I have a 2005 hydaia accent that crank up but won't stay run but when I put it in drive it kills

Check the crank case sensor

Only one bad door switch should do that

The 20 min time out is the GEM or Body Module,
which is normal only because you have a bad switch,
otherwise it goes to sleep when either front door opens

Put radio on & open a door,the radio should go off
& kill the time delay if no issues exist

Please explain.
You can't add freon ?
The freon won't stay in the system ?
You know the engine and the compressor has to be running to add freon, right ?

First off remove the ground cable from the battery and at the body mount and CLEAN both area that the cables ground to
charge the battery fully and recheck if the car will start

You'll have to figure out if it is a fuel or ignition problem.
Check and see if you are getting spark to the plugs first.
Also re-check the computer for codes and see how many are back.
Trouble codes are suggestions, not solid instructions.

Pull that fuse or pull tail lamp relay, that should kill the lamps till you figure out the problem? You also have left an right tail lamp fuses, underhood fuse box. I don't know if tail lamp relay is faulty? Another concern, see the bottom wire on left of tail lamp relay, that is a ground controlled by the headlamp/multifunction switch, there could be a problem with that wire circuit or the multifunction switch. At the moment, I'm hoping just faulty relay.

When you turn the key on the ASD relay should turn on the fuel pump and power the injector, Do this lets cheat the system go to the ASD rely open the cover expose the inside have some one turn the key on does the ASD make contact? If not turn the key on collpase the ASD so it make contact do you hear the fuel pump come on? Now try this just as how you iopen the ASD do the same to the starter relay. Put the car in gear e brake on someone in the vehicle in case the car start and you are in front of it and it runs you over so at least they step on the brakes. Key on ASD exposed as your collapse the starter relay does the ASD relay turn on? Here why if you can control all the relay from under the hood you will need a ignition switch (the eletrical part)

Done cars have a kill switch if they are low on oil. Check your oil. If the oil is good, it may be the ignition switch.

If the engine fires up for a second or two with starting fluid then the fuel pump is weak.I would check the fuel pressure and if its not within the specs then replace the pump and filter.

Define - It attempts to turn over but won't catch and run ???? When you turn the key to start does the starter engage an spin the engine ? This would be a crank no start condition . If the starter doesn't engage an spin the engine this would be a no crank no start condition . Sorry to ask but i have only been an auto tech for thirty years an have heard a lot of different discriptions for these simple actions . crank no start or no crank no start . Very different diagnostic procedures . So when you turn the key to start , does the starter engage an spin the engine ,but won't start an run ?
