I watched a lot of videos off ppl taking a lot of other parts off just to get to the part u had is so simple thanks
Thanks Izzy. I did this last year and forgot to comment. Your method was a life saver, I agree your the #1 DIY guru!
Thanks man. Glad the video helped. Your feedback is greatly appreciated.
Izzy thanks for the video, it really helps when you can watch the job being done before you get into the repair, I thought I would have to take the valve body off for clearance, the video saved me a lot of work, my car would stall on deceleration, and the diaphram was leaking fuel like yours, it run like a champ now, wish you the best Luis.
Thanks Luis! . . glad the video helped! . . . Thanks for your comment, and Best regards to you and yours as well.
very nice performance there partner!!!! thank you for sharing I will be following that procedure soon Excellent Job.....
You're welcome man! . . Thanks for the comment . . . and good luck with your project!
where this video disappeared i am searching for long time ago, i wish i found it before i failed to remove my malibu's regulator even i was turning both spanners in the reverse direction lol. thank you very match sir!
Very detailed and thorough video - thanks!
I'm ready to do this to my 2004 Montana now
Thank you! . . . Good for you!
. . Good luck with your project, and thanks for commenting.
Yeah Great video, explained well. Now I won't look like a moron when I do this in front of my father in law at his shop. Saving marriages and cars Izzy. Thanks.
You're welcome. Glad you liked it. Those in-law's can be brutal. Believe me, I know! Thanks for the feedback.
Good video, and very helpful, thank you for making it, and posting it. It's much appreciated!!
Glad you liked it! . . Thanks for the feedback.
Thank you for making that easy and clear. Great vid.
You're welcome Nick. Thanks for your feedback.
Thank you I have a 2000 Oldsmobile Alero 2door and this is what’s leaking fuel
Great vid! Dude! Thanks for sharing! 👍🏻👍🏻
Great video! Thank u for the knowledge! DIY for life.
You're Welcome! . . Glad i was able to help. Thanks for your comment also. . . it is greatly appreciated.
I have the 3100 v6 but it is giving off purple smoke what do you think it could be?
Thank you! Hoping my 94 Ciera has that flexible line as well. Setup looks identical. Dropped my t30 bolt already down it went, never to be seen again. 🙀 pullapart to the rescue.
I really need to know what is the part next to the fuel regulator on my 05 grand am I think it's dealing with air and fuel mixture car won't start
Nice vid. Thanks Izzy!
You're welcome. Thank you for commenting. Glad you liked it.
if battery disconnected+ is it a long relearn? so remove fuse and run until dies to depressurize
mine is giving off purple smoke when I accelarate what could it be?
Thanks for this tip and tool. I needed to replace my regulator and wasn't looking forward to having to pull the upper intake plenum and fuel rail. At first I couldn't get the regulator to come up as high as you do in this video. My fuel lines are clipped together with a metal clip that's bolted to the engine so I was thinking there's no way it will come up, but with some wiggling it finally did. Then I could just barely get my wrenches on there to do the work. Perfect!
Good show Justin! . . Glad you got it done. It's a real pain to have to remove all that stuff just to replace a little-old regulator. Thanks for commenting.
I do have one question for you. I noticed the silver bracket on the fuel rail that the silver screw goes into seems to have a rubber gasket attached to it in your video, but I didn't have that on my car. Did I loose something?
Never mind. I thought it was a rubber spacer, but I can see now that its actually just part of the metal piece itself.
Did mine on my 2004 Pontiac Montana with same engine.
I had to back off the bolt that holds part of air intake to the intake plennum. The end of the bolt protruded enough to block the regulator from coming out. PITA because I could only turn it 1/8 turn at a time. My ratcheting box end wouldn't fit.
Glad you mentioned vacuum hose fitting not being snug. I ran down to parts store and got an assortment for $5. Pulled off the old one and new one fit perfectly.
I had the nut on the fuel line slide down aways, another PITA to slide it back up.
But in all this is a very helpful video.
Good job!
Great vid,small ziptie or a bit of electric tape wrapped around the stem to seal vacuum tube ?
Excellent video !
Thank you my friend. Glad you approve. Thanks for the feedback!
Thanks IZZY. What a great help.
You're welcome! . . Glad you found the video helpful. Thanks for your comment.
