SOURCE: Where is the fuel filter located for Buick Century 2001
The fuel filter is located underneath the car in front of the gas tank.
You have release the fuel pressure. Remove the fuel filler cap, locate the fuel test port on the fuel rail on the passenger side on the end of the right real fuel rail for a 3.1L engine.
3.8L engine yhr test port is located at the pressure regulator under the trim cover.
SOURCE: I need to replace the
Husband found it but it did not solve the problem. But we can now hear the pump energize but the car still will not crank over and start. It acts like it is going to but just dies right away. This problem first started whenever I would go up the slightest incline, it would start running rough. Then on level surfaces it would go back to running fine and then one day it just would not start. Any suggestions?

The error that I'm showing for error code P1133 is
P1133 Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1(Rear Bank). I would suggest having both of your Oxygen Sensors replaced if you haven't already had that done. Hope this helps. Thanks for an honest rating and for using FixYa.
