How/Where do I check the Fuel Pressure on my 95 Aurora?

How much fuel pressure is needed to start and then for the engine to run normally?

Figured it out on my own, there is a port on the fuel injector rail.
Pressure should be above 40-45 psi to start.

Turns out fuel pump is okay,I have enough pressure.
The sending unit is not working correctly, it showed I had 1/4 tank, but it was bone dry.

Have to have fuel to generate pressure :rofl:
