If it is an older model with a 4 barrel carborater remove the top of the air cleaner leave the motor off puch open the top flaps on the 4 barrels (back 2) and then take a screw driver and tap on the flaps at the bottom sounds like the secondary flaps are stuck open slightly this is common on older cars because they may have not been kick open in awhile.

If your engine has a carburetor, a small amount of fuel will be sprayed in to the intake manifold when accelerator is depressed, and engine isn't running. This is fuel stored in the accelerator pump reservoir to prevent hesitation. So if the engine isn't running, it will spray the first time accelerator pedal is pressed and it won't introduce additional fuel no matter how many times you press the gas pedal after the first press. The engine needs to be running for the accelerator pump well to refill. If your asking because you're wondering if pressing the gas pedal will flood the engine making it hard to start, the answer is No, it won't flood the engine. If your engine does not have a carburetor, then it's fuel injected. No fuel at all will enter the engine with the gas pedal pressed, engine not running. The engine has to be cranking (starter engaged to start engine) for the fuel system to operate. 0 chance of fuel if the engine is not cranking or running to activate fuel injection.

I assume you mean add fuel by pressing the accelerator. In which case the engine runs faster.

Yes, a broken or disconnected accelerator cable is the likely cause for the accelerator pedal to quit working. The car will still run fine but will not be able to accelerate past idle.

Try turning the key to "on" position without engine running and step on accelerator 3 times

Open your hood and have someone press and release the accelerator pedal while you look for movement at the end of one of the cables on the top of the engine. That is the throttle.
