I took your advice Fishfiles and addressed the fuel system. I replaced everything from the pickup tube to the fuel pump. It then would only start when the weather was warm. So then I took Tazza's advice on looking into the glow plugs . There is an old thread in which he explains how to replace the plugs.I decided rather than test,I would just go ahead and replace ( the old ones had been in there for 20 years). It was not that difficult,just as he had said - It just took a while. And now......It starts like a champ!!!!!!

New glow plugs work wonders. Replaced mine a couple of years ago and it starts in +10 F weather now without a problem.
