WARNING: This page is about a different car, the 2008 Dodge Magnum, 2008 Dodge Charger, and 2008 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
The fuel system is under constant pressure even with engine off. Before servicing fuel rail, fuel system pressure must be released.
- Disconnect electrical connectors at all 8 fuel injectors. Push red colored slider away from injector (1). See Fig 1. While pushing slider, depress tab (2) and remove connector (3) from injector. The factory fuel injection wiring harness is numerically tagged (INJ 1, INJ 2, etc.) for injector position identification. If harness is not tagged, note wiring location before removal.
- Disconnect electrical connectors at all throttle body sensors.
- Remove four fuel rail mounting bolts (1) and holddown clamps. See Fig 2.
- Gently rock and pull left side of fuel rail until fuel injectors just start to clear machined holes in intake manifold. Gently rock and pull right side of rail until injectors just start to clear intake manifold head holes. Repeat this procedure (left/right) until all injectors have cleared machined holes.
- Remove fuel rail (with injectors attached) from engine.
- If fuel injectors are to be removed, see REMOVAL .
