If it hasn't run in that length of time and there was no freon in it, you have a leak. I would put in some uv dye and look for the leak, before you waste any more money. Once the leak has been found and repaired, i would run a vacuum pump on it to get rid of any condensation in the system, then do your recharge, don't forget when recharging dont allow any air in the system in between cans, purge the can first.
I would make sure that the compresser even turns on. Jump the low pressure switch on the Receiver drier, if the compresser turns on and doesn't make any abnormal noise put in another can. My Alldata show'* that our cars, i have the same car, takes 2.4 LBS of R12. That is ( 3 ) 12 oz cans of R134a.
