Having problems with your 2005 BMW 3 Series ?

My 2005 325 CI gas guage reads empty but tank is full. I replaced the pump/sensor under the passenger rear seat but still have no reading. The pump/sensor showed signs of an electrical short on the wiring on the pump. The sensor on the drivers side rear looked fine. Fuel pump fuse is fine. Performed a diagnostic test of the on board computer (OBC) to check the sensor performance and received a code 3 meaning implausible unit. Any ideas are appreciated.
