Fuel Injectors: Notes
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:
Smoking or open flame of any type must not be present when working near fuel or fuel vapor. Fuel in the fuel system remains under high pressure even when the engine is not running. Before repairing or disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved to prevent accidental spraying of fuel, causing personal injury or a fire hazard. See FUEL SYSTEM PRESSURE RELEASE . Clean all fuel residue from engine compartment. Failure to do so can cause personal injury or damage to the vehicle.
CAUTION:
Do not attempt to put battery voltage to the fuel injector or damage to the fuel injector will occur. To prevent engine damage, do not use air tools to remove the fuel injectors. The clip that extracts the injector can dislodge and fall into the oil drain hole.
NOTE:
Quick Release Coupling Disconnect Tool (303-755) and High Pressure Line Disconnect Tool (303-625) are required to perform this procedure. See Figure and Figure
.
If removing right side fuel injectors, it may be necessary to remove evaporator case. See appropriate AUTOMATIC or MANUAL AIR CONDITIONING article in HVAC.
