Fuel pressure for that vehicle should be between 60-66 psi, if you have 55 it isnt enough. At that mileage thefuel pump is most likely the issue, usuall they go out way before that. As far as the white smoke goes, itis most likely a head gasket or a small crack in the head itself (thin wall castings). The intakes will leak the coolant into the oil via the lifter galley under the manifold.
