If that has happened, it would be the first that I have heard of it. The best bet would be the two fuel filters. There is a clear one going into the IP, and a metal one that looks like an oil filter somewhere near the front (silver in color typically). For any used diesel purchase, it is recommended to replace these for exactly this reason. Also, check the valve adjustments when you get a chance. You might want to check the air filter and put in some diesel fuel system cleaner and replace any hoses that appear to be dry or cracking.
To see if your really are not getting fuel (don't count on smell), you can loosen a line fitting at the injector and watch it while somebody cranks the engine a couple of times.
