WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Use care to prevent combustion from fuel spillage. No smoking, open flames or any kind of arcing. Fuel in fuel system remains under high pressure even when engine is not running. To avoid injury or fire, release fuel pressure from fuel system before disconnecting any fuel line. To avoid unnecessary fuel spillage and fire hazard, any time fuel lines are disconnected, ignition switch must be in OFF position unless fuel pump operation is required for test purposes.
- Remove fuel tank cap. Using Fuel Pressure Gauge (T80L-9974-B), release pressure from system at pressure relief valve (Schrader valve) located on fuel injection manifold rail.
- If fuel pressure gauge is not available, disconnect Inertia Fuel Shutoff (IFS) switch. IFS switch is located behind right kick panel. Remove fuel filler cap to release fuel tank pressure. Crank engine for 15 seconds to release system pressure.
