HELP NEEDED: Solenoids not firing

We are using 24V solenoids, wired into the PCM. The PCM is set to 24V, the lights on the solenoid ports (small red ones on PCM) are lighting up, and the solenoids fire manually. There is voltage going to the solenoids (we tested with a voltmeter), but the solenoids aren't actuating.

The PCM is blinking orange when disabled, blinking green when enabled, and blinking red when triggering the solenoids. The red blinks are constant and according to the manual this means a compressor issue. We tried flipping the positive and negative on the compressor but that didn't change anything, the compressor is still filling air because it fires manually, so I can't see the problem. There are also no visual indications that the compressor isn't working.

Thank you for any help you may be able to provide. My team and I would really appreciate it.
