Don’t suppose it’s in gear ? Some and probably most engines of the last couple of decades, have an in gear interlock.

Ha Ha.... thats exactly why my Nannis would not start, same symptom!

From the circuit diagram, the starter relay has a brown cable running to it (amongst others) and the pre heat relay has a yellow cable.
Hope that helps.
