Hello and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
The code: 83-01 ECM to PCM module relay malfunction could be related.
If you put a jumper in the compressor clutch relay, with blower on, do you get cold air inside, and is the compressor engaging?
did you check the PCM connectors? (tight and clean contacts)

The compressor comes on does not pump any psi.

is the system charged? is was the expansion valve replaced with a OE unit? and when powering the a/c clutch, are you also activating the variable capacity control solenoid o nthe compressor? this also should be powered so the compressor operates successfully...
