Recommended Procedure
WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Fuel pump will only run for 20 seconds.
- Turn ignition on. Open the drain on the Horizontal Fuel Conditioning Module (HFCM), fill a clear container until it is half full. Close the drain and turn off the key.
- Observe WATER IN FUEL light while cranking. If the indicator is illuminated the fuel is probably contaminated with water.
- Flow out of the drain should be a steady stream. Insufficient flow could indicate fuel supply or fuel system problems.
- Inspect fuel in the container. It should be clear not cloudy. It also should be free of water and contaminants. Dyed Red or Blue fuel indicates off-highway fuel.
- Some sediment and water may be present in the fuel sample if the fuel filter has not been serviced for a prolonged period of time and/or if the sediment and water have not been drained recently. If that is the case a second sample may be required to determine fuel quality.
