Fuel sent through the fuel rail to the injectors that is unused returns to the tank under low pressure. In your Brick it likely spills from a metal pipe at the ceiling of the tank into the tank's fuel supply. It's possible that is the agitation you're seeing. Regardless, you must verify that all interior tank hoses are in good condition, that they attached firmly by fuel injection hose clamps to the pump and the fuel filter, and that the fuel filter isn't plugged. If you don't know the age of the fuel filter, replace it. The NAPA 3032 filter seems to perform satisfactorily for many forum members. I use the Mahle KL145.
After a few attempts at starting, remove the plugs and let us know it they're wet or dry.
