Low fuel pressure may be easily resolved - Bend Bulletin
-- returnText2 = Q: I have a 2005 Ford F-150 with a 5. 4-liter V-8 engine with slightly more than 97,000 miles. The check engine light hasn’t come on, but a gauge did indicate low fuel pressure. Do you know of any Ford recalls that address this problem. Your pickup employs a no-return fuel system that is unlike the return-based system used on most vehicles prior to 2000. The fuel pump on earlier vehicles sent more fuel to the engine than was needed. This continual looping of fuel kept the fuel rail and injectors cool but returned some engine heat to the fuel tank. Ever tightening emissions regulations prodded carmakers to move toward no-return systems, which reduce fuel tank vapors. Instead of a mechanical fuel pressure regulator, Ford employs a fuel pressure sensor and a fuel pump driver module, the latter of which varies voltage to the fuel pump, keeping pressure just right. Typical causes for low fuel pressure include a dirty fuel filter, weak pump, incorrect fuel tank venting, restricted fuel lines, a clogged pump inlet strainer and faulty electrical control. The fuel pump driver module on Ford trucks of this vintage is known for corrosion-caused failures. The part is attached to a steel cross-member under the truck bed, near the spare tire.
