OK, the car use two pumps, mostly alternating, sometimes together. 1/ The fuses (2) and the relays (2) are located in the box under the trim (left side) in front of the windscreen, check the fuses and relays. 2/ Under the car, left side in front of the rear wheel well, you will find a connector with the fuel pumps wiring (wiring enters the car approx. under the left rear seat), check the connector for proper contact and the wiring for heat damage. 3/ The fuel pumps are located under the rear seats left and right, remove the covers, remove the connectors and apply 12V directly on the pump left ( both largest in diameter wires ) You can hear the pump running now, if they don't, replace. Do the same with the pump right. My bet is pump right faulty.
