Recently had my pcm sent to cardone for their Rebuild and return policy where they rebuild your pcm and send it back to you(they reflash/reskim it there at their shop before sending it back) after the car stopping on me in mid drive aboit twice. I got it back put it on the vehicle, Did the passkey II relearn procedure (4 diffrent times) and the motor just turns over and over until the battery dies. Before i forget to mention, i did a VATS bypass on the deville about 2 years ago after it woundnt start on me for about 2 months due the security system not recognizing the resistance of the key. What should i do? Are there any steps im missing? Should i undo the vats bypass then redo it? PLEASE HELP! ITS STARTING TO STRESS ME OUT!!
