Thank you for the quick responses. Sounds like a few others have done the same. This morning, I applied a vacuum to the return line without much result. I was using a brake bleeder tank, so maybe it did not pull much vacuum. Anyway, I then tried starting the car with the vac applied and finally saw some liquid in the line. Since it still did not start, I then cracked the nuts on the injectors, one at a time and cranked the starter each time until I saw liquid. After getting all four bled, I attempted another start. Yes! It worked!!!! I then checked my injection timing and found it to be within range and slightly advanced, where I like to keep it. Finally, I can clear my bay and get on to another car.
