Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. The problem you are describing is most likely caused by a failing selector valve located on the frame rail just in front of the front tank providing both fuel pumps are running when selected. Start first with making sure both pumps run when you place the switch on them. This should not have anything to do with having the tires replaced.
