[desperatedes]

Yes the keycode light goes out.been investigating today and as i mentioned before if i give a positive feed to pin 3 on the cut out switch the buzzing at injector 2 from tbelt stops also the brown relay clicks.while the injector plug buzzes the voltage at the plug is 1.6v .enough to make it buzz i presume.
all other inj plugs show little or no voltage.tested wire between cut out and brown relay.all good.tested all live feeds to brown double relay all good and the earth to pin 10.i now suspect the relay as a good 12v going in and only 11.5 coming out.it couldnt be just the relay being duff could it? Heres hoping going to order a new one.fingers crossed.
