As one of the other comments called out, I was thinking - “just get a whole new assembly!”, assuming your labor to disassemble, diagnose and fix little parts would cost as much. But then I looked up the price of the pump assembly and immediately thought otherwise, especially when compared to only $70 for just the regulator. Add to that - you took the time to make a video, saving countless people a lot of money - not just with this issue, but in providing a better understanding of the component and system, as well as sharing diagnostic tactics and techniques that can be used elsewhere. You don’t get to bill for that. Just want you to know I appreciate it.

I see the same problem with my wife's Toyota Highlander. This gives me a good insight on what I have to do. Thanks.

This young man "gets it". I've operated my own shops as well as managed dealership service depts. albeit long before KZfaq was even an idea. Probably before algore invented the internet! I still work on family and friends iron when there is a need so it's nice to have a go-to resource from time to time. I have limited patience for the shade-tree guys with limited knowledge and a video camera that post junk. For sure will be saving Advanced Level Auto. Thanks Amigo!

Thank so much for this excellent video! I once used the cap from a highlighter (or you can use a Sharpie cap), to disconnect that same style Toyota fuel line: you cut off the closed end of the cap so you have about 2 inches of cap, then cut it lengthwise so you can slip it over the line. You then slip the cap on the line and push the cap in towards the connector while pushing the connector towards the cap and it will disconnect it. Just mentioning that for anyone who doesn't have the cool tool that you have! I wish Toyota would just install schrader values on the fuel rails to make pressure checks much easier. I really liked your video and especially liked that you trouble-shot the regulator. Great diagnosis! Thanks again!

My 2005 2.4 is doing the same. Not as bad as this, but on the way. Great video! 200,000 miles

Nobody really knows how to read fuel trims, I always have wondered how to know if there is a vacuum leak or not, that is a good way to tell, thank you!

Can't wait to tackle this fix! This video really gave me the confidence to know where to start and how to fix it.

I have really come to really enjoy your videos. Down to Earth, straight-forward, and easy to understand. You explain things well and appear to take good care of your customers. Thanks for bringing the great content. ~John

You make things really simple man. No one is out there who explains this that clear especially reading wiring diagram . Thanks

Great video as always. As someone who owns and wrenches on an almost 25 yr old car these sorts of diagnostics are super useful to get me in the right mindset when issues come up even if they aren't exactly ones you've covered.

Great video. Straight to the point. Good video angles. Much better than other youtubers who have too much useless dialogue. Keep it up!

I love your videos . You always explain everything you are doing. As a mechanic for close to 40 years, I know how hard it is to film while your working ,it takes a lot longer to do the job when filming ....and you do it well!

Thank you Eric. Good job. Have a blessed and safe week.

solved my problem. by far the best video that I have ever watched. fast, straight to the point and well explained. Thank you sir. This was my daughters car and you made a daddy look smart to his daughter.

Just got a 2002 highlander..thanks for a good education on the fuel pump, appreciate you

Another great video! Thanks for taking the time to show us this Eric!

It is AMAZING the level of clear detail explanation you give on this video man, I finally understood how exactly a fuel pump works, I'm having the exact same issue on a 2006 Corolla, so, I'll just jump to it!!! You Rock man!!!

thanks for making videos. at work you only can learn from what rolls into the shop, thanks to you and many other youtubers i can learn after work as well.

Wow. Straight forward and right to the point. I learned something here. Thank you!

You... sir....are a BEAST. I had the exact same scenario come in the shop and after seeing your diagnostic procedure I made quick work of it. Btw that fuel pressure tester setup is genius👌

Excellent. Fast and to the point with quick detailed narration. No fancy music or cut-scenes. Too bad that regulator wasn't in-line on the rail. I'm also surprised there isn't a check port on the rail as well. That's a nice bypass gauge you have. Thanks for the great video!

Thank you, thank you, thank you for this video! I'm having this same issue with my 2004 Camry with the same engine. I thought it was the fuel pump as well, so I changed it, but was still having the same issue.

Great video Eric! Customer should've brought it to you straight away. Thanks for sharing 👍👍

Great videos man . I fix stuff for a living so I can barely follow along . I dont think troubleshooting advance problems is for do it your selfer. Your video help professionals . Thank you very much .

Good Job sir! actually, Excellent Job mate!!! Mad proud of your diagnosis and fix!

Great video. I wouldn't have thought of that or known how to check and replace the regulator. Thank you for making it. Subscribed.

Excellent how to video. Really cool the way you use simple and high tech tools to diagnose the problem.

Awesome diagnostic video. Thank you and have a fun week.

You’re a straight shooter. I’ve used the old mouth pressure test thousands of times over the years. It can be a good tool used properly. Good work.

Great job, appreciate the pump breakdown!!

Excellent troubleshooting technique. Thank you for sharing.

You teach better than my teacher when I took Auto in school tanks boss from Los Angeles California

You can tell a Toyota a dry engine no leaks great 👍 job thanks for sharing you he deserve. a lot more subscribers

You probably wont make alot of money with your in depth process but we thank you!👍

Another fine video! I learned a lot from this one!

