put a brand new pump on it, cleaned out pick up pipe so it was nice and clean, i didnt run any oil through the pump though when i fitted it, i spun the engine over for a while with the king lead off, turned over ok, when it runs it runs quiet and if reved up abit the light goes out but stays on at idle, but the gauge is only showing about 1 bar at 2000 revs so i'm not gona run it any longer until its sorted, thinking i should have run oil through the pump first before fitting it.
