ok ill try that today thanks!

RE: 98 Deville Wont Start!!!
 

disconnected the positive cable from the battery for about 5 minutes, no change.

again, the security light is not on, just the DIS message as i stated in the first post. something i did not mention before is that the relays in the engine bay are clicking, but not the starter or solinoid. the DIS message does not flash untill after i try starting it; first try it acts as normal with no sign of a problem. DIS volt metter is showing 11.5-11.8 volts.

i have been told that it could be a ground somewhere in the engine(did not specify which one), bad lock cylinder, wire/s on the lock cylinder, or a code in the computer that needs to be cleared.

is there any way to troubleshoot this thing so that i dont start buying parts that i dont need. thanks

Normally we disconnect the ground not the positive. I am going to suggest again that you make sure the ground connection is clean and tight.

You can get the codes from the DIS. The link below has the procedure and list of codes for your car.

thanks it was actually the positive. . . cut it back and stripped it down and now it is working. . . definitely need to replace the entire cable in the somewhat near future because the entire cable seems to be a bit corroded. Battery is running a steady 13.6 now! Appreciate all the help!

Security System Problem Engine may not restart
 

Hi, im new to his forum and im hoping to get answers fast. I have a 98 Cadillac deville. ive owned it for a year now and have not had a single problem out of it. until recently my door was kicked out of alignment and i had to take door off and on to realign to get it to shut properly. after finally get it aligned right. i got in my car to start engine and the security system problem engine may not restart came on. also all doors was closed but the dash kept reading door ajar. is it possible that maybe i tore a wire in the wireing harness to the door and cause this security problem to pop up.

The door switches are wired into the security system so make sure all your connections are good and the switch is working, the front door lock cylinders are also equipped with switches to disarm the theft deterent system. when the lock cyinder is turned to unlock the door, the switch grounds the disarm input to the PZM (body control module). *thats right from the factory service manual*, good luck man !)
