hello there,


I would not worry about the fuel sender, just make sure that the power is on the green/orange wire and the the black is good ground.

i checked, there is no green/orange wire at the pump. i have 5 wires, and the only one with power is white with black strip

That is the wire that feeds the fuel pump motor, I would say you need a new one if not pumping. Check that brown/yellow is grounding.


I am sorry I forgot this has a separate fuel pump driver module In rear, behind trim panel, LH side / behind luggage compartment lining, LH side, this is where the gn.or wire is at.
