Question
I have a 2001 Cadillac deville tonight I went to leave for work and it wouldn't start it didn't try to turn over there is nearly a half tank of gas and the battery is showing 12.1 volts but it wont start

Answer
Hello,

As I stated previously, these vehicles are very complicated and are no longer simple to diagnose. In fact, without specialized equipment, one cannot differentiate from an electronics issue or a fuel issue. Unfortunately, you will have to probably have the vehicle towed some place to have the problem diagnosed. I highly recommend a reputable service facility and never a dealer, in which one pays far too much for the privilege of having the vehicle at the dealer.
Dealers are not anymore knowledgeable than most major service centers that have the same diagnostic equipment as well as the same type of manuals.

Good luck!

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?
