Turning the key to pos II runs the pump for a couple of seconds to build up pressure. Your needle should go from 0 to 30+ lbs right away. If it takes a couple of turns of the key to get pressure, then the gasoline in the line is flowing back to the tank when the engine is off.

There is a preventer valve between the filter and pump that needs to be replaced. Jumping the relay enables the pump to run continously with the key in pos II or III.

Feel good about this, newer Volvos have the valve as part of the fuel pump. When the valve fails, the pump gets replaced!
