      I think I may know the issue . its really common in gm cars. I have had it happen.. check out this site they explain the issue and how to fix it
      hope this helps
      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.

      The most common cause of overheating is because of an external leak from a water pump or a radiator or heater hose. The way to find the leak is to wait till it is overnight cold and maybe just pour water in and see if the leak is large enough to see it simply leak out from where it has a leak. if you pour in a half gallon or more and you still see no leak its time to pressure check the system.

      Here is a short list of possible causes for overheating;

      Low coolant level
      Leaking coolant
      Improper coolant concentration (not at recommended 50 / 50 mix of anti-freeze and water)
      Clogged radiator hoses
      Clogged heater hoses
      Clogged radiator passages
      Clogged heater core
      Faulty thermostat
      Faulty water pump
      Faulty radiator cooling fans
      Faulty radiator cooling fan switch (coolant temperature sensor)
      Faulty / worn serpentine drive belt
      Faulty / worn drive belt tensioner

    Why does my car die a minute or so after starting it ?
    After I start my car the engine slowly dies and stops running . If I start it again it will do the same , but if I go and push the gas it will go away and the car will then run fine . Why is this ?

      Spray some aerosol starting fluid into the throttle (CAUTION: Starting Fluid is Extremely Flammable!). Then crank the engine, If the engine starts until the starting fluid runs out, then you do NOT have an ignition problem.

      Have an assistant to turn on the ignition switch, while you listen to the fuel pump running for 2 seconds from the uncap fuel tank filler. No noise, take the next step.
      Try giving the bottom of the fuel tank a few whacks with a flat piece of wood or a rubber mallet while another tries to start the engine. You have a 50/50 shot at getting the pump going again and the vehicle starting. if it starts as a result of the whack then it confirms the bad fuel pump.

    1997 Pontiac GrandAM 2.4, when it's running it is not running hot,
    but when it is setting idling you can hear a sound like steam and acting like a valve is opening and closing it seems as thou it's coming from where the plugs are or at the backside of the engine

      The headlamps staying on for a bit, should be a safety feature? They should time out after a bit? You have right and left headlamp fuses in the under hood fuse box, pulling those fuses should kill the headlamps.

      I don't know if there are applicable lighting trouble codes, some of the national brand auto stores will check codes for free. If you have lighting trouble codes, it would probably be manufacturer specific codes, not p0 codes.

      You have drl relay and automatic headlamp relay,

      Check for proper fuel pressure, check spark at the spark plugs. Check for a clogged exhaust. Check for applicable trouble codes. To check codes yourself, at the least, you need an obd2 code reader.
