Shes had issues with the security system in the past and I suspect this is more of the same. I think its a 3.9 liter but will have to check.

You can hear relays engage when the key is turned to run then a other when continuing to the start position.

Im trying to find information on how to sort out security system issues from other electrical issues without teariing the whole dash apart and crawling around with a volt meter.

The more i read up on this car the more i suspect its something with the bcm and or pcm.
