Friends Attak quit on him going across the lake. Fuel pump was not running. Towed it home. Found a mouse nest by the fuel pump and wires chewed. Fixed wires but only got 3 VDC at the connector. Found fuel pump relay was the culprit. Swapped in a parts store relay and now has 12 VDC at the connector but fuel pump won't turn on. Swapped in the relay next to it and has 12 VDC but again no pump. Put 12 VDC to the pump and it works but sounds odd. Any ideas?
