I would start with vacuuming and if it holds vacuum add 1 can that has dye and only dye in it.
If it holds the pressure for couple of days, than add 2 more cans.
With EC light on the computer will not engage the compressor, so you need to clear the code in order for compressor to suck R134.
Here is help page you could find in stickies.
