Whenever you add Freon,you are suppose to leak test first.Your compressor is good,you have a leak somewhere.A good place to take it to is Midas,they changed my freon over from the old stuff to the new R-134a,they leak test it first,that is rule 1 when adding freon.

The instructions I have are 20 pages long, look in your owner's manual or maybe someone else will come up with a shortcut.

5v ref goes to several different sensors. Could be a bad sensor, or wiring, or the ECM its self.

You'll need to isolate 5v ref at the ECM and then check the voltage at the 5V REF pin of the ECM with DMM. If you get 4.75 to 5.25 volts DC then likely the ECM is ok, but you'll need to load test.

If a load test of the ECM 5V REF passes then likely a sensor is bad or there's a damage wire... could be anywhere.

Try searching videos from "south main auto". Eric(?) does excellent videos explaining how to. Pretty sure he has videos specific to 5V REF.

Is the engine turning over with the key in the start position? If the engine is not spinning over and you hear a whining noise, the starter is not engaging the flywheel. If the engine is turning over with the starter engaged, the engine has most likely jumped time that creates low or no compression which results in the whining noise.
