If it smokes it is getting some fuel. I have seen mufflers plug up where car will not get enough air to run. Also check air filter.
For a diesel you need fuel, air, compression, and sequence to start. You are missing one. I have seen diesels flood before where they get so much fuel in the cylinders that they will not generate the heat needed to start. I have disconnected start and hooked up to 24V to get car to start, when you can not pull start them. Note the 24V trick also works if engine sat for long time and rings are stuck, then engine running usually fixes the stuck rings and all is well again. The trick is to put 24V to starter only and not to whole electrical system which will fry things.

I had a new set so I put them all in but it did not help at all. I am starting to wonder if I have run it low on fuel. I knew I was getting toward the bottom of that tank given the mileage on the trip odometer etc but was waiting for the low fuel light to come on before refilling. I have about 350 miles on the tank according to the trip odometer. I have gone further than that but only in warmer weather with all highway driving. This tank is while it is cooler and has some urban driving so I may not have much left in th tank. I am wondering now if that light may have malfunctioned. So, before I dig any further, I am going to pick up a 5 gallon can of diesel and pour it into the tank. I might even change out the fuel filter as I have never done that in my 4 summers of driving it. I also got some of the small clear filters but the car did not have one originally and I have never put one in so I cannot crawl under and look for fuel or for crud in the filter either. My initial thought was the glow system as I drove the car on Saturday and it ran like normal. I went to help my brother-in-law do some electrical work and install a roof vent in his new garage. That is about 45 minutes away. I drove out there on Saturday morning and the car sat on the street from 10:30 to about 8:00 PM and then started normally and drove fine for 45 minutes home in the dark. Maybe I am lucky that I made it into the garage. I did not use it at all on Sunday and then Monday morning, it would not start. It cranks and it tries to fire and it smokes a cloud out the back but it does not start. Will add some fuel and see if that resolves the problem. My recollection is that it may take a fair amount of cranking if there is now some air in the lines.
