Message	Fuel pump relay when put power to terminal 1 and ground terminal 2 clicks. Then used multimeter on diode/ wifi looking setting between 3 and 5 and have a strong solid buzz indicating contact there too. Now its off to the fuel pump or controller being bad. Still wondering if its the pump seeing it ohms out of spec. But why would it work w power supplied to orange wire?/ Maybe time to tear into panel to look at FPCU. ALSO .. why would it not work when bypassed ? Onward i guess
