Fuel System Pressure Release
WARNING: This page is about a different car, the 1998 Lincoln Mark VIII. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Always relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
- Remove fuel filler cap to release fuel tank pressure. Remove relief valve cap. Relief valve 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 INERTIA FUEL SHUTOFF (IFS) SWITCH LOCATION table. Crank engine for 15 seconds to reduce system pressure. Turn ignition off. Reconnect IFS switch connector.
