98 buick century wont start FUEL PROBLEM
many fuel pumps get there power from the relay that is energized by the ECM
there is a pressure regulator in the system that will report to the ECM to switch on the fuel pump when the pressure falls
if you have no power to the relay , it could be because the pressure in the fuel system is above cut in pressure or that pressure regulator is not passing the current to the ECM

1998 buick century code p0420
code p 0420 refers to cat converter system bank 1---efficiency below threshold====causes ---cat converter---wiring---HO2S (heated oxygen sensor, the one in the exhaust manifold before the cat converter)
code p 0300 is random misfires
I would suggest changing the HO2S as it reports to the ECM on exhaust content so that the ECM can adjust the air/fuel ratio
so it is logical that if that unit is not reporting correctly, the cat converter may be having trouble burning off the gasses correctly
The oxygen sensor(O2S) reads the results of the cat converter operation and helps fine tune the ECM settings
