When you are driving down the road power for your in-tank fuel pump is supplied through the oil pressure sending unit. That's at that the front left of the engine and down low of course.
When you turn on the key, power is supplied back to the pump through a relay for 2 seconds. To check for that pump running you have to have somebody back there laying down under the tank as you turn the key on.
When you turn the key to the start position the relay again provides power back to the fuel pump. As oil pressure comes up when the engine starts power is then picked up by the oil pressure sending unit.
That relay is likely located under the dog house over by where your gas pedal is. It is held by a metal clamp.
You may also have a multi wire connector at the top back of the tranny sort of down on the side a little through which that power goes back to the pump.
Good luck.
