I am sorry to hear about your husband! to remove the fan belt is an easy and fast operation for any local shop and it should not cost very much to ask a local mechanic to remove the belt for you and verify that you do not have a bad pulley bearing, I would hate to see a pulley completely stop turning while you are driving as this could cause a belt to come off and potentially leave you stranded, The clerk at the auto parts store may even be able to take a listen to the pulleys and detect if the noise is coming from this area! While you are there, ask them if their scan tool has the ability to see what the electronic fuel pressure sensor is reading, some non-ford scan tools have this ability! The pressure should not drop less than 35 psi, nor go greater than 70 psi
Did you get this problem corrected?
