Welcome, I'm Chris (aka Moose). I'm here to help 365 days a year, but not every hour of the day. I try to prevent delays as much as possible. Please understand I am not there and can only advise based on what you tell me. Let's get started.
Would you like me to help?
Here is your wire diagram. https://www.dropbox.com/s/gn8twcml0owj5xr/40AC.pdf?dl=0
The PCM needs to see a ground from both pressure switches. At the cycling pressure switch is the black/yellow wire grounded, tested while plugged up?
The PCM needs to see a power on the violet wire from the HVAC when AC is commanded on. Check that at the HVAC or PCM.
Once the PCM gets these inputs it will provide power and ground to the WOT relay to energize it.
Did you pull a vacuum on the system prior to attempting to refill with freon?

The link expired because the post was never rated and timed out. Once rated I can get another link back active. Check the violet wire at the HVAC to see if it not powering up with the AC commanded on. If not then the HVAC controller is bad.
