Fuel Pump; 3 wires, which ones for sensor (meter) and which for the pump?

hey well today my car didnt start, its trying to start but wont, i got out my spark tester, get spark in every plug, so its not the ignitor or the coil or the dizzy. Start thinking its the fuel pump, take out my back seat (coupe) and open up the access hole (3 philiphs screws) i see wires running to it. First i listen for the fuel pump, its supposed to make noises when you turn the ignition to "ON" nothing. So i unplug the plug with 3 wires running to it, one is thick yellow with silver marking, which runs somewhere farther down where i cant see. There there is a green/brown and a yellow/white wire which both run to the top of the fuel tank, i belive this is the fuel guage meter? Now i check for voltage, i get 11.5 and 6.5 on the wires running to the top, and i get 0 to the wire running farther down.

I belive my fuel pump is not getting any power, i heard this is caused by the main relay, however i re-soldered it just 6 months ago or so, and drilled a lot of holes for ventalation, and the car is in a garage at about 4 degrees celcius, which is pretty damn cold. Before my car wouldnt start but the "S" light (sports button on auto) would flash, i would wait 5 mins and car will start, now it dont start at all, so is it still most likely the main relay?

Thank you!

Me thinks you're at the fuel level sending unit access cover. Fuel pump should be on the other side of the tank, which I hear is only accessible by dropping the tank.diagram

But you can bypass the main relay and check for power to the pump. Should be in a stickie.

ya i am at the "fuel level sending unit access cover" is this not where the power goes to the fuel pump too tho? like i said i see a wire running farther down along the fuel tank, and this wire has no power.....
