Bad check valve in your pump...

is allowing the fuel distributor to vapor loc(long one!) into the mixture adjustment hole on the fuel distrib. When you have engaged the hex-bit adjuster inside, cock the allen wrench to one side and you will be able to lift the plate. If the system has been pressurized by recent cranking, you'll hear a brief whine as the injectors spray until the residual pressure falls below the injector opening pressure. This clears bubbles that have formed in the fuel distrib. Once they form, the upifting force on the plate from the modest airflow at cranking can't overcome the control pressure holding the plunger down.
If this works, replace the check valve on the pump. I started my 75 EMS like this for years before figuring out the culprit. I used to jump the pump relay so the pump was running when I lifted the plate. You can easily hear when fuel flows again.
