Okay I really want to try Good Chop, but I work for a Large beef processor from Liberal.nGotta make sure there isn't a rule about that. I know Pepsi is that bad I walked into a friend's home in the early 2000's and she worked for Pepsi and I had a Coke her boss was there and he flipped out she almost got fired
I’m 27 and have been a mechanic for about 7 years now and I always love it when you post these types of videos. I’ve learned a lot by just watching these and will continue to keep finding every way to learn new tips like these. Keep up the good work carwizard❤❤
@@Hotrod1965 I mean at my shop we do that too but I take the time to actually figure out why these things go bad and watching his videos has really helped me on certain situations. Thanks for your reply
I disagree with part when you said anyone. No not anyone can replace wheel bearing or replace axle or even change brakes. Most of my neighbors don’t have or know how to use screwdriver 👍🏻
A good and honest mechanic is worth their weight in gold. And unfortunately, my trusted mechanic/shop owner and friend of 35 years recently passed away. He was another one of those gurus who was able to fix what other shops couldn't or wouldn't. Gas, diesel, EVs, hybrids... cars, trucks, large trucks, semis and even small aircraft. Engine and tranny rebuilds too. No job was too small or two big. He was the best with certifications out his butt. A good friend is impossible to replace.... a good mechanic is almost as hard.
Car wizard, I’m US Navy retired, I’ve worked on aircraft for 46 years and it is so easy to see the sh that think they know everything. I love your channel and most of all thank you for your service.
I think the answer to your question about why it's hard to find good mechanics is in how Daniel-San worked this problem. Before anything, he needed to find a fault that fit all the symptoms AND with his overall knowledge. The big negative fuel trim numbers were key because it leads to the question: "Where is all that extra fuel coming from?" Knowing that the ECU was cutting fuel to the injectors, he's left with the only remaining source: the PCV system. He also knows from the Internet that the HP pump can leak fuel into the crankcase. Finally, he asks: "Does this explain everything the customer reported?" The answer is "yes" and he knows what to do. This methodical approach takes longer and requires deeper understanding. It's a lot easier and faster to do a couple of searches and imitate. If you don't really understand how things work, imitation is about all you can do. If the search uncovers multiple options and you don't know which one is right, you can either guess and risk fixing the wrong thing or you can punt. Those other two shops punted. To be a really good mechanic, I think you need a solid understanding of how cars work and the discipline to find faults that explain everything you're seeing.
Problem is shops could. But spending so much time chasing diagnostics is a good way to go out of business. How long and how much work to deduce this? Imagine getting a bill for several hours of diagnostics. Only reason Wizard found it is because somebody else took the hit. 'We cant figure it out' is another way of saying 'we dont want to fix this problem'
@@russelljacob7955- The root cause of what you describe is the mechanics are not really mechanics. They are code readers & have no clue what to do with the information they find. That falls on the shop management, in not training their people to learn what to do with the valuable data they acquire.
@@cmdrdarwin3682 Is it? Is just knowledge. How long would it take any of us without having worked on the vehicle prior to have come to this determination? Yeah, is simple to state after the fact. How long to get to that determination? Then verifying too. After a few hours, one might be able to determine that fuel is getting in crankcase. Then what? Testing and checking all cylinders because assume maybe an injector issue or what? Whomever figured it out the first time was somebody who has ripped apart an engine. Perhaps in parts cannon to solve the issue. How many would even think that fuel pump sealed to crankcase. I cite an example of my own personal car from years ago. Brakes felt off. Weak and mushy. Cause? Cause was a leak where intake manifold sealed to block on a GM 3.1 v6. I really dislike wizard for the assertions he was making. The only thing other shops did wrong was not having that database wizard did and not wanting to take on the liability. Wizard has said it himself about things he wont do, wont touch. Does that make him a bad mechanic?
