Does anyone know why the Fuel Pump Relay in my 2000 Explorer 5.0L quit working? All power seems correct according to FCS-12206-99 Diagram 25-1 except circuit 238 DG/YE never becomes hot. I've tried a few different relays and cleaned all connections.
In ACC/Run, the trigger (Pin 2/86, circuit 926, LB/OR) is hot and off otherwise. Pin 1 (Circuit 361 RD) and Pin 3 (Circuit 1059 LB/OG) are also hot as indicated in the diagram.
I think Pin 1/85 is normally ground for such a relay, but the diagram shows it 12v here. That seems to mean there is no ground for the relay, so how could it ever be activated and send power out Pin 5/87 when trigger is on?
