Filter is good. Relay is good. Inertia switch is fine. Factory shop manual says check voltage on pump. If it is aproximately 10 volts then replace it. volatge is at 8.72 volts. A rude mechanic at the Ford garage said that isn't aproximately 10. Anyone know anything on this matter? I also can't hear pump. Does the probe pump make enough noise to hear it? Car was parked running but sat for last 5 years. Any help would be appreciated. Thank you. If I need a now pump, does any one have any recomendations. I see there are a few to choose from off of E-bay.
