#1 of 22 Fuel Injection in 1991 Century
Sep 06, 2006 (3:38 pm)
I have a 1991 Century that I ran almost out of gas (it was literally chugging when I got to the station). Problem is, even though it has a full tank it's chugging like it's not getting enough gas. The check engine light hasn't come on yet, but I've gone from 30 mpg to about 18. I put in fuel injector cleaner, to no avail. What can I do short of taking it to the ol' garage?

Did you try changing the fuel filter. I had a 91 Century that I put over 300k miles on it with out any major work. It ran like a top till the kids in the hood stole it.

My 93 3.3L Century runs fine at idle but when you put in gear it hesitates and almost shuts off. Fuel pressure is running at 31 psi key on motor off and 31 psi motor on. Pulled vaccume line off of the fuel pressure reg and had no increase in psi and the motor died. Whats UP!!
Have replaced fuel filter.

The car quit running. Thought it was the fuel pump. Put in new pump. Still not running. I can put fuel in the motor and it runs. But i will not start without putting fuel in the motor.

must be a common problem, do all of the people who posted here have the V6? I have a 94, basically same model as all of you, same thing, chugging as though not getting enough gas, but it has a new fuel filter, I took it to the shop and they gave it a clean bill of health(after doing work on the fuel system)a few months later, its back to chugging and even stalling out once in a while. anyone figured out a fix for this let me know, thanks

How easy was it to change the fuel filter and where is located?

Fuel filter is located near the right rear wheel. You'll half to put the rear on stands and take off wheel to get to it. It is mounted on the frame. You will have to get the pressure of off the line before changing or you will get sprayed. I used a fuel pressure guage hooked to the fuel rail to bleed off the line pressure first. After pressure is gone there is a clip in front of and behind the filter. Just squeze the tabs and pull off. put in new filter and check for leaks. make sure the clips are locked in good.

i have the 93 3.3 v6 and mine is stuttering a lot and some times i get a code 44 - running lean and all the things it may entail.
I replaced my fuel filter and it didn't change, i have wondered if it may be my pump, which apparently does not prime.
#9 of 22 thinking of changing fuel pump buick century 94

was thinking of changing the fuel pump... car started stalling end of July in the high temps we were having here. Tried several ideas -- thought we had bad fuel -- changed fuel filter -- but problem has just progressively got worse. Is there an access port to change pump or do I have to drop the tank?... After reading some of the posts maybe changing the pump isn't the answer -- any ideas.
