Is my compressor shot?

All fuses are fine.
Rebuilt compressor last year using kit. Worked fine past year.
Installed 2 new air shocks, front.
Installed new leveling sensors.
Rebuilt air intake block.

Never re-calibrated.

The truck doesn't lift and amber suspension fault comes on after the compressor stops making noise.

 

Riding high again.

Update:

Removed front air valve block and 'cleaned' a bit and reinstalled it.

Disconnected battery and removed all suspension fuses and performed a hard reset using a 14 gauge wire method.

Let sit 10 min after hard reset and suspension started working. Took a while to fill all the bags but eventually she's riding normal again.

Amber suspension light with suspension fault msg appears after a few minutes but she rides fine.

 

...first thing I'd do is recalibrate.

 

Plan on it...
