Engine Mechanical problem
2005 Ford F250 V8 Four Wheel Drive Automatic 115000 miles
I have a 2005 Ford F250 6.0L diesel. It has developed a hard start condition. When cold it will turn over as normal. It will fire once at about the same number of revolutions as it always did. If you continue cranking it may or may not start. If it starts it will buck and skip for a few seconds and then somewhat smooth out. I replaced the glow plug module. Stilll starts the same. If I plug it in, it will start as normal. The code P0611 keeps coming back after I clear it.