Thank you. I actually did watch a video about taking all the other stuff off before I saw this, so this looks easier. The only question I have is will this fuel line come loose wiggling it and pulling it that much down towards back center in there?
Love your video
Very therough explanations
Thanks my friend. Glad you liked it!
Will help my olds cutlass supreme with 3100 engine because it will start up and immediately shut off. I have put in new injectors
Why cant i move my regulator around like u can. I have a 2005 impala 3400. Theres a bolt from the throttle body.
Ware does the end of this hose connect
Have done the job once ,about to have to do it again will be the 3rd regulator this car has had ,1 by the dealer and 2 by me i loosened of the the throttle body to get the clearance to slide the regulator out side ways, very tight fit was scared to death the fuel line fitting would break ,also 24 mm is not a common size bought 2 open end wrenchs at home depot problem was they were very big , ended up using 1 and a small adjustable wrench .
Good for you. Glad you got it done. Some cars can be a pain. You're the man!
I know this is too late for your case but for anyone else. 15/16" is the same as 24mm for future reference. Thanks for the video Izzy.
good vid helped me alot
Glad to hear that. Thanks for your comment!
Great video Izzy. I think this is what's wrong with my 2004 Pontiac Montana. I had a random misfire and then a crank no start condition. I checked ignition, crank sensor, coils all good. When I checked fuel pressure all I got was 37 to 42 PSI on key on but drop pressure immediately so I knew the fuel rails not keeping pressure. So injectors not getting fuel to atomize the cylinders *no start contion. I then smelled fuel so I was looking for a leak I didn't find any leaks at the fuel regulator but when I checked botton of engine I saw a stream of fuel coming out of the exhaust resonator NOT GOOD!!! So I suspect fuel regulator is culprit allowing raw fuel to run into intake and then pushed through exhaust. Could this be a possible diagnosis?
Two ways raw fuel can find its way into the intake: 1- A ruptured fuel regulator vacuum diaphragm. 2- Leaky fuel injectors. To test the diaphragm, pull out the vacuum hose and look for fuel, there shouldn't be any. You can also use a vacuum pump to test the diaphragm. It should hold a vacuum. If the injectors are leaking, that could make it hard to start specially when the engine is hot do to the excess fuel in the intake. To do a proper diagnosis on the fuel system you will need a fuel pressure tester and maybe an injector pulser. Good luck, hope it helps!
Are the 3400’s the exact same as the 3100
Thank you, Izzy. Nice sound quality, too. Just asking, but, "in the field" fix advice, what would you do when the replacement part doesn't fit that vacuum hose (more expensive!) and the parts store is closed (and it's 20+ miles away) and you need your car to work? Do you wrap some high temp tape to make the fitting grab better? put a really thin hose sleeve over the new part? get a hose adapter? :-) Best wishes.
Electrical tape over the fitting could be a quick fix. I have used a zip tie in the past to fix a lose fitting hose. When you make it to the store, the "HELP" section should have a fitting that should fit. Good luck, and thanks for the feedback!
huh too quiet
do you have to leave the vacuum hose off when you depressurize ?
You can leave it on. The engine will run until there is no more fuel pressure.
I have a very high idle when either sitting at light in drive and when in park.. what may that be?? I’ve been changing injectors and also the FPR but it has not fixed my problem.. any ideas??
None of the components you mentioned have anything to do with the idle speed. You need to do a proper diagnosis instead of replacing parts. The ECU regulates the idle speed in late model cars. There are other components that can affect the idle speed like the idle air control valve and others than when malfunctioning can fool the computer or make it react to to the malfunction in an effort to mitigate the problem.
nice wrench. adjustable
i tried this on a 2004 grand am gt and i got to where i couldnt get the regulator to come up high enough to get 24mm wrenches on it so i gave up and put it back together, is there a way of getting the regulator to come up higher
This really depends on the car. The fuel tubes are usually fairly flexible in the way they are mounted. These are also normally guided in the intended direction with plastic or metal clips somewhere along their trajectory. Try to carefully detach the tubes from the clips and see if you can get the clearance.
on my motor everything is really small tight quarters and cant see or find clips holding the metal tubing, i tried for a good 10 minites wiggling regulator and didnt gain any clearance, clips have to be down in an area to where they are unable to reach, i came to conclusion i will have to remove mass air intake and boot and the throttle assembly and brackets to get to the nut on the bottom of regulator
@@robertrine1522 Did you get around to getting yours done?...I have the same car and I had the same issue--finally I was able to loosen the nut with the FPR attached. I removed the engine hoist bracket and held the throttle up with a string to gain just enough clearance first.
