Just to follow up, I did get a new injection pump and finally got the car to stay running! Thank you guys so much for your help. It runs pretty good, but not long after I decided to tear some things apart. The engine has a bad clank/clatter and after reading: http://www.peachparts.com/shopforum/diesel-discussion/361611-clank-clank-when-cold-new-engine-time-3.html

i removed the oil pan and thrust bushing. The thrust bushing looks really worn and was very loose. Everything looked good in the pan. I decided then that i was going to rebuild the vacuum pump because oil was starting to leak and I wanted to check the play on the intermediate shaft. Next I was able to strip out the bottom bolt on vacuum pump. (super fun) I got it out with a screw extractor. After that I was pretty excited and pulled the whole pump apart. Now I don't know how it goes back together. Does anybody have a diagram of these older pumps? The hoses are 90 degrees apart.
