If it still has refrigerant left, you can merely top it up with refrigerant and add UV dye at the same time, without pulling a vacuum. The system must be completely charged and running in order for the dye to be able to move around and find the leak.

You can buy 12 oz cans of R-134a that also contain about 1/4 oz of UV dye (but no other additives). Use only one such can per system, or if you're injecting dye directly use 1/4 oz. Don't use more than that.

Leaked down to zero you really should pull vacuum first before charging and operating. But you might try putting a few oz of R-134a in with the engine off to see if it just hisses out somewhere through a big leak.
