After a no start situation I measured the battery voltage and it was 12.4v. Load tested the batt. and it was OK. Tested the alt. output when running with all elec. equipment on, result was 14v. It appears the batt. and alt. are healthy. Glow plugs are new and all get 12v. I'm beginning to suspect the starter or a bad ground. Wouldn't a bad starter be a problem when hot?
Temp. around 25*F. Rotella 15-40. Battery terminal connections clean and tight. Warm starts are effortless. If the motor is cold, no block heater and not run in several hours = no start. Only one or two revolutions. Jumping helps this situation.
Any input is appreciated.

When was the last time the valves were adjusted? I'm not familiar with your motor so please excuse me if you have hydrolic lifters. Also, is that a synthetic oil that you are using? Perhaps the if it is dino oil then it is hard to start because the oil is making the engine hard to crank. I would think it could be one of these problems along with a bad connection somewhere.
My 116 just gave me similiar problems and I had to twist the possitive connection on the battery then it started right up. It was wierd to me how it cranked once then stopped like happenned to you. Try twisting the possitive cable on the battery then tightening it down.
