1999 Buick Riviera that won't start sometimes. Problem seems to occur when the SECURITY light stays on. When it does this, it won't start. I wait a few minutes, and it will start. If the SECURITY light is flashing there are no problems. The service book says to take it to the dealer. Is there a cheaper way to solve the problem?

The security system (VATS/PassKey) is having problems, it's typical on those cars/years. When the TDM starts failing, it will do it gradually and the car will begin to randomly don't start and then get worse with time up to a point that it won't start anymore. It's been a nightmare for us. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my 94 Park Avenue that has the same security system.
Yep sounds like you need a new headlight bulb The flashing is the tungsten fillament inside of the bulb breifly contacting the broken halves together when hitting it..Replace the bulb and all should be good. Note some times the light may stay on ,, this is because the broken halves arc welt themselves and break again upon cooling after you turn lights off ...good luck
traction switch is located next to drivers left knee on bottom of dash....you should be able to turn off the traction light there by just turning on the traction control.....the security light is telling you that there is a problem with your security system....could just need a new key with a new computer chip....make sure the key is clean and dry when using so it can read the chip....the security light comes on whenever your start the car and stays on for approximatley 2 minutes and then should go out....it is just a reminder....try this and see if it works....lock the door using the power switch on door.....close door and see if the security light comes on....watch and it should go out after about 2 minutes...if it does then your alarm is activated and working....to disarm you need to unlock the driver door with the key...anything else will set the alarm off and the lights will start flashing and the horn honking...after you set the alarm off you will always have to use the key to unlock the drivers door to turn off the alarm and reset the security system.