@@russelljacob7955 I agree with what you're saying. I'm a mobile mechanic and I have across cars where I've fixed issues that other shops could not fix. But I've also been in a situation where I couldn't fix a problem a customer was having. I could have spend hour wasting the customer time and money, or be honest (which they really appreciate) and tell the customer I've exhausted all my resources and cannot fix the issue. Does that make me a bad mechanic? I don't think it does. I'm more worried about gorilla mechanics who break plastic parts, lose bolts, and have no care for a customers car. Than a mechanic who recognizes this is beyond what they can do and try to get it to a more knowledgeable person. Of course, I understand with what Wizard is saying. I've had a car with 10 fault codes and they all seemed serious. And using my experience, I had to determine what is the root cause to all the codes. It turned out to be a loose +ve terminal and the customer wasn't closing the gas cap properly.
I helped develop that high pressure fuel pump for Stanandyne. We had very few failures of those after producing 1.5 million pumps/ year for 5 years. They operate anywhere between 80 Bar and 120 Bar (1,160-1,740 psig.)
Well I feel sorry for folks depending on dealerships with zero automotive knowledge. I had this on my 14’ 5.3 Silverado work truck. One HPFP, intermediate fuel line, one set of intake gaskets and one HPFP tool it’s now fixed. ~$200 in parts and ~3.5 hours fixed. What led me to this was two codes and overfilled crankcase. This is my newest vehicle and I will never buy anything this new again. Most folks don’t have this knowledge/info so thank you Wizard for helping many people.
I've come across several people who had to replace engines on cars less than 8 years old, my 2000 Silverado still has it's original engine. I really can't understand why people buy newer cars when older ones are much more dependable
Maybe because those cars rusted out, or had other failures, or somebody wants a newer safer vehicle. I sure as wouldn't want my kids in a 2000s vehicle driving around today
It seems that most "Repair Shops" nowadays don't know how to diagnose problems, more and more they will plump to replace a complete assembly rather than just the part that has failed. Gone are the days when a good mechanic knew how everything in a car worked and could fix it when it stopped working. I think that most of them no longer have an enquiring mind which is where you win almost every time. I am no longer able to do much work on my car but I find your videos very engaging and informative.
With today's vehicles they're over engineered and each year model there's added complications from the year before and no one can keep up with it until they encounter a problem then they gotta relearn the crap that the manufacturers don't mention. It's really not the mechanics fault it's the manufacturers who are really to blame. There are no expert mechanics anymore since all they learn is void every ten years. In 20 years maybe sooner there may not even be any mechanics willing to do it anymore or be able to, they'll have cars so screwed up the cost to repair minor crap will not even be cost effective... be disposable vehicles and completely integrated beyond fixing.
Bad shops are one of the reasons I try to do everything I can myself. One thing that really helps is, I work on a base that has a shop where military and approved civilians can work on their cars. They have lifts and all the tools necessary for almost every job. I recently did a replacement of the tie rods and ends along with an oil change.
The only time I use the stealership is to correct the recalls I get every few months. I’ve got a good local shop that doesn’t try to upsell me like the dealership. Literally every time I’ve gone in for a recall they tell me I need something else done that I take to the shop I use and my mechanic tells me it isn’t worn, broken, leaking. There’s a big problem in this country with shoddy practices at dealers.
Former GM dealer technician here, I had a pickup with this same engine that came in and ended up having a stuck open injector, and a failed hp fuel pump. That was fun sorting between fuel trims and drivability issues. To address the issue with good mechanics today (or lack there of) in my opinion there are several reasons why. 1st- starting mechanics usually have 2 options- a low hourly rate that is almost impossible to live on, or flag pay that can pay more, if you are efficient and do not run into any issues. If the mechanic is brand new they don’t have the experience to run flag pay yet, so they have to be a helper at a low hourly rate, while trying to buy tools and live. 2-old mechanics don’t like the newer generation (can’t blame them) and don’t always take them under their wing 3- the good mechanics that figure it out, usually go where the money is, or use their experience to make more in a similar field
In my experience, this is true in many industries. It's hard to find a good mechanic or contractor. I grew up on a small farm.We did all of our own repairs on tractors, cars, trucks, barns, houses, etc. Whether I'm looking to hire someone for repair work, or observing co-workers, there is plenty to be concerned about. Most do okay with average work difficulty, a few are extremely proficient, and some out there are scary.
