- no diagnoses here, just an up close repair, saved an hour by not draining the coolant! labor time is 2.7hrs by the book.
rockauto.com part number, bosh 66813
end of video shows EVAP purge valve replacement. the brake switch wasn't shown but solution to code was it needed recalibration, zeroed back out via scan tool. someone replaced it before it seems. or, it lost it's positioning die to age. not sure but recalibrating adjusted the numbers😎

I totally enjoyed and appreciated this video presentation. It was very clear, the camera work was very good, which made it very easy to see what was being done. You continually explained what you were doing while you were doing it 👍, your speech was also very clear, and you didn't over talk or say too much. Great job, totally appreciate your skills.
Pro tip, but a cloth on the pipe underneath the regulator so you don’t get fuel all over it. Also, change gloves before touching the new one. Keep things as clean as possible.
Great video! Transverse mounted is so much easier. I just had to change one on a 2010 CTS! Much tighter space.
Best video on the subject, excellent camera angle!
Thank you for your time I sure was lost how to put the pressure pump on but looking at your video help me out a lot thank you brother I appreciate that
Thank you ever so much for this! This helps out a huge amount!
I have to give you a lot of credit for getting that bottom bolt out without removing that coolant pipe. I removed mine last night (waiting on the part to put it back together) and after about 15 minutes of messing with it I gave up and removed the pipe to give me a little more room to work. Even then it was a pain. Too bad because the rest of this job is so easy.
For others that are wondering if this was your issue, here were my symptoms and diagnostic. 2013 Buick Enclave, drove fine on the way home, went to leave an hour later and it was sputtering bad, flashing check engine and stabilitrak message. Threw code P228C and P00C6. P228C = Fuel Pressure Regulator 1 Exceeded Control Limits - Pressure Too Low, P00C6 = Engine Fuel Rail Pressure Low. Hook up my WiFi OBD adapter and fired up the OBD Fusion app on my iphone and setup logs on Fuel Pressure Rail and Fuel Pressure Rail Gauge. One of those is the pressure before the high pressure pump and one of them is the pressure after (sorry, I forgot which was which now). On my car they were both basically the same pressure, around 60 PSI meaning it was only getting pressure from the low pressure pump in the tank. My buddy happens to have a 2015 Acadia, which is the same car as the Enclave, so to make sure I was logging the right PIDs I ran the same logs on his car and one was 60 PSI while the other was going between 600 and 800 PSI. So the problem is either the pump failed or the pressure sensor on the pump failed. The pressure sensor for the high pressure pump is built into the pump and isn't serviceable so that was pretty much the end of diagnostics.

Thank you for the realistic video,an your showing of every step, appreciate you, I am having a problem with my Buick Enclave, small misfire left to clear,hope I don't have to go to that step but can do it now Thanks to your video.
Thanks
At least you have codes. My nieces' husband thought it was the battery since it died on the road while driving. So after putting the wrong battery in it, it came out of a truck, didn't work. In more ways than one. I charged and tested the old battery which is fine. Of course all the codes where cleared, if it had any. Put my reader on it and looked at voltage, fuel rail pressure and fuel gauge pressure. Both pressures would fluctuate between 56 and 70 psi. So I found the issue pretty quick. Just waiting on the part.
Great Job!! I appreciated it and enjoy the video!!!!!!
I wish we could see footage of your diagnostics process, and how you come to the conclusion that it needs a pump, ect.. My 3 favorite channels are "Pine Hollow Auto Diagnostics" -- "South Main Auto" -- "Watch Wes Work".... These guys show all the diag and troubleshooting breakdowns and it makes really good videos. If you ever wanted to add more videos to your channel, this is a good way to do it. I've learned so much just by watching these guys too. If you've never heard of their channels, I'd check it out, just for the knowledge expansion alone.
Then go on there page 🤦🏻♂️
Maybe he’s just a part changer
If you hook an obd2 reader it will show the fuel pressure going haywyre sitting at idle. You’ll have reduced power, weird noises, rich exhaust smells.
@@JordanBlue1 Hello brother, I hope you can help me, I have the code p0087 and p0089, I changed the 6 injectors because they were bad but I still have a lot of smoke in the exhaust with a lot of gasoline smell, when I turn the key the fuel pump turns on but I see on the scanner that the rail pressure drops very fast, could it be the high pressure pump? (I hope you understand me, I don't speak English)
@@JordanBlue1 Do you know what the normal operating pressure should be at the rail, or what constitutes going haywire? I've been chasing a misfire code forever on my wife's '09 Acadia and I'm just getting misfire codes and cat inefficiency.
Total labor wasting parts designs. Mechanics love beating the book time and still getting paid book time...for being good, better or best, fully warranted, win win.
Nice shots, nice job.
very helpful video .. which reader are you using?
Love your channel since i'm a bodybuilding also
I am having problems getting to high pressure pump in what do i have to do ???
Thanks for the video. it was very good .i just put the same pump on today. Now when ii give it gas it boggs down. Starts good ,what should i do next.i changed all the sensors and sparkplugs, thanks
Dang it, I just bought a 2011 Arcadia that starts fine but won't go over 15 mph. Lady I bought it from told me the shop told her it was the fuel pump. I'm guessing the High pressure pump since it idles fine. There's a seperate computer just for the fuel pump in these, It's around $100 on Rockauto from my earlier investigation. I think it's called a fuel pump control module. Mine isn't throwing any codes at all. Did you maybe forget to plug yours in? If not maybe you need the control module too.
Obviously he does not know the existence of longer lug nut sockets or extensions.
My is leaking right by the sensor conector wat ur doing for unto change it let me know why
I have a 2009 Chevy Traverse. It shut off on me while at the red light. No check engine light, got it scanned. Codes said Ignition coils. Ended up changing the throttle body, got a tuneup. Could it be the fuel pump that's causing the issue?