What is the capped one ?
Hey Ashley, I think that is a test port.
The problem I ran into is the regulator from Autozone I had to replace twice because they were bad out of the box. Go Sorensen makes good products it was just luck of the draw.
I hear you, it's a good idea to test the fuel system again after installation to make sure the regulator is working correctly. Thanks for the feedback!
I really need to know the kind of ratchet and but you used to take the regulator off please.
I cover everything about the ratchet and where to get it in the video.
the smell of gas inside he car sometimes , could it be this the fuel pressure regulator need replacing?
It could be. But it could also be a bunch of other things, such as a problem with the Evap. System. Hard to tell without a proper diagnosis. Try to find the source of the smell.
What was your bad fuel pressure regulator making clicking noises while it went bad 97 Pontiac Bonneville is making clicking noises when turning the key to the on position is this an indication the fuel pressure regulator is bad and should be replaced
Not necessarily. This one had fuel in the vacuum chamber (just one of the possible symptoms). There are several tests that should be performed before condemning it. Is the car exhibiting any other symptoms?
F***ing Haynes Manual instructs to remove the upper manifold/throttle body.
You even tell me where to get the tools!
You just saved me a weekend buddy!
I hear you. Even some so called "techs" at repair shops guide you to remove a bunch of unnecessary stuff. Maybe in an effort to discourage the DIYers and opt to take it to a repair shop. Glad to hear it was helpful. Thanks for your comment.
Hi, good video!!
Question?? so do you think is good to change the fuel pressure regulator, every 50 or 60 miles, I got a Toyota 4runner, 99 .....thank you!!
+Danny Chuqui: Well, I normally follow Murphy's Law: "If it ain't broke, don't fix it". If you are not having any issues, such as hard starting, long crank times, hesitation under acceleration, or fuel trim issues, or if you disconnect the vacuum line and no fuel comes out, I would leave it alone. You're Welcome! . . Thanks for your comment!
When doing this. Can you just disconnect the battery completely?
Sure. Always disconnect NEGATIVE first and when re-connecting, connect NEGATIVE last.
Thanks man. Fixn have to do all this to a 2003 Chevy Malibu.
get oem regulator vac hose will fit fine.
Okay enough about the tools I think everyone had that part figured out or they wouldn’t be working on the car
same bs with the pcv valve.. my elbow didnt fit tight either..goddamn gm
Symptoms
Thats why aftermarket parts are usually a pain to work with. They make one part to fit many cars, and then the vacuum lines don't fit.
So basically fixed one problem, and maufacturers of the part created another little problem, which is an easy fix, but just stupid. (not this guys fault). thanks aftermarket makers , you guys suck !!!
He could have figured that out, before he started.
@@omardoomer944 you don’t know till you take most stuff apart
you could have checked if vacuum hose fit onto regulator without taking anything apart. Thought that was your problem. I just checked mine and it fits fine. now just have to replace it. @@raiderman28
Blah blah blah get to the point! If we want to look at tools we'll go to a tool show! GEEZ! Although skipping through your video I was able to see what I wanted to see, I was handed one of these motors in pieces and putting it back together.
My lord he's hard to listen to
mine is giving off purple smoke when I accelarate what could it be?
I have the 3100 v6 but it is giving off purple smoke what do you think it could be?
Oil
mine is giving off purple smoke when I accelarate what could it be?
Would that be BLUE smoke?
Well kind of purple but you can say blue I am not 100% sure but what could that be?
There are 3 fluids that can find there way into the combustion chamber. The first one belongs there, (which is fuel) but when in excess (too rich a mixture) will cause BLACK smoke from un-burned hydrocarbons. The second is oil, will will produce a BLUISH smoke, due to oil going past the rings or past worn valve guide seals. The third is coolant/antifreeze, which will produce what looks like WHITE smoke, but is really STEAM from the coolant finding its way into the combustion chamber, usually due to a blown head gasket or cracked block and in some engines could be due to a blown intake manifold gasket, like on the GM 3800 engines.
thanks Izzy so I guess its oil cuz it does run out of oil every once and a while so I will have to check out the ring thanks
You're Welcome. Good Luck, and Thanks for your comment!
