Have this 450 excavator that am not getting power to the ec motor that controls the fuel. The machine will start manually by moving the throttle cable but not with the ec motor. Seriel is zx450lc I would like to know where the ec motor gets power from? The fuses are all good and the led light is flashing on the two ecm behind seat. The ec motor has a 4 plug wire and a 3 plug wire going to it. The 4 plug has a red, orange,yellow,black wire. At one point I did have power going to this plug.
