Its your engine to chassis ground I had same problem replace wire or try sanding paint around connection for better connection. The wire is located on top left of engine, very visible
This might work for most:
Theft Module Re-learn Procedure without a T5O or T6O
During this procedure, the vehicle battery must maintain a minimum of 10.5 volts. If the battery is not fully charged or is weak, a battery charger may be connected.
NOTE The battery charger must NOT be set in 12 volt boost. This will prevent this procedure from working.
1.
Cycle the ignition switch to the "Run" position.
2.
Wait a minimum of 10 minutes, cycle the ignition switch to the "Off" position.
3.
Cycle the ignition switch to the "Run" position.
4.
Wait a minimum of 10 minutes, cycle the ignition switch to the "Off" position.
5.
Cycle the ignition switch to the "Run" position.
6.
Wait a minimum of 10 minutes, cycle the ignition switch to the "Off" position.
7.
Verify the repair.
and if not try this:
STARTING DISABLED/DUE TO THEFT SYSTEM/REMOVE IGNITION KEY"
If the Powertrain Control Module (PCM) does not receive the Fuel Enable message it will use the class 2 serial data line (CKT 1807) to tell the Instrument Panel Cluster (IPC) to display the "STARTING DISABLED/DUE TO THEFT SYSTEM/REMOVE IGNITION KEY" message on the Driver Information Center (DIC) . This will inform the driver of why the engine is not starting. When the ignition is turned "OFF", the IPC will start a timer and display messages to inform the driver to wait for the PASS-Key II timer to run out. The messages will read "WAIT 3 MINUTES", "WAIT 2 MINUTES" (after 1 minutes has passed), "WAIT 1 MINUTE", and "START CAR".
If the timer was not run out, the IPC will not send the Fuel Enable message. When the PCM does not receive the Fuel Enable message, it will command the IPC to re-start the message process.
This message is most likely caused by an improper key resistor value or the IPC did not properly sense the ignition key resistance.
good luck!

Try to reset the p.c. by unpluging the batt. for 10 min that should do the trick.
SOURCE: '97 Cadllac Deville Concours reading "Anti Theft System Problem"
make sure your key is clean try again, if not the system will tell you to wait 3 mins while key is in ignition this will reset the system and dash will tell you to start vehicle, you should be fine after that, common cause dirty key!!!!!!!!