Thanks for another great video everyone is a learning curve 😁

Very good diagnosing. Keep up the good work and videos.

Another great diagnoses! All the best to you and your little girl! Hope working on your own is working out good!

It is always best to replace the fuel pump and the pressure regulator at the same time. Especially if it is on the fuel pump assembly in the fuel tank. Thank you for showing us how to troubleshoot it and repair it.

Great video, and excellent diagnosis. Keep up the good work. God Bless

The one i like this chanel is he show almost all the test and diag, tks so much sir and already subscribe and like for ur video.

Great diagnostic,step by step video

Honestly a great video. I will start looking into this on my dad's car

always something to learn from you thanks

Me llega tu forma de trabajar hermano, Dios te bendiga siempre, saludos desde Honduras 👍

These man is a technician these is the difference good job

I was thinking of going after the maf sensor when the fuel trims didn't get better at high rpm's. At that point I felt like it was a 50/50 shot for maf vs low fuel supply, but I suppose the long crank time is what steered you towards fuel. Great video!

Very nice troubleshooting and explaining.

Very detail. Good diagnosys.

I'm liking that fuel line tap, Great video

Excellent job of explaining and troubleshooting. It was a little bit puzzling as to why the check engine light didn't clear at the end, though!

You are great! Thank you very much 🙂, you got my problem solved.

That's why I always replace the whole module DONE! If they don't want to do that I send them on their merry way. I don't want to be the guy to be pulling the tank again(on cars that you have to pull the tank) when the fuel level sender or the regulator go bad 3K miles down the road. Great video bro! 👍

fantastic dissection of that fuel pump!

Excellent video, great explanation!

Good video, and thank for teaching, God bless you🙏👍👍👍👍👍👍👍👍👍👍👍👍👍👍

Very impressive diagnosis.

I have what I think is a check valve problem in the fuel system as it will start sometimes very easy and at other times it sounds like no compression I am pretty sure it is either a fuel pump check valve problem or the pump is intermittently working. Toyota issued a bulletin saying they were having a check valve problem, I have to find the connection point for checking fuel pump pressure , regulator and check valve it is a 2002 Tacoma with a 2.7 L engine and 200,000 miles and runs like new except for this problem. Thanks for your fantastic analyses one old wrench to another brilliant young one!

Excellent video. Good work

Hi a grain, and thinks for sharing your experience. I have more than cases like that, but I change the unit completely.

Enjoyed the information well explained Thanks

Had one of these in the shop recently with a fuel leak. Some jackass replaced the pump and lost the bolts that secure the fuel pump assembly to the tank. Instead of getting the proper bolts they used screws that were longer and the screws punctured holes all the way around the top of the tank. Some people have no common sense and should not be allowed to work on anything.

I learned this work I the same problem on Toyota Corolla 09 thanks you for your good work

Awesome tutorial. Thanks for sharing...

Very well explained.

That's the way it is done. Good job eria

Great job again like always

Very good vidéo. Keep up the good work. Cheers from new subscriber 👍

Nice job Eric! great video. Thanks for sharing brother. Catch ya on the next one

Love your videos. Love the way you show the fault and the correction. I was wondering where you got the tee to hook up your fuel gauge. Thanks again for great videos

Great job Eric.

Very useful video!!

Great video. Thanks brother

Thank you for taking your time and making these fantastic case study , it has helped me alot in the field , one of my many weak key factor point is I knever got my head around fuel trims and what they mean ? Could you please make a video in detail how they work , I am pretty confident it would help out alot other guys out. that would be awesome * from uk *

Really good video!

Great video! Thanks!

Nice diagnoses and repair

Good video, thanks for sharing

ERIC. Awesome/ great info that is all i am saying always some thing learn BRAVO and thanks for sharing.cheeeeeers Brotha

Well done great video .Smart thinking.

Great video, and good find!

great video keep them coming

Great video. Very informative..

"Dale otra vez" Great spanglish diagnostic. As always great case study , someone else would have replaced the Whole unit with out knowing with accuracy which part was broken.

Always , Thanks Eric , Cheers.

You are great diagnostician

Outstanding video.

Awesome, thank you so much for sharing.

Great job thank you for your great video

Thank you for sharing your videos I really enjoy watching them.

Well done as always

outstanding diagnostic Erick, keep it coming, by the way where can i get a hold of A pulsar.

Very good job

Another great video

Thanks for sharing Bro👍 You're awesome😎

Well done from Zimbabwe

LOL! 10:29 how slowly that needle crept up, haha! thanks for showing one method of checking the regulator, was curious how to check that, what an interesting find! was curious about deadheading the pump.. at the pump but thats pretty conclusive with the regulator! thanks for the share! looking forward to the next one!

Very helpful video for checking 2005 Rav4 with similar problem Few notes! 10:28 Toyota with MAF don't use prime , Toyota with MAP (98 Camry) primes the gas line for 2 seconds Misfires alone will be likely cleared but open coil circuit code means it needs a new coil.

Nice job 👍🏻

Great video...love that t adaptor.
