Question
My Passkey II system failed a short while ago. Although the starter runs, the car will not start because there is no fuel pressure. As you may know the trick with installing resistors under the dash to override the key, I did that. So the only other thing I've figured that I can conclude is wrong is the VATS module itself. But I can't find it on my 1996 Deville Base model. Can you help me locate it so I can override it?
Hello,
You have something else other that the vats going on here.
The module should be behind the gove box. you may have to remove the pass air bag to get to the module.
What you need to understand is that not only is fuel shut off but there is injector pulse as well.
I would be looking at this forgetting about the vats, this is not the problem with your car. If you bypassed and it cranks, it is something else. You are chasing ghosts. No matter what you do with module, you will have the same problem.

Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
