also it happens more on bummpy gravel roads then it does on the highway.
from the guys that have set this code was it the HPFP pump or the rail sensor? Price for the fix so i know what to expect and dont get screwed?
and is there a better pump to change it out with or am i stuck with the same pump and in another 75k possibly changing it again
thanks and sorry for the multiple Q's
Ford has a TSB flash to address this issue. Prior to lasted TSB flash Ford would replace the HPFP with a rev B updated HPFP.
First step would be to make sure the latest TSB is installed.
My HPFP was replaced at 131K with a rev "B" pump. Now at 176K and no problems
