95 buick century 6cylinder wagon bogs down, then hard to start  

Have you had the catalytic converter checked, when it gets stopped up it will bog your motor down also, a car model that age you can go ahead and disconnect the catalytic converter altogether, Also, you can check the fuel pump yourself, by disconnecting it at the carburater, then put a can to catch the gas when it comes out of the line, as you give the motor a couple of turns with the starter,(but only a couple of turns), you will see if it barely pumps out gas, its the fuel pump, if a lot of gas comes out , it's not the fuel pump!!
