Why Won't our Pneumatic System Work!!???!?

We have been struggling really hard with our pneumatics system for the past couple of days. We have literally tried everything, but still when we enable the robot, the compressor doesn't start. I'm going to list everything we have going on related to pneumatics with our robot. If someone can PLEASE tell us what we're doing wrong, you would be a LIFESAVER!

CODE:

We code in Java. The compressor constructor reads as follows
Compressor compressor = new Compressor(2,8);

Inside the robotInit method, we have the following
compressor.Start();

The code properly compiles to the cRIO.


Our Compressor is wired to a spike. When plugged in, the light on the spike is orange, which we read is the correct color. The spike goes to the PDB. It is also wired via PWM cable to the Sidecar into relay #8. The Pneumatics are set up according to Team 358 (Happague)'s instructions. The pressure switch is wired via PWM cable to DIO #2 on the sidecar.

According to our (painstakingly extensive) research, when we enable the robot, the compressor should start. We aren't even worried about firing the piston yet. If you see anything in here that seems WRONG, or somewhere where we might have done something stupid like plug a cable in backwards, please let us know.
