F250 6.0 HARD START

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.

Hi, one of the injectors has shorted not allowing the module to work properly, uses an ohm meter to test the injectors, replace the one that has failed, note special tools are required for this job.
