Check for voltage at the gas valve, look in MI's. If present, sounds like gas valve knackered.

Edit; does this have a pilot that is lit first electronically? If so could be pilot injector blocked.

Corgi job though.

yes its electnic ignition, and cleaned that, wat MIs, it did work for a bit then goes off and does wat its doin and its stayed like that since

Gas valve has twin solenoids check for 240 at connections if there is swap them over if the pilot then lights and no main burner you then know it needs a new solenoid.

If APS was faulty it would not get as far as sparking.
