I suspect the VRO fuel pump is bad. Coming from the pump is a harness with Blue / Brown / Black wires.
With the 3 wire plug disconnected..... On the engine side of that plug I get voltage to the blue wire during starting. If I apply 12V to the pump side of the blue wire no pumping action. The black wire is grounded. The brown wire goes to the oil tank.
Is the pump bad? Or is there another test to perform? The replacement is $365.00
Thanks
