A fuel pump has two check valves in it, dirt under either can cause it to not pump.

Try removing the fuel line from the carb and blowing back through it to the fuel pump, if you can then both check valves are stuck open.

Then briefly crank the engine while holding a thumb over the fuel line, if you get no pressure and nothing more than a dribble of fuel the pump/valves are bad.

next try forcing air into the inlet of the fuel pump to blow it out, still with the line disconnected from the carb. Occasionally this will dislodge whatever was sticking the valves and you're good to go.

You could remove and disassemble the fuel pump side of the pump and clean the check valves if no luck otherwise.

In the future either use a fuel pump with the filter bowl on top (my favorite) or an inline filter before the pump.
