Did Lots of Work, Now 300CD Won't Start!?

I started a couple threads a week or so ago about this car. I'd recently purchased it and discovered it had a shop rag wrapped around the cam under the oil fill cap. It was running and starting fine at the time but I decided to tear into it to get as much of the rag cleaned out as I could. While I had it apart I did a bunch of other work and now that it is back together it just cranks and cranks but will not start. I did the following work:

1. Replaced battery

2. Replaced all v-belts

3. Replaced temperature sensor near glow plugs (dash gauge was not working)

4. Dropped oil pan, cleaned out all of the shop rag remnants, replaced the rubber grommet and mesh screen on the oil pickup, replaced oil pan gasket, new oil and oil filter.

5. Set valve adjustments and replaced valve cover gasket.

6. I discovered that the guts of the vacuum pump valve (screws directly into the top of the vacuum pump and connects to the line that goes to the brake booster) were missing. I am still waiting for the replacement valve to arrive, but I reinstalled the bad valve just to try to get the car started. Would this cause the car not to start?

7. New fuel filters (I made sure to fill the primary screw on filter with fuel before installing).

8. Replaced some of the short vacuum line connectors that were obviously bad.

9. General cleanup/flush-out of vacuum lines, banjo bolts, fuel lines, etc.

Again, this car was starting and running fine before I took it off the road to get the rag issue cleaned up. I feel pretty confident that it is getting fuel because several of the injectors are weeping fuel (another issue I need to address) as they were before I did all the work. I also feel fairly confident that the glow plugs are working (I did not pull all of them out, but I checked the resistances of each plug circuit and voltages going to each plug and everything seemed fine).

I have not done a compression test, but again this car was running fine before I did the work.

Any suggestions? Thanks.
