water in fuel / light
I own a ford F250 SD :Power/stroke diesel. I recently noticed a light indicating I had moister in the fuel. I had both filters changed and drained as suggested in the manual. That didn't fix the problem the light still continues to come on after driving a few blocks or sometimes even goes a few miles before it comes on. One day it never came on at all?
Now it comes on daily. whenever I shut the engine off and restart it's the same story each time.
A friend said he knew someone who owned a truck same year as mine and that Ford Motor Co. sent out a msg about the problem and a certain part purchased from ford would be necessary to fix the problem.
Any ideas? Thanks. Mike

keep draining to be sure it is not water or kiss your injectors goodbye. Hopefully it is a faulty sensor in the fuel conditioning module.
If still under warranty go to the dealer and ask about any TSB's that may affect your problem.

TSB 06-22-12: WATER-IN-FUEL (WIF) LAMP ON / FLICKERING
ISSUE:
Some 2003-2005 F-Super Duty vehicles built prior to 9/22/2004, 2003-2005 Excursion vehicles built prior to 1/10/2005, and 2004-2005 E-Series vehicles built prior to 9/16/2004 and equipped with a 6.0L diesel engine, may exhibit an intermittent / flickering water in fuel (WIF) lamp. The intermittent condition may be more prominent while turning corners, braking, or during uphill/downhill driving.
Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit a continuous WIF lamp on, even without the presence of water, due to debris in the reservoir or corrosion on the WIF sensor pins located in the manifold.
Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit both intermittent / flickering and continuous WIF due to corrosion and the lack of new calibration.
PM me if you want the TSB instructions for cleaning the sensor and the HFCM water reservoir housing.

The intermittent condition may be more prominent while turning corners, braking, or during uphill/downhill driving.
Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit a continuous WIF lamp on, even without the presence of water, due to debris in the reservoir or corrosion on the WIF sensor pins located in the manifold.
Some 2003-2007 F-Super Duty and 2003-2005 Excursion vehicles may exhibit both intermittent / flickering and continuous WIF due to corrosion and the lack of new calibration.
- For intermittent / flickering WIF lamp condition reprogram the powertrain control module (PCM) to the latest calibration using the IDS release B32.11 or higher. Calibration files may also be obtained at MOTORCRAFT PARTS FOR FORD, LINCOLN OR MERCURY VEHICLES.
- If the WIF lamp continuously illuminates without the presence of water, this may be due to corrosion on the sensor pins or sediment build up in the water reservoir.
- Drain the horizontal fuel conditioning module (HFCM) reservoir and look for significant corrosion debris or sediment in the fluid drained from the reservoir. Remove the WIF sensor and inspect for corrosion on the pins. Remove the WIF Senor by first disconnecting the electrical connector, then using channel locks, rotate the WIF sensor at least 45 degrees counterclockwise. If there is corrosion / sediment on the pins, proceed to Step b. If there is not, refer to PC/ED lead diagnostics and do not proceed with the TSB.
- If corrosion on the pins is causing the WIF lamp to illuminate, replace the WIF sensor with service kit, following the WIF sensor installation instructions in the kit.
- If there was significant corrosion debris or sediment drained from the reservoir, clean the housing of the HFCM of any debris following the HFCM cleaning procedure. It is not necessary to replace the Manifold or HFCM assembly.
- Vehicles with both an intermittent and continuous WIF light due to corrosion are to follow actions 1 and 2 as described above, referring to the vehicle built dates and application.
PM me if you want the TSB instructions for cleaning the sensor and the HFCM water reservoir housing.
