Al asks. Dear MW: I have a 1997 Chevy Lumina that I can't get started.I can turn on the key, all the lights are on, but when I try to engage the starter it does nothing and the headlights blink off. I can jump the starter with a screwdriver and the car will start but immediately shut off. I'm thinking it's a key code problem, but have tried two different keys. I tried to rent a code reader but they told me the car needed to be running for it to read codes. Please help direct me in the right direction as this is the wifes car and itr's been down a couple of weeks and she's screamin'! Any help is greatly appreciated. Thanks a million and GO 24!!
MW: Sounds like a security issue. That system has a common problem with with the passlock ignition key cylinder. There are two small wires that attach to the cylinder and read the key code. Those wires break. Just trying a different key wont help, it needs to be the correct security number. That number can be read from a tool at the dealer. The way to check if the passlock ignition cylinder is bad, is to go under the dash and check the resistance of the 2 white wires with the key in the ignition. Not sure how knowledgable you are with cars, so you may want to take to a repair shop.
