Injection Control Pressure Leak Test: Notes
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Ford RV Cutaway, 2002 Ford Pickup, 2002 Ford F550 Super Duty, 2002 Ford F450 Super Duty, and 2002 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
Removing Injection Control Pressure (ICP) sensor and inspecting level in oil rail will determine if oil is being supplied to rail. Removing inspection plug in top of reservoir will help determine if reservoir is full. See Figure. A reservoir that drains back after engine has not been operated for a long period of time can cause a hard start condition. If reservoir empties after filling, ensure it is being supplied oil from low pressure oiling system.