Hey there, I'll need more details...
After the replacement, have you cleared the codes and seen any immediate comebacks?
Also... is it rotating and trying to start? Is it not?
If it's cracking and not starting, try spraying supplemental fuel into the throttle body, if it starts, you have a fuel related issue. If not, check other things
@@partsshooter Hey, thanks for the tips. It runs great now. Cleared the codes like you suggested. Nothing else came up since. Only other thing I really was concerned about was the battery voltage. It'll start at 14 then after a while it'll stay between 12-14. Sometimes just sitting right at 14, should I be concerned?
hello do you have to relieve the pressure so lots of fuel doesn't come out
Great video! Did you get codes p0087 and p0089?
Hello brother, what was the solution to these codes? I have the same codes
How many miles???
Acadia 2010
What if the follower doesn’t come out? I’m being told that’s a problem that’s going to cost 1000s to fix. 🤦🏽♀️
Put a magnet behind it and see if it drags it out
@@partsshooter ok thank you 💙
Where you buy the fuel pressure regulator
Rock Auto
It may be inside the high pressure fuel pump if you can't find the part anywhere.
my 2010 cranks but won't start .. I replaced all the coils, plugs, cam shaft sensors still not starting. I doubt the fuel pump. I tested the pressure it shows 60 PSI .. still did not replace the high pressure fuel pump .. could it be the fault ?
What codes are present?
@@partsshooter unfortunately the codes were erased after disconnecting the battery. However when trying to start all and after many times it shows bad cam shaft sensors. I replaced them but still the same issue.
@@partsshooter now the remaining un changed items the fuel pump and the high pressure fuel pump
@@jasimalbalushi
How's your engine oil level?
Try holding the gas pedal all the way down while starting, flood clear.
have you added starter fluid to intake? See if you're missing fuel.
You may have bad crank sensor or jumped timing.
Try those 2 things 1st, let me know what happens
@@partsshooter the engine oil level is ok
I tried holding the gas pedal all the way down and it would start but with rough start and shaking and once I switch on back it won't start again .. only after a lot of tries and it will die immediately if it starts
I did not try adding started fluid but tested the gas pressure and it showed 60 PSI and I tried to bypass the high pressure fuel pump but same results
I replace the crank sensor but same results
For the timing the engine was running fine when I bought it but there were missing fire codes in bank one .. I replace the coils and plugs and then the problem increased
Can this cause the oxygen sensor and the cat coverter to go bad?
Yes, assuming o2 sensor get stuck rich, a rich mixture mixture can accelerate the amount of heat in converter. If it get too hot too long, material will melt.
@@partsshooter how do I know if thebfuel pump is bad? Cat converter and oxygen sensor was replaced and now they are bad again.
@@elkuartostudio if you're having p0420/00430 check your sensor function and fuel trims. Because there maybe other underlying causes.
This issue isn't exactly cut and dry. I need lots of info. Try uploading a video with PID data and everything you discovered and I'll be happy to chime in
@@partsshooter
I have no codes for that. Only codes are for the oxygen sensor and cat converter.
@@elkuartostudio ok, check live stream data and make sure the a/f or oxygen sensor aren't matching, up and downstream shouldn't oscillate or match values.
Make sure the sensors aren't flat lining or stuck values. If all check out, replace cats. They're likely interior, this happens
Mans need a zipper ratchet and off set wrenchs
When you replace the pump because it is a high pressure, do you have to do anything special?
No... nothing special
Appreciate you answering back! I have a question maybe you can help me my car engine light came on and bounch of codes so I took it to a mechanic quote me for 1800 hundred dollars to raplace it and some oxygen sensors! What can you recommend?
@@tzilacatzin1600 I'll need more details
@Parts shooter I have codes po305 , po300, po303, po301! Right now it drive just fine!
@@tzilacatzin1600 interesting... simply sound like bad spark plugs! Like essecive gap and extremely worn. Assuming they were changed, they still should be pulled and inspected. They tell a story of what's happening inside combustion chamber.
Could also have been water in gas... rare but can affect combustion due to fuel quality. Pulling plugs will reveal this plausibly also.
MultipleSingular Misfires codes are generated from most likely tune up negligence.
(MAKE NOTE) the above is primarily stating to check plug condition to determine environmental circumstances.
To get more in depth, because your odd bank is affected, you could have timing issues... head gasket issues...or o2 sensor issue on that bank! With the complexities of modern vehicles it's not just 1 thing nowadays.
If I was you, I'd get a second opinion of who can physically diagnose it
That bottom bolt is a bitch to get to
Excessive use of E85 fuel can result in reduced engine power, MIL on and DTC P228C (fuel pressure regulator control performance - low pressure) set in the ECM as current or history.
I beg to differ...
@@partsshooter it happened to me,I put regular gas in the tank and code was no longer showing up in scanner also engine light went after one day
What’s E85 fuel? The new kind vs the old 100% gasoline?
My acadia tarda en encender puede ser el regulator?
Es un sensor que esta junto a LA garganta del acelerador
Es el ultimate sensor que cambio el Chavo
Impossible to find in my acadia 2007...nothing...
What prompted you to know thats exact part what symptoms did the car have
Sorry I didn't document diagnoses, people typically just want answers. Diagnosing, people don't have the attention span for it mostly.
But to answer your question, In the scan tool, you go into pcm and In the live data, you'll see "high pressure fuel pump DESIRE".... and you'll match it with the "high pressure fuel pump actual" PID (parameter identification) if they aren't matching, you then go into a testing function and further isolate issue.
Example, if pcm desire 600psi the actual value should be at 600psi -+3psi
If the fuel pump value can't stabilize, replace fuel pump.
There's more involve but this is the gist
