Thanks for the reply. Here is what i have done so far... There is 12v power at pin 30 K67 relay, i can jump the relay and compressor runs. checked continuity on wires from pressure relief valve back to control module, checked continuity from coil side of relay back to module, checked continuity...

I know this is a while ago, but did you solve this? I have the same problem, it appears that the control unit is not sending enough voltage to operate the relay or the pressure relief valve etc,
