no compression

hi all. i have a 2005 f350 6.0 it started running rough and smoking. I had a family friend who used to be a diesel mechanic come over and plug in some diagnostic tool to the truck and it showed no compression on number 2 cylinder. Any idea what would be the cause of something like that ?

Your tech friend probably meant low "contribution" from cylinder #2 if all he did was plug it in to a diagnostic tool.