My mother has absolutely zero interest in cars, but she can notice what her car is doing and can usually accurately describe what she's noticing. Most of the time she doesn't recognize it's a problem but just that something isn't normal. For example one day she mentioned the brake pedal feels weird at a stop light, like it's sinking or something. I immediately checked it out and found a brake line getting ready to pop. Caught it early!
The person who drives the car knows it best. I once had a brake problem where the brake pedal would occasionally sink down, but they couldn't replicate it at the garage. So one day I'm at a long stop light and it starts to sink. Aha! You have to stand on that brake for a full minute before it fails. Releasing it would just reset the "timer".
Flexi brake pipes are very forgiving. They will work normally under normal conditions. But But But It is when a child runs out in front of you and you apply extra hard pressure on the break pedal, the loyal old cracked flexi brake pipe will say Fu*k this . I cant hold the brake fluid any more and the pipe will burst. causing at least 5o^ brake failure. Modern cars have the brake system broken into 2 different circuits. That helps prevent complete brake failure.
I came across a related issue many years ago. A friend had a Honda motorcycle (from the days of carburettors ) which was doing the same thing - it ran fine until it was thoroughly warm and then it would lose power and refuse to idle. He had messed around, but no luck. Then he took it to 2 workshops, still no diagnosis. So I bought it from him at a very cheap price. Riding it home his complaint was confirmed. And it seemed to be running rich. I had a suspicion, so sniffed the dipstick - fuel. When the engine got hot the fuel would boil out and into the pcv line. Changed the needles & seats + oil and all was good. When I told the friend what I had found, he was very unhappy and demanded that I sell it back to him @ the price I paid. When I said no he was really pissed - he never spoke to me again. No problem - I don't need friends like that.
@@danwake4431 pretty much. If he had asked nicely and offered to pay me for my troubles I probably would have said yes. I think partly he was embarrassed at his failure to think logically - he was a mechanical engineer (as am i)
I have been turning wrenches for 25 years now I have my own skill set that I am good at I am ase master tech certified but I constantly watch yours and south mains videos to help me keep up to date and knowledgeable.... 25 years working on cars and still don't know 1/2 of what I need to
Me, at the beginning of the video: “That sounds like a fueling issue.” If me, someone with _zero_ experience working on cars can correctly identify that it’s a fueling issue, those shops really need to get looked at.
@KevinStull Damn right. I already knew right off the bat that it was the fuel pump going out. (The mass flow sensor would have been a good guess as well.) I figure maybe the customer was putting cheap unleaded gas (explains the bad idle, possible dirty catalytic converters, and the check engine light coming on which often happens on V8s) and running that Suburban on empty too frequently before filling it up. 🤔
I hate seeing shops and stealerships taking advantage of people for failing to do a little research. I once fixed a car that a shop could not figure out what was wrong. Initial complaint was for them to do the timing belt and the cams and crank seals because they were leaking along with diag on the Christmas lights on the dash. She is a mechanically inclined gal, but they did a parts cannon at it, tune up, coils, rewired coils, new cats, second set of new cats, fuel pump, fuel regulator, vacuum lines, fuel drain with a refill of new gas.... Plus they never touched the timing belt... $4500 later she brings it to me, check timing, intake cam off one tooth, rotate engine by hand, back in time, belt is wet with oil and is stretched. Ok, can cause the misfire and fuel problems, do the job and found a vacuum line they forgot to reconnect (easy miss). Car runs perfect in the driveway, go down the hill, start up the hill, falls flat on its face, all the Christmas lights come on, same codes set, minus the misfire codes. Clear them, run more checks, car idles great for 30 minutes, find nothing, drive the car, hit same spot does great, get to a stop sign, hit the gas... Yep Christmas tree lights, get back to the house, check codes, all different but two! Ok I have and electrical gremlin... code reader in the car on voltage reading, 13 volts, low but nothing overwhelming. Get to stop sign hit the gas, drops to 10 volts, Christmas lights again... Friggin alternator was bad!!! Slapped a new one in, solved all issues. But all those issues hid the transmission was going bad, sadly. I installed a used one a few months later and her car drives brand new!
