I have a 1990 seville, I am getting a code that reads " starting disabled due to theft system. I have a good battery. I wiated three minutes, as instructed by the message on the DIC. The car still doesn't start. What could be the possible problems?

Broken wires up by the ignition lock cylinder. You can verify this with an ohmmeter. At the base of the steering column there is a large connector that is mated together with a bolt(7mm). With it disconnected, find the two small, white wires that emerge from an orange conduit. With your ohmmeter, measure the resistance across these two wires, in all ranges(accessory is not necessary). You should have the same resistance in all. You should not have O.L, or whatever your meter displays as open circuit. With that being said, if you know, or can figure out, your keys resistance value, you can place a resistor pack of the same value across the vehicle harness side of that connector as a bypass. It would be your option.

GSstacy, I am not sure, does this mean that I have the option, of simply measuring the resistance of the two white wires, and with the readings, replacing my current resistor, with the number reading. Please forgive me if I read into your response the wrong way?

Your current resistor is the pellet in your key. If you have open circuit resistance when measured at the column side of the connector, you need an ignition cylinder and new keys. If you can determine the value of that pellet(don't touch the leads with your fingers as your body has resistance), then you can make a resistor pack(you will not find one resistor of the correct value, I am almost certain), and place it across the terminals on the harness side, this will bypass the cylinder.

Please, can anyone give me some help in removing the ignition lock cylinder on my 1990 Cadillac seville. I have removed evrything down to the cylinder itself, I am not sure of wat I need to do, in order to get it out of the column?
