The sensor in the hydraulic valve block may be faulty or the shuttle vale could be stuck. If yuo remove it and place close to a metal object you should see the LED illuminate and the truck will operate. Had one where the armature on the hydaulic motor was sheard off so there was no pressure to operate the shuttle valve.
There is diagnostic software available for these trucks.

The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
