    We’ve put another ecu on it and another injector driver but it still gets constant power everything apart from the battery leads are unplugged from the boat and it’s still got power to number 4 injector

      I guess I do not know anything about those HPDIs, but I thought most injectors had power to them as long as the key was in the on position and then the ECU or driver grounded the return wire to open the injector.
      apparently those HPDIs are a lot different