Literally just had a 15 Yukon Denali have the exact issue besides stalling yesterday. Identifix is a lifesaver, doesn’t replace real diagnosis but a good start/direction. Watching fuel pressure (low) and fuel trims when I disconnected the pcv tube and breather tubes, fuel trims went to normal. Drained the oil (due for an oil change anyhow) smelled gassy. Had to change oil twice. Once after changing the hpfp (down to 3-12) and once 100 miles later for fuel trims to go normal. (-10 to 10)
I am a mechanic for over 51 years now and you hit the nail on the head brother. New techs are only parts replace. No proper training, there phone always in there dam hand , looking for answers, it’s pitiful 😢
It is disturbing that multiple dealerships missed this issue. I have a basic understanding of engines especially modern ones, and even I guess the fuel system during the pop quiz right off the bat. Great video Mr. Wizard! Congrats on getting to work with your wife every day. I am jealous!
Nobody ever said Dealerships.... I bet it was more like precision tune or some random "Tony's Auto" type shops. A dealer probably would have guessed it because they've came across the same issue a few times by now. Most ppl won't go to Dealers because of their high prices, which isn't exactly ture anymore, I've found parts cheaper at the dealer more than once.
I've learn to work on my 2006 GMC Sierra Classic 4.8 ltr. and my 2004 Chevy Trailblazer 4.2 ltr. 304,000 miles I6 from Car Wizard, Eric from South Main Auto, Rainman Ray Repairs and the Car Care Nut. Good folks, they know their stuff!👍 Eric, "If I can do it, you can too!"!
Fuel: Engine "dieseling" or running warm. Spark: Engine not firing up immediately, or hesitating. Air: Can be tricky on older vehicles because of vacuum lines. Newer vehicles use mass air sensors or relays that can be detected by scan tools, or some engines have a valve right over the intake that will shut after startup, killing the engine.
I am pleased to watch your video and see that there are still people like you who will take the time to figure things out. I have gone to many shops where if it doesn't jump out and bite them they can't figure out what is going on and they just guess. Thanks for taking the time and doing it right
I generally get great service from my mechanic of almost 20 years. Recently bought a '69 Cadillac. It needs a carb rebuild, points, condenser, timing, maybe plugs, etc. He told me none of his guys can work on the old stuff. Not taught in tech schools anymore. Wow! I found an old school guy at another shop and they will do the work. Great video and relevant comments. Thanks.
Glad I listened to this one, my 05 lacrosse (3.6) has been exhibiting the same symptoms. It’s not worth replacing the hp fuel pump. I just looked up the specs for that engine and it’s one of the early direct injection engines. Thanks for your explicit details.
Back in 1975 I took a pre-employment 10-month mechanics course. I was top student and when I 'graduated', I felt incompetent, but that is why there is an Apprenticeship. Later, I quit mechanics and became a shop salesman, and a couple of mechanics frequently sent vehicles out, worse than they came in? Since that time, I have tried to hire shop mechanics to repair vehicles I was not sure of, or did not have the diagnostic equipment. Nearly 80% of the time, I had to repair the repair! Smart diagnostic people do not go into the field, as they see other EASIER opportunities.
@@JasbirSingh-zj1fg Almost anything, as diagnostics requires a very analytical, mechanical and curious mind. With this level of intelligence one could be a police murder analyst.
This is exactly what was wrong with my 2013 Mercedes-Benz C250. Same symptoms. Upon hard acceleration it went into “limp home” mode. Replaced the high pressure fuel pump and it’s got great power now! I researched and diagnosed myself on the internet and the shop confirmed my suspicions.
