Cadillac Repair/96 Cadillac Devile no start,


Hello, I am desperately trying to figure out how to reset the computer on my 96 devile. This issue came about after my battery died, I went to jump the car and all I got was a click. I assumed it was the starter but the starter never showed any symptoms of failure. How do I tell if that is the cause of the no start or if its the starter its self.  I found the relay and am replacing that. If the computer was tripped how do I reset it. Please any help or knowledge would be greatly valued.  Thank you for your time.  



If all you are getting is a clicking, it is either a starter issue r a battery connection issue. You may have to remove the ground from the frame where the negative cable is located. Grind it down to bare metal and reattach, but before doig that, you need to check the starter. If you put a test light at the purple wire on the solenoid at the stater and have someone turn the ignition to start and there is power at the purple wire, the starter is no good. If there is no light, it is a battery connection issue, or the battery you just put in is no good. That is it. There are no other options. Resetting of the computer does not come into play here.

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?
