We have one of the older (1984) military 1 1/4 ton diesel pickup trucks at 
work. When we first got it we had the same problem and it turned out to be the 
glow plugs. There is one for each cylinder sticking out of the block. They are 
fairly easy to change but be aware that the military vehicles use a different 
glow plug than the civilian trucks. You can tell the diffence by the size of 
the blade for the electrical connector. If you check the plugs and they are not 
the problem try checking the glow plug solenoid. I'm told they sometimes go 
bad.

Good luck,
Karl

<< I have a 98 GMC one ton dump truck with a General Motors diesel
 engine in it. I have not noticed any changes in fuel economy or anything
 but it has all of a sudden become hard to start. The last couple days
 when the temperature was around 30 degrees, which should not be a problem,
 it would barely fire and would run on only one or two cylinders and blows
 clouds of smoke until all cylinders are firing. Once running, it starts
 and runs normally for the rest of the day. This engine is not a Duramax
 diesel engine but was made a year before they made the switch.
 
    If this were my JD crawler with the diesel engine, I would suspect
 that several glow plugs were bad but as I have not been able to find a
 manual for this engine, I have no idea if it has glow plugs or not or
 where to look. The dash has a "Wait to Start" light which works normally
 so something is pre-heating - or is supposed to.
 
    It has a block heater but I can't see keeping it plugged in when
 the temperature is only 30 degrees.
 
    If you have any actual experience with this engine, I would
 appreciate hearing from you, on or off List.
