Check the rpm sensor adjustment
The diesel will start and idle but will not rev
The lp or gas will not start
Are there any codes ? If no codes
Ck rpm sensor , seat switch ,brake switches
There are two switches on brake
One normally closed one normally open as I remember those items will give you that issue

Yes it does everything lifts/tilts just on tick over , it just wont rev up so then it will not drive, yes in the uk, we have a local company that we can get out just would rather have a go first, just its hard when we dont have the software to plug them in

Does it lift or tilt at all?

If no it could be the seat switch, or could be throttle potentiometer needs calibrating/replacing.

Where are you in the uk?
