Those piercing cans suck
The new self closing ones not much better
If the can does not provide e ough pressure in the low pressure side to start the compressor cycling you can try a few things
Hold the can way up high and turn it upside down
Jumper the low pressure switch
This will cycle the compressor and it will start sucking in refrigerant … after it absorbs a few ounces it should start to short cycle the compressor and suck in the fluid on its own
Hood sticker will tell you how much r134 to add to an empty system 24-30oz somewhere in there. You only need to add oil if you using new compressor imo. I usually add a can of all in one like arctic breeze with stop leak and lubricants and synthetic cold agents etc etc those cans work really well and then follow up with the cheapo wal mart r134. Plan to return some cans hen the nozzles don’t work… so buy extra
