How I read the wiring diagram is I have keyed power at C6 which turns off and on with the key. The blue and orange wire had power coming out of C6. It never get to the blue and orange wire on the plug for the fuel pump.

According to the EWD for a 2000 5VZ, the fuel pump relay (called “circuit opening relay”) is only closed when the starter is running and when engine is running. It is controlled by the ecm. The ecm needs to see starter engagement (also ecm controlled) and engine rpm indicating the starter is engaged and rotating the engine. Like I said earlier, the fuel pump only runs while starting or engine is running.
EDIT: This is how the fuel pump operates for all 3rd gen 4Runners with gasoline engines.
