Most common problem with these things is so-called anti-theft, far more effective in keeping the rightful owner from starting his vehicle than a thief.

Key has a chip in it that has to communicate with a sensor in the lock to start the vehicle, but guys don't fool with this, just use a flat bed truck to take what they want or hold a gun to your head. What caused this is the huge price increase with replacement parts, the VIN in the vehicle is destroyed.

Seen some of my stuff that cost less than a buck to manufacture on dealers shelves for around 150 bucks, this is practically criminal and means to buy a new vehicle than repair an old is cheaper. Some guys spend over $150,000.00 to have an old car repaired. Ha, may bring back memories of your first date, but you are still older than hell.

Anti-thief circuits have proven to be not very effective against a flat bed truck or someone holding a gun to your head. They typically give owners trouble when their vehicle ages when if someone does steal it, would be doing you favor. Then they would have all of your troubles.

This is a pcm grounded circuit, you can bypass that.

But if you want to keep it stock, what is preventing you from taking purple wire to resistor and just fooling the VTD (vehicle theft deterrent)?
