Did some wheeling last weekend and drove home on low AHC setting and it wouldn't rise.

Plugged in techstream today and the AHC ECU is working fine, all the gates work ok, but I get zero pressure at any solenoid.

The motor relay clicks but the motor doesn't seem to start.

Truck has done 60k miles, has had new spheres, replacement front sensors, and a couple of oil flushes. The reservoir is full and there are no leaks. Dash is showing AHC as solid off (and yes I checked toake sure I hadn't pressed off by Accident....)

There are no error codes!

The only oddity is that front left sensor is showing -40mm but the front right is showing -95mm (I suspect this is an installation error!)

Any thoughts?

Suspect it's time for a new motor, but how can I be sure?

Suspect is