Good job! I used to work at a VW dealer as a Tech, we had one service writer that sort of "Knew it all" he would diagnose the car at the service desk! I usually had to go out and ask what "exactly" the customer said. Because many times it was not what he put down on the work order cause he just knew what the problem was. Dont get me wrong he was a nice guy but sometimes he would send us down the garden trail... and cause much lost time. Until you got to know what he was doing and ask more questions or even call the customer your self sometimes.
@@petrosaguilar8916 Well a door rate of say $150.00 an hour ( likely so much higher now) , in a busy flat rate shop one tech is making the company/shop say min of 10 hours which is $ 1500.00 to 20 hours which is $ 3000.00 a day, times that by say 10 techs.... up to $30,000 a day just from shop labor. plus the parts mark up ( big money on some items )of course not all techs make the big hours for sure. better to pay a service writer 15 to 20 bucks an hour because most of what they do is pretty straight forward , cept for a few jobs here and there. i have done both jobs before at a different shop, you lose a lot of potential labor time on crap a non tech can do easily with a bit of training.
@@petrosaguilar8916 The mechanic is more valuable to the business....doing mechanic's work. But if you go to a one man shop you always talk to the one man.....
Brother’s, Formerly Uncle’s, 86 Suburban 4 WD with the 350cid motor still running strong at nearly 300K. Frequent oil changes, overhauled AC (new compressor and dryer, new seals, evacuate system), one rear axle seal LR side. Now pulling horse trailers easily and happily. Paint is faded and gone but mechanically rock solid.
The high pressure lines are supposed to be replaced at the time of replacement of the pump as well. Also check for any shavings from the pump that may be in the gas supply lines that can clog the fuel injectors. Mine sent me all the way down the garden path so ask me how I know...
So, now you that you have replaced the high pressure pump and the high pressure lines , the next step is to pull out the fuel injectors and send them to Dr. Injector. 😆🤑🤗
Scanner Danner did a comprehensive video on these issues. I did not find it before it happened to mine unfortunately. I also had the Bosch pump in my tank fail shortly after the high pressure pump.
Jump to 6:58 and miss the commercial and vehicle description. Good job diagnosing this problem. I did see a crankcase explode. In 1972 I was watching a mechanic trying to start a Ford 390 in a 67 F100. They had the intake off because the rear gasket would fail and leak oil. There was lots of cranking, lots of timing adjustments...then Pow crankcase explodes... both valve covers blew off
I went to the Railroad back in 06 because of the way I and my family were treated by the industry of auto maintenance. Couldn't afford health insurance, couldn't get a decent rate on loan outside of a car loan ect. As soon as I went to the rail industry I could take care of my family much better and easier.
@@ericbrenner690 It's a possible explanation of why the car repair industries can't attract people to work in it. Poor pay is No.1 on the list. Poor benefits. Bad bosses Stress from bad customers Seeing the results of stupidity every day... All relevant to an engine that requires an intake manifold removal where Japanese vehicles mostly have it on the outside of the cam covers...easily accessible. Perhaps a drive extension and a hole right through the intake manifold to make the HPFP fit outside the lifter valley might have been a good idea?
I have 2015 Equinox. A couple years ago I drove my mother to visit family out west. So from Chicago too northern Idaho than across from Seatle and then down to Portland. I kept checking the oil and it was never down. In fact, it was up. I got home and did some research on an Equinox forum and guess what I found. Lucky for me my high pressure pump is front and center. Like wizard said it was dripping gas. The oil had a real strong gas smell. How is it a retired electrician can figure this out and the guy how should know can't.
After a while, mechanics can tell you that a certain year, make and model will characteristically have a certain problem. That's what allows the KVI 570 Auto Guy to fix cars on the radio 📻
@@jamesburns2232 I call those "quirks". When I was a copier technician, once the customer start to explain what the problem was and I knew what the copier they had, I would know the problem is by the time they end the first sentence.
