Fuel System - General Information: Other Ford Escape II

Fuel Pump (FP) Shut-off Feature

In the event of a moderate to severe collision, the vehicle is equipped with a Fuel Pump (FP) shut-off feature that is initiated by the event notification signal.

The event notification signal is a signal provided by the Restraints Control Module (RCM) to the FP control module. Signal communication between the RCM and the FP control module allows the PCM to shut-off the FP.

Should the vehicle shut off after a collision due to this feature, the vehicle may be restarted by first turning the ignition to the OFF position and then turn the ignition to the ON position. In some instances the vehicle may not start the first time and may take one additional ignition cycle.

Fuel System Pressure Release

1. Remove the FP fuse.
2. Start the engine and allow it to idle until it stalls.
3. After the engine stalls, crank the engine for approximately 5 seconds to make sure the fuel injection supply manifold pressure has been released.
4. Turn the ignition switch to the OFF position.
5. When the fuel system service is complete, install the FP fuse.
6. Start the vehicle and check the fuel system for leaks.

MATERIAL SPECIFICATIONS

Disconnect - Type I

Note. When reusing liquid or vapor tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating from the tube or damage to the tube or connector retaining clip can occur. Apply clean engine oil to the end of the tube before inserting the tube into the connector.

Note. Fuel injection equipment is manufactured to very precise tolerances and fine clearance. It is essential that absolute cleanliness is observed when working with these components or component damage can occur. Always install plugs to any open orifices or tubes.

Note. Do not use any tools. The use of tools may cause a deformity in the clip components which may cause fuel leaks.
