My 2002 Cadillac DeVille won't start
My 2002 Cadillac DeVille wasn’t running right so I ran the DIC and it showed a misfire code. It did not specify which cylinder was missing so I ask my son to bring over his fancy diagnosis system. He hook up and found that it was the number two cylinder. The next day I went to pull the car into the garage and found he had left the key on and the battery was dead. I charged the battery and tried to start the car, everything seemed like it was acting normal but nothing happened when I turned the key, it would not engage. I then removed the positive and negative battery cables and touched them together then left them off for about an hour and tried to start it again, nothing happened. I then used the DIC system and now it shows about every code is active. Any idea what happened and what I need to do?
