next!! no fuel gauge

ok so i grounded out the wire to the fuel sender and the guage never moved. i then grounded the wire out to the factory temp sender it didn't move either. i then pulled the cluster changed the regulater, checked all conection and cleaned all conections put every thing back together and now the temp gauge works but still no fuel. i ground the wire again at still doesn't move. i got my multi meter out and i have no voltage at all coming through that wire so my problem is in a wire or that path in the board on the cluster? is there anyone who has a wiring schematic for this or do i jsut need to chase it myself
