P0230 Incorrect voltage on the control circuit of the fuel pump relay.

Just collapsing the fuel pump relay can also set this code. There is only 2 possible causes, the relay ground side is open. or the power side which is from the ECM. It is either open or a fault with the ECM.

On one side of the relay is the ECM control, with key on it should be battery voltage, on the other you should have ground, what the ECM detects is no power to the fuel pump relay from the ECM, check the power side of the fuel pump relay
