Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello Rick and thank you for your question,The most common cause for these two codes to set in most cases due to either a failing FPDM or the fuel pump and since you have replaced the module then I would suspect the problem with the fuel pump. If its running continuously its likely because the pressure is not right and the fuel is foaming from a failing pump. Before you replace anything else run through the steps in the link below to recheck the FPDM and the circuit to it and the pump.https://dl.dropboxusercontent.com/u/104923897/Fuel%20pump%20trest%20Jul%2020.pdf
Usually due yo a false reading from a foaming fuel pump or the FPDM is defective. I would run the steps and see what you find. I suspect the pump is failing.
I think you can if the sensor is sending the wrong reading. Spend a bit of time and run the steps I sent you and see if it will help you narrow this down.
