I've been playing with the fuel pressure sensor today as the P0089 code has returned. It's the third time in the last few years. I've found that running neat fuel cleaner through the fuel rail seems to work.
However, access is via the fuel pressure sensor in the line. There's a Schrader valve adjacent to the sensor. I released the fuel pressure via the valve. Pressed it several times and there is no pressure and no release of any more fuel. But when I take the sensor out, fuel sprays everywhere. I'm puzzled.
