Fuel Injection Pump: Removal
WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING:
Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.
WARNING:
Clean all fuel residue from the engine compartment. If not removed, fuel residue may ignite when the engine is returned to operation. Failure to follow this instruction may result in serious personal injury.
WARNING:
Always disconnect the battery ground cable at the battery when working on an evaporative emission (EVAP) system or fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
NOTE:
Do not loosen any fittings or plugs on the fuel injection pump.
- Release the fuel system pressure, refer to FUEL SYSTEM - GENERAL INFORMATION .
-
NOTE: Use care when removing the fuel injection pump noise insulator. Spreading the openings will aid in removing the fuel injection pump noise insulator and reduce the risk of damage.
Remove the fuel injection pump noise insulator shield.
- Disconnect the fuel injection pump electrical connector.
- Disconnect the fuel jumper tube-to-fuel injection pump quick connect coupling, refer to FUEL SYSTEM - GENERAL INFORMATION
.
-
NOTE: To release the fuel pressure in the high pressure fuel tube, wrap the flare nut with a shop towel to absorb any residual fuel pressure during the loosening of the flare nut.NOTE: When only disconnecting the high pressure fuel tube at the fuel injection pump flare nut, the high pressure fuel tube can be reused.
Remove the high pressure fuel tube bracket nut and discard. Disconnect the high pressure fuel tube-to-fuel injection pump flare nut.
- Alternately loosen the 2 fuel injection pump bolts one complete revolution at a time.
- Remove the fuel injection pump O-ring seal and discard.
- Remove the fuel injection pump roller tappet.
- Inspect the fuel injection pump roller tappet, refer to FUEL INJECTION PUMP ROLLER TAPPET INSPECTION .
