86 na fuel pump
I have a problem that my fuel pump only comes on in the start position, not the on position. Does anyone know how the fuel pump is wired?

Yes, the above is how the pump stays on while the engine is running.
But when starting (cranking), IIRC, the circuit opening relay gets a start signal and turns on the fuel pump, not the switch inside the AFM.
OP, if you want to check operation of the fuel pump, turn ign. on (warning lights on, engine not running), and jumper the yellow fuel pump check connector in the harness near the AFM (two female pin open ended plug sometimes covered with a black rubber boot).
