Hey... while waiting on my order from Nissan for a new Fuel Pump Relay Switch, I looked up how to test the realy fuses and was able to determine the fuse WAS NOT bad..even double confirmed by testing other fuses (lol, wasted more money again!)...So, within the relay switch connection you have 4 wires (#3 & #2 are going to the battery, #5 going to the FPCU, #2 going to the ECU...I think I have this correct based of the wiring diagram & test)....well I connected the Fuel Pump Relay Fuse...then as you can see in the picture below, I went from the back of the wire harness it plugs into and stuck a wire that I grounded to my car (Blue wire by my thumb) to the #2 spot and sure enough, the Relay Switch made the clicking sound and my Fuel Pump started running!...but I still can get the car to start!...Do you think that my ECU went bad?...which I'm guessing could be possible considering my mechanic was around the ECU when he replaced my Evaporator Box doing A/C work (also, the drain hose was disconnected causing water from the A/C to drip right in the area where the ECU use!...but could it really have shorted just one part?)
