Hello, Again, Stevieray1 is likely correct. There is a shut-off switch for the fuel pump behind the kick panel, and the button must be pushed down (you would feel it click) in order for the fuel system to receive operating voltage. Look at pics online for the location. It has a big red button right on top.
