To make a long sotry short - my 1997 Lumina just died on me about a week ago. I got it towed and it turned on later that day. The mechanic still changed the 02 sensor since it was bad. Then it died on me again while I was driving and hasnt turned on since (about a day so far). It doesnt even try to start the ingition. Its totally dead with no noise at all when I try cranking it. The strange part is all the dash board lights are on and blinking (service engine soon, antilock, etc) even when I take the key out of the ignition. Does anyone know what the issue may be?

Thanks.

Wild guess, your ignition switch bit the dust.
