Hello all. I’ll try to describe this the best I can, with my limited understanding.
This is a 2003 XKR SC 4.2 Convertible
In the photo below, what’s depicted is the fueling system from the 2003 electrical guide, specifically referring to the Fuel Pump Module or Fuel Pump Pressure Control Module and Fuel Pump. The module is located on the “C” pilar on the RH side. Bottom corner of the fuel tank… It’s working.
From the schematic, it seems to show that there are two outputs supplying voltage to both terminals of the fuel pump with no ground. As of now, the fuel pump is inoperable.
What is to be understood from this? How is the appliance grounded and what is the path of ground, control or variable operation of the pump?
I am not blowing fuses. The FPM is the relay. There is no relay. The pump is connected but not spinning and WILL spin on a +/- connection at bench test. With test light, reading voltage at both the YR and R wires at all connectors right up to the pump at the SAME time.
I am completely stumped and open to all and any advise, direction, suggestion and any questions if I can be of any use to add additional info or clarify.
