How to diagnose a cylinder misfire
First do a compression test on that cylinder to verify there is no internal engine problems and compression on the misfiring cylinders is the sameas the other cylinders. If compression is good verify spark on that cylinder is as good as the spark on the other cylinders if not replace the spark plug and wire, if spark is still weak replace coil. If problem is still no or weak spark then you have a wiring problem on that cylinder. If spark is good use a LED testlight to verify the circuit has good power and ground pulsating on the injector circuit, if not you have a wiring problem if the circuit is working like it should replace the injector. If everything is good up to this point you likely have a leaking intake manifold gasket.
Cadillac sts 1993 4.6 northstar: when my fuel tank
The gas gauge is off. The buzz you hear is you fuel pump the pump is a assembly and is quickly draining out.Now for this to stay in first gear and not shift and speed gauge doesnt work. Lets fix that.when the fuel pump works it pressurize the line,it does this so you dont get what they used to call in carburator lines vapor lock. because your loosing fuel and taking in air you now have vapor lock (hence the buzz) fuel isnt pressurized and you are just getting enough to accelerate. so when you turn you run out of fuel and stall at this point .Avoid uphills ,then you ll stall uphill and turns. okay for the speedometer to go out ,Thefuel sending unit recieve a ground resistor value in the gauge you have what they call a voltage regulator in the dash, this regulator does exactly what it means there it displays temperatur value and gas level a change resistant value now short the speedometor and it shorts it out and flat lines it.

Why wont my cadiilac 2002 sts move in any gear?
I hate to be the bearer of bad news but sounds like your transmission has gone out. But shifting to park and no motion is an acceptable behavior:)
One other possibility is the linkage to the transmission has broken and you are not actually shifting gears when moving the shifter.
Tail lights
Hi I'm Peter, Take the bulb out and use a test light touching the center conductor to see if you have power, if you do the you have a bad ground connection.
Reset security alarm
The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.
