Good afternoon.
Did you check for two powers to the relay?
You have a control side and a load side. If you jumped the relay at 30 and 87, that is the load side.
The PCM grounds the control side to turn on the compressor based on inputs from the pressure switches.
Did you verify Freon pressures?
I attached a wiring diagram for you to view. Check the fuses listed for power on both sides with a test light.
Check for power to the low-pressure switch as well. The high-pressure switch is a 5 volt sensor. Verify power to that sensor with a voltmeter.
