Question about 2006 Ford F-250 Super Duty
It starts ok in the morning but gets harder to start as the day go's on
The High pressure oil pump is going out.. This is the oil pump that operates your injectors .. when the oil gets hot this oil pump puts out less pressure and will not let the injectors operate right . when the oil is cold in the morning it will have more oil pressure because of the oil stiffness. later after ran a while and it gets warm it wont operate your injectors.. you can also change the oil to a heavier oil but this will only temp fix it.. .. good luck and this is what is wrong with it .. not sure what these cost but they are located at the rear of the engine on top .. on the 6.0 if i remember right not inside the engine.
