you can try reversing the positive and negative wires to the pump (+ to -, -
to +) and crank the engine for a few seconds. this will make it pump in
reverse. sometimes when the fuel pump is clogged, running it in reverse for
a few seconds will clear it out. if not, you can try hitting it with a
hammer. seriously, this works too.
