Question
Just recently purchased a 92 StS, and for some strange reason it starts when it wants to! Once the car starts, it runs good but then if i shut it off and try to crank it again it takes a couple of time's of turning the key before it starts up.I checked the car again their are now displays on the dash bored, the power seats don't function and their is nothing on the dash board.It actually displayed wait 3 min which i did and during the time i heard little noises (like tapping not sure)so I'm lost. The car is lovely an i don't want to give up but its destroying my train of thought. I drove the car took it up to 100mph the engine is still very strong I'm just puzzled as to why the car doesn't start I'm sure if it get a jump then it will crank 123 but the problem will remain, I'm not sure if its something with the key or electrical or even the alienator. To my understanding if i remove the positive cable on the battery while the car is running an it shuts off then the alienator is bad but I'm almost positive its not that.The car just has a mind of it own i guess, i their is anyone out their who can help greatly appreciate it! ?Thanks a million.

Answer
Hello,

I do not get paid to answer questions here. I share my knowledge to help people.

I told you I had no idea as to where to start with your electrical problem because you have more than one thing not working correctly. Anyone giving you an answer on the web as to your electrical problems is just guessing and I did not want to make such a guess because it would cost you money ans still not fix the problem. I also tried to save you from hurting your car any further by disconnecting the pos battery cable with the engine running.

I really do not appreciate you giving a rating of 1 for knowledgability.
Very few do this and most are very appreciative.

One of these days, I am just going to quit helping anyone.

Some of you people think you havt cars built in the 60's and 70's where they can be tinkered with. Tinkering electrical on a computer controled car can be very costly.

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?
