The fuel pump supply wire runs down the offside of the car along the sill inside the car, under the trim bits by seals, along with the lights wires, then at back of car they dive down and then go forwards towards the pump and float assembly(tank) until they split into each bit ie tank and pump.
I would first check the fuel cut off, under the spare wheel, if the white button has popped up it has tripped out, so just press to reset.
