Sounds as if the transfer pump between the tank and injection pump is the issue. A restricted line from the tank would stop the strongest pumps from doing the job. Fuel filters are suspect too.
this is a job best left to the diesel experts. While you may be able to get it off the engine the settings are critical for engine life. If you get them wrong you will burn holes in the pistons or over rev the engine causing destruction. Diesel pump calibration is done on a bench and each plunger is set to produce the right amount of fuel and the governor is set to cut the fuel at a predetermined rpm setting ( flight idle)

I'm guessing you have fixed this or given up after 13.5 years, but here is my suggestion for the next person who has this trouble. If you ran it out of fuel and left it over the winter, it could have a drop of fuel that hardened and plugged one of the fuel ports in the carburetor. I have had this happen and needed to remove the fuel bowl and poke the dried film with a pin. Put it back together and it started right up.
Do not know what brand that is, but you can find choke cables at lowes, amazon .com. or any number of small engine repair shops depending on where you live. An after market cable could be easier to find and work just as well.
