"...and replaced the intake gasket."

Please, don't worry about very little fuel coming out of the rail until you check some other things. The Fuel Pressure Regulator will not "pull-off" if there is no or extremely low manifold vacuum. That means little or no fuel flow.

Go back a bit. You said that the car was running fine until you changed the intake gasket and fuel filter. My first question is, why did you change the intake gasket?

You also said it "acts like" it is starving for fuel at idle and low speeds, but runs normally at full throttle. Why are concerned about fuel flow at cranking speeds? The car starts and runs, granted poorly, but it runs. It is getting fuel.

The symptoms you describe are classic false air indications. False air is air introduced to the intake after the air metering device. Look for a disconnected or wrongly connected vacuum hose or something along those lines.

Let us know what you find.
