Buick - Century :: Vacuum Leak To Fuel Pressure Regulator
Mar 8, 2012
I have a 1992 Buick Century with a 3.3L V6. I noticed a hissing sound under the hood with the motor running. The short vacuum hose (about 2 inches) connected at the fuel pressure regulator was loose and leaking. I shut the engine, remove the end of the hose and a little gas (about a teaspoon) came out of the vacuum pipe for awhile and then it stopped.
I tightened (but did not overtighten) the end of the hose with a nylon wire tie. There was no existing clamp on it. The vacuum leak stopped (no more hissing). Now, the car is sometimes hard to start or restart. Do I have a serious problem? Did I do the right thing? Could this be caused by a clogged fuel filter? (it was changed 42000 miles ago).

I have a leak in the fuel pressure regulator housing. Seems like a common problem. I ordered the new kit from FICMrepair.
While I wait for the new kit to arrive, is there any risk other than loosing a few mm of diesel fuel driving the van? Will the leak damage injectors?
It's not gushing out. I have smelled diesel fuel for the past 3 months and could not locate it until last weekend.
The kit is coming next week and I like driving the diesel van over my under powered 6 cylinder E150.
I want to clean out the EGR while I have everything apart. I have heard that some people just disconnect it. There is a write up about in the tech folder and it went way over my head.

After fixing my fuel pressure regulator leak, I found the fuel soaked track bar bushing coming apart.
The whole thing is available, but do the bushings are available? I've seen some poly kits for the '04 and older but nothing for the newer trucks. It's not a budget breaker either way, but it seem silly to throw away the giant bar because the bushing is shot.
If these will fit? 99-04 F250 Track Bar Bushings Red....

My car has been missing after a recent spark plug change, so i did a smoke test and i see smoke coming from under the air cleaner and i see that the accessory vacuum line goes under there, could this be the cause of the misfire? i already checked all the sparkplug work and wires. and if this could be the problem how would i get to it 1998 Buick century 3.1.

I have an Accel Gen vll EFI setup on a 59AB and plan on using a pressure regulator but it has a vacuum inlet fitting. I'm assuming it's to allow for more pressure on acceleration. When the vacum drops more fuel will be allowed into the fuel rail is my guess.

Today, my 1995 E150 suddenly started acting like it was running out of fuel Lucky for me, this happened close to both a parts store and my usual mechanic's shop. Unluckily for me, it happened on Saturday, and my shop can't get to it until Thursday. So here I am, hoping to do a fix in the meantime.
At first, it seemed that it must have been the fuel pump, because I couldn't hear it come on when I turned on the ignition. Then, a guy who said he was a mechanic told me he could hear the pump cycling, and that my problem was the fuel pressure regulator. So he managed to start the vehicle after a few tries, then it crapped out again. He did this twice. Then he went away.
I called every parts store in town, and none of them had a fuel pressure regulator for my vehicle, and the earliest any of them could get one was Monday. But I knew I was due for a fuel filter, and I'd changed filters on this vehicle before, so I got one of those and put it in. To my delight, the van started right up and idled beautifully. In fact, it ran beautifully for about 15 minutes, until I came to a slight rise, then it crapped out again. It still started up and idled smoothly, and even revved up smoothly, until it reached a high idle speed, at which point it crapped out. I did manage to limp into the parking lot of my shop - which, again, can't get to it until Thursday.
So my question is: does this sound like a fuel pressure regulator to you? If so, is that a job which somebody with a reasonable mechanical aptitude (i.e., at least good enough to change the fuel filter) should be able to feel safe doing? If the answer to those two is "yes" (or even if it's "no")....

I have a 1990 Ranger with a 4.0L that I just changer the intake gasket on. I broke the fuel line at the Fuel Pressure Regulator. Cant seem to find one anywhere. It is a nylon inside/rubber outside with a cloth mesh and quick connect fitting line. Where to get one? Can I hose clamp it the FPR by cutting off the connector that broke?

I have a 2000 Integra and now that it's cold I have a hard time starting it.The battery will run down before it starts.I replaced the plugs and it started right up.They were gas soaked.But again after sitting for awhile in the cold it wont start.Once I get it running and warmed up it runs great.Once it's running can pinch the fuel return line and it will shut down.Is this normal?It seems to be sending a lot of gas back to the tank.I think the fuel pressure regulator may be bad.I dont have afuel pressure guage to check the pressure but reading articles on the web about not starting and when it does start it bucks and dies I think the regulator is bad.

