HI... just joined Hybrid Z and have been looking through the forums. I am having the same problem with a 76 280z. It was running and then the next morning would not start. Have checked about everything. I think it might be a timing issue - that's tomorrow's task! What did you do about your fuel pump? If you disconnect the solenoid at the starter so you can turn the key to start (without turning over the engine), you should be able to hear the pump running. Also, with the key in the on position, if you manually move the flap in the AFM you will also hear it run. You can also use a screwdriver against the fuel regulator to hear it "humming" as you hold the flap.. If you did change the fuel pump, what did you use and how is it working out? I might change mine too. thanks.
