Fuel System - General Information: Other Ford Explorer V

FP Shut-off Feature

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

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 turning the ignition to the ON position. In some instances the vehicle may not start the first time and may take one additional ignition cycle.

General Procedure

1. NOTE: The FP relay is located in the BJB, location F15. Remove the FP relay.
2. NOTE: The engine will crank and not start. Crank the engine for approximately 20 seconds.
3. Crank the engine an additional 20 seconds to make sure the fuel system pressure has been released.
4. Turn the ignition switch to the OFF position.
5. When fuel system service is complete, install the FP relay.
6. NOTE: It may take more than one key cycle to pressurize the fuel system. Cycle the ignition key and wait 3 seconds to pressurize the fuel system. Check for leaks prior to starting the engine.
7. Start the vehicle and check the fuel system for leaks.

Disconnect - Type 1

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.

Note. Fuel injection equipment is manufactured to very precise tolerances and fine clearances. 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.
