It is a mute point because you can't do this yourself. Your system has air in it plus moisture. All that need sucking out with a refrigerant gas recovery machine to create a very strong vacuum, then the system is checked for leaks. Only then is the refrigerant gas installed by weight. Freon is the brand name for a gas that is no longer used. There is a sticker in the engine bay that tells you the weight of gas and the amount of oil. This explains, take it to a shop that does AC. https://www.fixya.com/cars/r29878326-recharging_vehicle_air_conditioner ..

Brother, it's just the fact that there is STILL air in your system. Just fill the master cylinder, open the left front line and let it run into a bottle to catch it for a bit until you know for sure all air is gone from that line. Then do the same with the right front. Then the left rear, then right rear. This is gravity bleeding, no pumping required. It's the only way to know for sure that each wheel cylinder and line is free of air. Only let the master cylinder drain down about half way each time the tighten each bleeder. Refill with the drained fluid. Be patient my friend, it takes time to do it right, but it works for me every time. Good day.

It could be several different problems. If you want to guess then start with the drivers master switch.

How long since overall tune-up? Use a gage and check proper fuel pressure, key on engine off. vin K 48--55 psi. Also, check that the fuel pressure will hold for bit, with the key off. Check fuel trims when problem is ongoing, see if trying to add or remove fuel? If temp related check the coolant temp sensor. Over-fueling on a hot engine can make it hard to start. Pushing the pedal to the floor should put it in "clear flood mode" and help it to start. Could be other issues?
