Hi there, you are quite correct - it should not run with ign off. I just went and redid it so that the +ve side of the relay goes to a switched live instead of perm live. What now happens is that when the ignition is switched on the pump runs for about 3 seconds then stops (I think this is correct?). Still not getting any spark or sound of injectors firing. Think I am getting CPS signal because when I stop cranking the pump runs again for a couple of seconds - I assume the pump will run when the cpu sees crank pulses and the rail pressure is low?
Bloody witchcraft
