You can reset the system by turning key to on position for 5-10 mins and then try starting it but its probably a short or grounding prob try the engine to chassis ground

On your key is a diode. Ohm test it . Your ignition is expecting to see that ohm. You can try to reset it by turning key on( no crank) for 10 min. Then turn off and repeat a second time. Then try to start,might work. 2 options replace ignition ( not so cheap on this model) 2nd option ohm key and build resistor to match. On steering column there is an orange wire going from column to bottom corner of wire harness above drivers
left foot. Inside that orange wire are 2 white wires. Cut and wire in resistor to the white wires on harness side not column side. System bypassed, now you can make a dollar copy of key not the 50$ key from dealer and never have the problem again

I put a new stater on my 1992 Cadillac Deville and the iginition still wont turn over.....can somebody tell me what else could be the problem...Thank you


These cars are equipped with an ANTI THEFT system. When this system starts to fail, it goes into antitheft mode and disables the starter, Look for a light on the dash that says SECURITY, If you see this light, then that is your problem. This link will help with that

1997 cadillac deville delagance - anti theft device


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....

DTS won't start after I changed battery.


Likely the PassKey system is in lockdown mode. You may need to take it to a dealer. I seem to remember something about turning the steering wheel back and forth while turning the key on some older models that had an ant-theft column... you might try that.
