Pumping the Hand Primer only bleeds the Air out of the Fuel Supply System (which includes the Fuel Injection Pump Housing and the Fuel Pressure Relief/Overflow Valve).

However, if Air is trapped inside of the Fuel Injection (steel) Fuel Injection Lines (tubes) and the Injectors because Air compresses it moves very little and the Starter cranking needed to get the Air out is hard on the Starter and Better.

To allow the Air a way escape you need to loosen the Fuel Injection Line Nuts at the Injectors and crank the Engine till Fuel is coming out and then tighten up the Line Nuts.

If you loosen the outlet line at the Fuel Supply/Lift Pump when you crank the Engine does Fuel come out?

In order to install a Fuel Pressure Gauge even for a temp test you need to fabricate some fittings and even with a liquid filled Gauge the needle bounces around considerably.
There is few ways to keep that from happenig but you need to read up on it.
