Check your MAP sensor. My 92 f150 had a similar problem, wound up being a bad MAP sensor.

Remove the fuel filter and pour the fuel into a glass container, note the color. Wipe off the ends of the filter, and blow through it the direction the fuel flows. There should be nearly no restriction at all. If there is, replace it. Also check with a flashlight all along the fuellines from the tank to the engine for aftermarket filters that someone may have installed. The fact that there is pressure at the manifold shows pressure, not volume. A clogged filter can let through pressure, not volume, although I wouldn't rule out the pump completely.
