Question
I have a Cadillac Deville and i drove it for a while then i parked it when i went back outside to start it and you could turn the key and i wouldn't start after a couple of trys it would start now there is no power no dash lights nothing it will not even crank I've checked the battery cables and still nothing the battery is good i have had it checked out now the car has been sitting for a week and i need to know whats wrong. The car has an aftermarket alarm with remote start and it wont start using the remote to start it.

Answer
Hello,

Without being at the car it is impossible for me to give you an exact answer as to what may be wrong.
However, that does not stop me from considering your complaint.

No power with the battery being good is consistent with 2 types of problems.

Either a distribution box under the dash that has connection problems or a burned out fusible link under the hood.

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?
