Fuel Pressure Release
WARNING: This page is about a different car, the 1996 Mercury Sable and 1996 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
- Remove fuel cap to release fuel tank pressure. Remove relief valve cap. Relief valve (service port) is located on fuel supply manifold. Using Fuel Pressure Gauge (T80L-9974-B), release fuel pressure from relief valve (Schrader valve).
- If fuel pressure gauge is not available, disconnect electrical connector to IFS switch. For IFS switch location, see the INERTIA FUEL SHUTOFF (IFS) SWITCH LOCATION table under INERTIA FUEL SHUTOFF (IFS) SWITCH. Crank engine for 15 seconds to reduce system pressure.
