There could be 10 things wrong with it.

Start with all the fuses (easiest)
Check freon pressure with gauges.
Go from there.

how may lbs. if you can tell? Also disconnect the connector from on top of the freon line into compressor that has a black/white and dark blue wire attached to it. Short the terminals in the connector and try again. If it activates then either that pressure switch is defective or the freon charge is to low still.
