options. A site called newrockies sells a module (about $200) that forever bypasses the whole security system.

Car run cut off when im riding


You'll have to figure out if it is a fuel or ignition problem.
Is the check engine light on ? Have you checked for trouble codes ?
It could be a relay, the ignition module, coil, fuel pump, or a list of other things.
