PCM not turning Compressor On

So our pneumatic system has been acting very strange. We have switched PCMs, pressure switches, and wires. The PCM always has its status LED blinking green but the COMP light never turns on when the robot is enabled. We have tried shorting the pressure switch terminal with a wire and it still never turned the LED or compressor on. The compressor does work when directly put to power. Any help is greatly appreciated! Thanks!

Wait, nevermind. I uploaded new code that had Solenoid Objects in it. That activated the PCM.
