Hey all i have an aussie 2004 d22 zd30. I have had the fuse in the engine bay called ENGCTRL 3 20Amp fuse pop on me twice now in the past few months. I wanted to know what components it is protecting so i can start fault finding? Does anybody have a wiring diagram for that fuse or know wat component it is loking after? When it goes engine stops but everything else stay normal. Im thinking possibly injector pump may be one of them. Any help would be appreciated. Cheers.

i think thats the one for the ecu. run vis the main ecu relay as well as injection pump.
have a look at the wires on the control valves on the pump, there has been cases of the wiring insulation breaking off and the wires shorting out.
