Question
i have a 98 sts and when i try to turn it over evrything go black gages everything voltage is good its not sercurity, the starter doesnt even clik
Hello,
Unfortunately, to try to answer your question with any accuracy without being at the car is almost close to impossible, but I will throw some things out at you.
A ground issue could be the cause under the hood. Check all grounds to make sure there is good contact. Check near the starter wiring harness for a blown fusible link. This is a wire that acts as a fuse which could be consistent with your problem. Checking for such a problem can be difficult because of access.
If you can get access, pull on the thick red wire leading to the starter. This is battery power. If it feels rubbery, you have a blown fusible link.
The other fusible link location I have run across in many cars is the red wire going into the alternator. Fusible links control power to the vehicle.
This situation you have really merits a professional.

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?
