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.