I took my fuel pressure regulator off hoping it would get to my green top coolant temp sensor. It doesn't Now when I put it back on its leaking? I didn't depressurize the fuel line first. Can this be the cause? If so do I just open the gas cap, pull the fuse for the fuel pump, and then re-insert the fuel pressure regulator? or do I need to get new O-rings for the regulator?

I have a 1994 Buick Century Wagon with a 3100 SFI V6 engine that I can't get to fire at all. I have read many posts with the same problem but haven't been able to find a follow up fix from them. My Buick just wouldn't start one day after running fine before. I came to this site and tried some of the suggested troubleshooting and found, while testing for power to fuel pump, that if I jumped from the battery to the gray wire on the fuel pump relay the car would start and run fine. So that rules out any fuel pump problems or fuel filter problems. I then swapped fuel pump relay to a different similar relay on the car and still wouldn't start. I have read on this site about the oil pressure/ fuel pressure switch being a possible cause and I believe I have found that switch. It is in the side of the block toward the front of car and has three wires, (orange, tan and gray) going into it.
I was going to try to jumper the orange to gray but didn't want to do the wrong jump in case of negatively effecting the EMC controller, usually green/white wire? I also heard of the crank shaft sensor located on the back side of block but am not sure of which of three sensors I'm seeing back there to test. I guess first I'm looking for proper jumping procedure. I tried jumping the gray to orange in the fuel pump relay but no good. I get 12 volts at that orange and for a couple of seconds 2 to 3 volts at the green/white wires at the fuel pump relay when ignition is turned on, so when I jump the orange to gray at the relay it should start as it does when I jumper from battery to gray. I had relay apart when I jumpered the orange to gray, do I have to jumper with relay together and use a pin/needle wire jumper so rest of relay wires are connected? The same would apply for jumper testing oil pressure switch and crank shaft sensor? If it's not the switch or sensor then it looks to maybe be the EMC?

Just changed the fuel pressure regulator on 1993 volvo 850 (non turbo), now the idle goes up and down then stalls.
Also changed IAC, but with a used one from a previously working car.

I've been having this code come up for a couple weeks now off and on. Currently I am stage 2 Giac. I have the autotech HPFP upgrade and was installed a couple months ago. Recently It threw the code and lasted for a couple days then went away. I notice that if i get on it pretty hard for a while the code will come back, im guessing due to lack of fuel. I pulled the fuel pump and checked the cam follower and it looks almost good as new still. Thought it would be the sensor but doesn't seem like it as the CEL turns off after a while of not getting on it.

1994 Buick Century 3.1
Fuel pump relay is not powering the fuel pump. I was able at one point to jump the orange wire to the gray wire but it will not even do that now. I know the fuel pump works because I can jump from the battery to the gray wire and it will turn on.
I used a multimeter and tested the volts from the orange wire on the relay to the neg post on the battery and it is only reading about 1.3 volts. Is this normal?
Checked the fuel pump 15a fuse and it is ok. I am getting spark. Could it be the crank sensor? How can I test that? (It is above the start I believe). Could it be the ignition control module? How to test? Location? What else can I test with the multimeter and post back with the results to further diagnose?

I have a 2006 S60 2.5T with 40k miles. My check engine light went on and stayed on for two drives. Then turned off and hasn't returned for next couple of drives. Error code says fuel pressure regulator. Should I bother to bring it to a mechanic or since the light went off (didn't burn out -- it momentarily turns on when I start the car) should I assume all is well?

I have a 2000 Ranger with the 3.0. Was wondering where the fuel pressure regulator is located on it. I like pictures.

My '90 240 will not start. When I turn the key to Acc. or Start I hear a whirring sound coming from the fuel pressure regulator so I assume the fuel pump is not an issue. The engine will not even crank. I assume it is the ignition coil or the starter but I am unsure. As an FYI, the battery and plugs are good.

My 94 B4000 (4.0L ohv)is acting weird. If I let it sit for more than a day, it won't start. I pop the intake tube off, squirt some gas in the plenum, and away she goes. It starts all day long after that. I can hear the fuel pump running. Is there a possibility there is a fuel pressure regulator leaking down, kinda like a pump losing it's prime? Or am I looking at dropping the tank for a new fuel pump??? It's getting close to winter up here (gonna snow anytime) and I don't need this kind of trouble when it's cold and snowy.

Buick Century 1987 - 2.8L
Sending unit measures: Empty 9 ohm - Full 88 ohm
Fuel pump working while engine is running or key switch in ON position (working properly).
Issue: Fuel needle fluctuates while car is in movement and the engine stops when the car is going downhill and suddenly is braked (half tank), Is normal this behaviour in this car? Is this car equipped with a 'anti-slosh module'? if yes, where it is located?
