A code 12 means a bad electrical connection or weak electrical system such as low system voltage.

If it has anti theft system activated, it will start briefly then computer will shut it down. Deactivate by unlocking either front doors with key, or if system is malfunctioning, you can ground the ground wire running to the theft module(21 pin natural color connector)under the dash above the glove box. I put in a permanent wire with a momentary switch, so whenever the theft system is activated, I can just push it to reset system.
