There are "steps" on the choke cam that pull the gas pedal up to a high speed idle when the choke is on. If you don't step on the gas pedal once before starting, the carburator/choke assembly cannot function properly.
It is a carburetor where the engine coolant is routed through the choke system of the carburetor. When the coolant is cold the choke will close. As the engine coolant heats up it opens the choke.
That part is called a bimetalic spring with housing the purpose of this part is to coil up in cold temperature and uncoil when heated, that cause the choke blade to open and close.

Check the choke throttle and linkage for binding that won't allow the choke baffle to close partially when you let off the gas. A good carburetor cleaner will dislodge any gunk or goop - follow the instructions on the can.
The choke light on a 1984 Chevy El Camino will come on if the choke fails to open or close. The choke should be visually inspected to verify functionality.
You need to take you car to a mechanic. It is obvious you do not know what you are doing. Your battery is in the electrical system. Your choke is in the fuel system. They are separate. It is normal to pull out your choke to start your engine. It is not normal to have your choke out to run your engine. As soon as your engine starts, you should push your choke in. When you pull out your choke, you close the air going into your carb. Then you push in the choke to allow air to flow through your carb. That lets you speed up or slow down. If it won't run with the choke pushed in, try pushing the choke in slower.
No thay are not, no where close
Close choke (if equiped), if not, consider servicing the carby or the fuel pump. * This answer is answered in assumption that it runs after start. If you have to put petrol down the carby to keep it going, consider servicing/replacing the carby
The choke spreads fairly quickly and is use for upland hunting such as: quail, rabbits and close range game.
