Thanks. I have a 98 Buick Century and it's sputtering frequently. The fuel filter has been replaced, spark plugs and wires. 2 coil packs. Cannister purge valve. And new crank shaft sensor. Cpl of these threw codes. I'm praying to replace that regulator, and hopefully fix my issue. You did a great job teaching how to go through it. Thanks!!
You saved me a bunch of money and head ache. My car was doing the exact same thing and this completely fixed it. Thank you! My local mechanic was stumped
Dude! Thanks for the info!
This worked to fix rough idle and start for me too!
Previous to that I replaced fuel pump & filter, spark plugs and wires, ignition module and all 3 coil packs (was getting P0300 code before that), and IAC valve
Thank You ! Fuel pressure regulator that has old leaky diapham a common problem on many cars, duelly noted.
Dan you are the man for all the information you are giving for free. Great job buddy.👍🏾👍🏾👍🏾
Thanks so much !
Thank you for the video. I’ve replaced the fuel pump, fuel filter, IAC, TPS, plus and wires, and pcv hoses/ valve. Haven’t had a code at all. I’m going to give this a go!
Glad it helped
Love the Buick! They always have such a smooth ride. Thanks Big Dan! Always educational. Take care.
Hey HS ! Thank you for stopping bye buddy I hope you you and your wife have a great day
Very well explained best video I seen yet. Thanks Brother...
Very close to three years ago now I got my parents’ sitting 99 Cutlass for my 18th birthday. I was too stubborn to pay someone else to work on it so that car is what got me into mechanics, which is now my heart’s trade besides serving the Lord.
It was sitting for about 3-4 years before I ran it the first time, it ended up needing a head gasket job and for some reason it wouldn’t start, it had sat another 1.5-2 years before I first cranked it after disassembly. After testing other systems, I determined that there’s a fuel pressure drop and when you pinch off the return side it doesn’t drop pressure nearly as bad AND it goes above spec. It’s most definitely aiming towards it finally running again after I get a new FPR installed.
Great Story thanks for commenting
Just picked one up yesterday for cheap went around fine yesterday for a couple hours besides a bit of a rough idle and the lagging start but started fine after work went out today stalled 3 times within a 20 minute trip so I’m definitely going to start With the regulator
Great info Thank you ! I was thinking of trying this next after replacing my fuel filter which didn’t fix the problem.
Good luck
Me too. But mine needed to be replaced badly. It's got 149,000 on it don't think previous owner ever replaced it. It was nasty.
I enjoyed this video
Thank you !
Good to see you man!
Bill ! Thanks man ! Glad your still around man !
@@Gasolinegarage always here supporting you buddy even when you take long breaks. Been here for years man haha 👍
I hope you are right I have my fingers crossed our symptoms are very similar. I ordered the part today
Good luck let me know if it works to help other people out !
@@Gasolinegarage I’m a good worker but a terrible troubleshooter I have high hopes for my century wagon to live up to its dreams of being a reliable family wagon
God bless you
I have a 1991 cutlass supreme and I can’t seem to find mine idk if I half to drop my fuel tank
Just dropped in to say Hi! Hope you and the family are doing well. 👍😀
Thank you everyone is good hope all is well with u as well !
All is well with me also. Thanks.
appreciate.
Where does the fuel pressure vacuum hose connect to the other end of the
I wonder if I need o.e.m. on mine? or will a substitute cheaper work?
this even helped with a 2001 f150 5.4 hard start, intermitted stalling
Awesome!
You don't need to do any of that you just can take off your cruise control off then take off the regulator off from the block
Mine had no throttle response couldn’t get over 30 mph and stalling, installed new throttle position sensor ran great for one day and right back to running rough stalling no acceleration any tips would be appreciated 👍
You might want to start with this fuel regulator it might have something to do with it
Same symptoms. Also get intermittent P0405 code...
Can this problem be alsow in a 3.1 v6 Buick from 1989 ??
Yes it Possibly could be
Thank you very much nice video i don't have that problem but my car is consumingA lot of gas i can say less 300 miles per tank what do you suggest thanks
You might want to start with this or do a tuneup spark plugs wires air filter all that stuff
my son will do mine I hope he has time ECT. mine has a weird looking screw to it. sorta long like a special adjust type screw.
Hope it works out for you
Are those 3100 engines dependable, recently bought a 03 Malibu and it has 160000 miles and starts right up and doesn’t seem to burn oil?
Very …My car currently has 152,000 miles still running strong
I have a 98 Chevy Lumina and it dies randomly while driving and also hard to start in the morning could this be my culprit looking forward to your response thanks
If you haven’t changed any other part that I mentioned in the video I would definitely start with this one probably will solve most if not all of your problems
The regulator comes right out with the line still attached..just disconnect the quick connect & take out the torx nut on regulator leave the big nut & pull it out at the fuel rail ..it will come out without taking anything else off..sometimes that nut will be frozen on the line so its better to remove it from the fuel rail cause you can bend or break the mount..just wiggle & turn it she comes out
Thanks for the information man I hope this helps somebody else
My 04 century is in the shop right now, hard start, poor acceleration, fuel mileage in the toilet.
They just called and said it’s finished and they replaced the fuel pressure “sensor” I wonder if they mean this regulator.
My only concern is I did hear the fuel pump whining last week. Fingers crossed they’ve got it whooped if not I guess the pump will be next.
Well definitely dont think this is my issue. My buick instantly starts when its cold, and then itll struggle to start later in the day (has yet to actually not start though, just cranks for a while) no idea what the issue is
Is it necessary to relieve the fuel pressure prior to removal?
There is a Schrader valve on the line going to the intake you can relieve the pressure there but as soon as you crack the line it will start leaking fuel
If the regulator is bad then the fuel pressure is lost after turned off..thats a clue you have a problem ..if you stop the motor wait 5 minutes & check if there is pressure
Could you possibly do a 3.1 instead of a 3100?
😂
I have a 2003 buick century I have these problems plus I smell gas from the front if vehicle
Try the regulator first and go from there this might be your problem
Was this your issue? I've got the same problems Dan listed, plus the strong gas smell you referenced.
I changed my thermostat an now my car sounds like its drowning an wont start then once i checked th bottom two line an it started running like my throttle was stuck
I’m not too sure about that problem but maybe if someone’s watching can help you out
mine starts fine cold. but sometimes hard when hot? what gives?
That can still be the fuel pressure regulator he might want to start there
@@Gasolinegarage i appreciate.
once I see all that im gonna pay $50 to let my mechanic do it
Damn a mechanic that only charges $50 these days is a rarity. Keep that guy on good terms.
What about stalling?
The only thing I had a problem with with sometimes it wouldn’t start on the first key turn
So how did you know it was the fuel pressure regulator.?…
Research
