I just completed the following:
-ran clear hose from T-Valve. Fuel ran into container with no air bubbles present. I closed the valve and opened the air valve on top of the filter and fuel spurted out.
-changed PMD with my spare. #5 resistor is in place.
-searched for optical filter and I do not see one.
Drove it a short distance and ran fine. I am going to hold off on changing the new Rock Auto HB and pulley I received until I make sure this code is not coming back. I will drive it for a few days and see if code returns.
