Removal
NOTICE: Do not loosen the fittings or plugs on the high-pressure fuel pump.
- Relieve the fuel system pressure.
Refer to: Fuel System Pressure Relief (310-00B Fuel System – General Information) – 1.6 L EcoBoost (132 kW/180 L hp) – Sigma, General Procedures). - Disconnect the battery.
Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures). - Remove the ignition coil from the spark plugs.
Refer to: Ignition Coil-On-Plug (303-07B Engine Ignition System - 1.6 L EcoBoost (132 kW/180 L PS) - Sigma, Removal and Installation). - Remove the air cleaner outlet tube.
Refer to: Air Cleaner Outlet Tube (303-12B Intake Air Distribution and Filtration – 1.6 L EcoBoost (132 kW/180 L hp) – Sigma, Removal and Installation). - Quickly disconnect the positive crankcase ventilation (PCV) tube. Release the quick-release coupling. Release the hose retainer, loosen the clamp, and then remove the PCV tube.
Refer to: Quick-Release Coupling (310-00B Fuel System - General Information. Information - 1.6 L EcoBoost (132 kW/180 L PS) - Sigma, General Procedures).
- Remove the TC inlet tube nut and stud, and loosen the TC air inlet tube clamp, then remove the TC inlet tube.

- Quickly disconnect the positive crankcase ventilation (PCV) tube. Release the quick-release coupling. Release the hose retainer, loosen the clamp, and then remove the PCV tube.
- Remove the high-pressure fuel pump heat shield.

- Release the wiring harness retainers. Disconnect the FRP sensor electrical connector, the high-pressure fuel pump electrical connector, and the CMP electrical connector. Set the wiring harness aside.
- Remove the ignition coil-on-plug mounting bracket lock nut. Loosen the captive remaining ignition coil-on-plug mounting bracket retainers, then remove the ignition coil-on-plug mounting bracket.

- Remove the ignition coil-on-plug mounting bracket insulator.

- Disconnect the fuel supply tube from the high-pressure fuel pump.
Refer to: Spring-Lock Couplings (310-00B Fuel System - General Information. Information - 1.6 L EcoBoost (132 kW/180 L PS) - Sigma, General Procedures).
- Remove the high-pressure fuel pump fuel supply tube stud.
- Disconnect the high-pressure fuel pump fuel supply tube flare nut. Remove and discard the high-pressure fuel pump fuel supply tube.

- Disconnect the fuel supply tube from the high-pressure fuel pump.
NOTICE: To relieve the fuel pressure in the high-pressure fuel system, wrap a shop towel around the high-pressure fuel pump fuel tube flare nut to absorb any residual fuel pressure while loosening the high-pressure fuel pump fuel tube flare nut.
Disconnect the high-pressure fuel tube flare nuts. Remove and discard the high-pressure fuel tube.
- Remove the high-pressure fuel pump mounting bolts, then remove the high-pressure fuel pump.

- Remove and discard the high-pressure fuel pump O-ring.

- Remove the high-pressure fuel pump drive tappet.

- Inspect the high-pressure fuel pump drive tappet. If any spots or scoring are found, especially in the indicated areas, inspect the high-pressure fuel pump and the high-pressure fuel pump drive tappet cam lobe. Install new components as necessary.

Installation
- Remove the retainers and the cover.

NOTICE: Rotate the crankshaft clockwise (CW) only, otherwise engine damage may occur.
Rotate the camshaft until the high-pressure fuel pump cam lobe is at TDC.
- Lubricate the high-pressure fuel pump drive tappet and the high-pressure fuel pump drive assembly bore with clean engine oil.
Material: Engine oil - SAE 5W-20 - synthetic engine oil / XO-5W20-Q1SP (WSS-M2C945-B1)
- Install the high-pressure fuel pump and loosely install the high-pressure fuel pump bolts. Alternately tighten each bolt one-half turn at a time until seated. Tighten the high-pressure fuel pump bolts.
