Is the inside fan working and on high? If not, this will cause short cycling.
Otherwise likely the AC is short cycling because it's low on Freon. Either continue to allow it to fill or jump the AC low pressure switch to force it to run while re-filling.
It would be expected to see the pressure go up/down as the compressor cycles. The gauge reading zero does not mean no Freon.
If this does not make sense to you, strong consideration should be given to using a professional. If done incorrectly, AC work can be very dangerous. Reminder, when the AC system is working like it should, Freon does not leak out. So where did the Freon go? If the leak isn't found, then the Freon you are putting in will just leak out again. It will also take oil with it which may cause a compressor failure.
