Does my 2004 cavalier have a fuel kill switch

This may be related to the antitheft system. The system is known for turning off the starter and/or injectors when it fails. Normally when the injectors are turned off, the car will run for a second or two, and then stall. When it's the security locked out starter, you won't even hear a click when you turn the key. Is there a light on the dash that says SECURITY or a picture of a car with a lock through it? This is a common problem worth looking into. Do It Yourself GM Security bypass

I have a 2003 Chevy Cavalier, when I turn the key to accessory pos, all dash lights lit and fuel pump runs, but, when I turn the key, all gauges drop and nothing happens but a weird hissing sound?????

Where is the hissing coming from? Could it be coming from the engine compartment? Maybe the starter is spinning, and not engaging. Have someone turn the key and you watch and listen to the starter.

The engine in my 1984 firebird wont stop turning over after key release

If you are talking about engine cranking, then you should check for free operation of the starter motor solenoid. This is situated on the top/side of the motor and it\'s job is to engage the starter motor only when the ignition key is turned to the crank position. It is plausible that the solenoid has become corroded, or fused in the closed circuit position.
To check to see if this is the case, remove and clean the starter motor solenoid, and test it\'s operation while off the car.

If you are talking about continuous running, not cranking, then you will best use an endoscope and insert it into the engine\'s cylinders to view the innards. You are looking for a build up of carbon on either the valves, valve stems (when in the open position), pistons, and cylinder head. Also check the condition of the spark plugs for a build up of carbon.
Carbon is a byproduct of combustion, and can build up on some internal engine surfaces. This can cause a number of issues when running. The carbon becomes red hot and can retain it\'s temperature for a long period of time. When you turn off the engine in a carburetor vehicle, then air and fuel can still be drawn into the engine while its momentum winds down. However as the red hot carbon in the cylinders is hot enough to ignite the fuel and air mixture, the engine still runs, still turns and continues to suck in more air and fuel mixture, and continues to operate.
It may operate quite roughly and eventually stall out, as the fuel/air mixture isn\'t as efficiently burned when ignited by hot spots, and the hot spots may eventually cool enough to fail as an ignition source.

These two above examples are perhaps a couple of the most common reasons for an engine continuing to run after the ignition key has been turned to the off position, or has even been removed from the lock/barrel.
The only final reason for the engine managing to keep running after the key has been removed, is a faulty ignition lock/barrel mechanism.

My 2004 cavalier will not turn over without excessive pumping of the gas pedal. Battery, starter and everything else seems to be fine. Is it the pump or something else?

Try this next time you start it. Turn the key to the run position, do not start the engine. Wait 3-5 seconds and turn the key off. Turn the key right back to the on position and wait for 3-5 seconds. Turn the key off. Repeat the above one more time. Now try to start. If it starts right up you have a fuel supply problem. Either the fuel pump is bleeding off or the fuel pressure regulator is leaking. Pumping the pedal is doing nothing besides buying time for the fuel system to pressurize. Post an engine size and I'll help you locate the fuel pressure regulator. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

Motor stops running after starting

You might also find that the fuel filter is in need of a cleaning. Sitting that long can lead to a bit of rust dust in the tank, specially if you have given it a push.
