Re: i have a 97 caddy on dash a message enable to start...
Have you tried to get your key looked at??
maybe the resistor on it is no good anymore,
or maybe the wires for this system are damaged,
they are two skinny white wires inside an orange sleeve
(that's how it is on my 97 deville)
check under the dash.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

It's the anti-theft system . (SECURITY ) Keeps vehicle from being stolen ! Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II?® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.
Your best bet would be have it towed to a qualified repair shop !
Anti-theft system can keep vehicle from starting , Alarm is for vehicle content theft , open door without key alarm sounds (horns) ! PATS - passive anti theft system PATS enables and disables the engine from starting ,it will not cause the engine to die ! You have some other kind of problem ! If the vehicle engine doesn't turn over an red light on top of dash flashes fast ,then you have anti-theft system problem !
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
Hi Carol , do you mean PATS passive antitheft system ? Locked up your car ,do you mean it won't crank over an start ?
The passive anti-theft system uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user.
During each vehicle start sequence, the ignition key identification code is requested by the vehicle protection anti-theft electronics.
If the key's ID code has been programmed into the system, the powertrain control module (PCM) (12A650) is signaled to enable the vehicle to start.
If the key's ID code is not programmed into the system, or if no encoded key is detected, then the powertrain control module is signaled to disable the vehicle.
The passive anti-theft system communicates the state of the security system to the powertrain control module via the J-1850 communications network data link connector (DLC). The powertrain control modulebased on the communications from the passive anti-theft system, will determine if the vehicle's engine is enabled to start.
The passive anti-theft system differs from the active anti-theft alarm system in that the passive anti-theft system enables/disables the vehicle from starting and only operates with the ignition switch in RUN/START position. The active anti-theft alarm system has perimeter protection capabilities and operates only with the ignition switch OFF. Refer to Section 13-11A for active anti-theft alarm system information.
The passive anti-theft system will be activated and disable the vehicle from starting if any of the following conditions exist:
damaged encoded key
non-encoded key (key has no electronics)
Passive Anti-Theft System (PATS) control module concern
depnding on what type theft system you had? the usually split/ cut!! 2 wires going to the ignition switch on the column under the dash a red and orange and black wire just find those wires and find both ends i can assure you they are there and hook htem back to standard spec's it should start and run then
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! :)
I've got a 97 deville d'elegance that has issues similar to these. Last year the red anti-theft light came on and the car wouldn't start-took it to the dealership and they replaced the PCM? (the main brain for the system) for $900...the guy told us the wiring was so corroded he didn't want to mess with it much. Today the message started flashing on the dash that says "anti-theft problem/ car may not restart" but it still turned over in the driveway a couple times so I am hoping I can reset it. The wiring system is jacked and will probably need to replace the wiring harness completely. Doubt its worth it. Not a secure feeling with 2 babies in the back seat in the middle of winter....
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
