Note the diagram. Did you check fuel pump relay wiring circuits? In the diagram, the load side of relay is the right side. See terminal 30, fuse protected and hot all the time. You can use a test light to check for voltage. If hot, use a jumper wire between terminal 30 and 87, in the diagram, the pump should run. If it does, the problem should be on control side of relay, left side in diagram. The top wire on that side in diagram is voltage, goes hot with key on and fuse protected, the bottom wire on that side is ground, controlled by computer.
