    If the chip in the key is in good shape, then it's probably the ignition lock cylinder. There are 2 small wires attached to the lock cylinder that are prone to break after years of use. Don't try to fix it yourself! It takes experience and special tools.

  • If you are experiencing an intermittent no start condition you probably have a bad ignition lock cylinder the two wires that come off of the cylinder tend to break due to normal use.
