The in tank pump on a FL2 is only used to transfer the fuel across the two sections of the tank - it does not supply fuel to the engine.

The low pressure pump is a mechanical pump on the rear of the high pressure pump.

That fault code is set when the car thinks it is low on fuel in the tank and stops the engine running to prevent having to manually bleed the system in case of running out of fuel.

What was the fuel gauge showing when the issue happened?

There’s an issue with the fuel senders which don’t register the correct amount of fuel and the issue is with the wiring in the tank.

Other thing to check is the in tank transfer pump is working as you may have fuel the one side of the tank and not the other

Easiest way to check is to see what fuel is in each side of the tank - should be equal each side
