You may have a failed ignition lock cylinder The wires that are attached to the lock cylinder are probably broke therefore the resistor value of the key pelet is not getting to the theft system module there fore without tha signal the car will not start. to repair the car will need a new lock cylinder and at least one new key

SOURCE: my 1990 cadillac seville says

This happens when there is a break in communication between the chip in the key, the ignition, and the TDM (theft deterrent module). When these parts are not communicating properly, the antitheft system locks out the starter. Without the correct signal being sent completely through the system, the car considers it to be an illigitamate key and shuts down the starter to prevent HOTWIRING and eventually theft of your vehicle. Its a good system when it works properly. The problem can be as simple as a worn out key or as serious as a bad TDM which can run up to $1000. There are ways around this system for a cheaper cost, this link will help you troubleshoot the problem and educate you on the system. There are also some links to help you fix this yourself. This is a very common GM problem, so you are not alone in this.

I Have A Seville 1990, When That Happen To Me I Got The Inginion
Replaced Problem Solved. What Is Happening Is Your Key Has A Chip And That Chip Is A Resister And When The Valve Is Not Sented To The Computer It Disengages the Fuel Pump And Than Tells You To Wait. Soon All That Will Happen Is You Will Get The Wait 3 Mins And It Will Never Start, A Good Locksmith Can Take Care Of This For You And That Will Save You Some Money. Cause If You Go To The Dealer Ouch They Will Hit You Up. But I Asure This Is How It Will Happen Cause It Is How It Happen To Me
And Sorry There Is No By Passing The Computer

You have a broken wire in the steering column. there are ways to cheat, but to fix it right, the dealer is the best option. Cost will probably be in the 400 dollar range for a new ignition tumbler, install, and programming.

Cadillac seville won't start due to theft system


If you know how to solder, you can try building up the "chip" area on the key and reinserting it. That's the only thing that controls the PASSLOCK theft system.

Measure the resistance from one of the contacts to the other with an ohmmeter, and you can get those keys from eBay. Once you get the car home, order one for a couple bucks, and get it cut at your local hardware store.

When you order the new key, they will ask you for the resistance measurement across the resistor embedded in the key, and send you one that matches.

If you'd rather order one from the dealer, they are still available last I checked, but were significantly more expensive than the eBay option.

Replace the ign. lock cylinder and chip key to fix it. Or get a new cylinder and put old chip key in it. Connect it to orange wire at the lower part of steering column and with a copy of the original key start car

Cadillac seville won't start


I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)

Starter disabled due to theft system


the wire that goes to the ignition to the anti theft device is probably broken if you call a good locksmith they can go in through the steering column and fix it same thing happened to my 95 eldorado apparently cadillac designed the anti theft system to coincide with the ignition and is connected to the ignition with two wires that turn as the key is turned the wires twist and eventually they wear out
