Thanks for that.
I asumed the fuel cut off on the side of air box was working as both lights come on the dash when you let off throttle , but had a listen and can’t hear a click. Tried 2 more and they don’t click, (never checked lights) , is there anyway of checking wires are working ie test light etc I also have a spares for the other sensor valves, is there anyway of checking these before I fit them ? It’s had a new fuel filter and service ,