This sort of reminds me of some of the cars that I messed with in my younger days ( read teenage years, I'm now 73 years old) that had a mechanical fuel pump that bolted to the side of the engine that had a hole that let the pump be driven by a lobe on the camshaft. One such engine that comes to mind was the straight 6 144 CID that I had in my Ford Falcon. If the diaphragm in the pump failed it would allow gas to get into the crankcase. Still working on cars for enjoyment and exercise to keep my old butt moving ( restoring my 1996 Dodge gen 2) I really enjoy your videos for fun and information.
I had the engine in my 2017 Sonata replaced thanks to a company who did my oil change not tightening my drain plug and I got it back later than anticipated because the shop was running tests and noticed that it wasn't running right and thought it was the high pressure fuel pump. It turned out they forgot to transfer a part from the old engine. It's a good thing too, because the new pump was $1100 and probably wouldn't have been covered by the insurance company.
we had one of these with the same issue not long ago, it was quite an easy diagnosis using the exact same method you talked about. Hard to believe 3 other shops couldnt figure this out.
I think with the number of Suburbans on the road that this is more of a PSA to owners... It's not a hard repair....if you know what needs to be repaired.
Diagnostic is the most powerful tool at any shop. A decade ago i had a FERRARI F355 came in and been with almost 10 mechanics. I listened i smelled. I knew it was the fuel regulator. Before that i saw a CHEVY 454 with the FR was in the intake. Running super rich
I totally agree with the wizard. It is VERY difficult to find a competent mechanic. I found a fantastic mechanic on Craigslist that had an ad saying... If you are this type of customer (with many examples), go somewhere else. I had to meet the guy. Like the wizard, he is bald and has a long beard. He is methodical, smart, and has fair pricing. At this point, when I have a car issue, i explain what I want and he takes the time to dig into it. As a one man shop, it sometimes takes a few weeks to get car back, but the cars always work great. Good luck finding your own Wizard....P.S. There are none at the dealerships or national/regional repair chains.
Gotta love watching this channel, finding out the diagnostic path and explaining why it makes the symptoms happen and how to look out for them. Great stuff wizard! Love learning from your experience!
Real mechanic work is basically detective work. You have clues, experience, and the internet to figure it out as quickly and affordably as possible. And I love how the Wizard also explains in the common Enghlish what and why sth is happening. I just don't dig the fact that they show the personal items in the car when it's not really relevant
the access to knowledge is super important and i have found that a lot of shops do not want to do this as it costs money so they will just guess and throw parts at the wall to see what sticks and it’s even worse than that because you could have probably just googled the issues and with some knowledgeable poking found the problem it’s really unfortunate so i thank you for being the example of what a good mechanic is and what we as customers should do to make ourselves much more informed about our transportation so people don’t get taken advantage of
When i was at the dealers, the manufacturers cut the labor times by 30%. Pretty much across the board. Now instead of paying someone the time it takes to properly diagnosed something, the hired help wants to shotgun a part at it. There's usually one or two old dudes that know what they are doing in a shop. The new kids don't have a clue. If a problem vehicle gets dispatched to said kid, good luck getting it fixed. All they want to do is parts toss. The manufacturers started this mess, and the dealers don't care.
90 % of car manufacturers earnings are made from selling car parts, not from selling cars. So a very logical action to raise earnings and make stock holders happy....
Thankyou Wizard, being married I have learned especially from my wife who was a chemical lab tech for 38 years to listen closely. She pays attention to details down to the nanogram. LOL I learn something all the time from you especially on which vehicle s to avoid. I avoid turbos have 2 pathfinders. one a 2010 rear wheel drive 4 liter and the best rig I ever owned. the wife has a 2019 Pathfinder which has never had one issue. We changed the tranny oil every 25K on that one (the dealership does not me) and change the oil every 5 k with the Nissan dealership. I left GM twice once in the 1980 's then again a few years ago when the Buick Enclave bought almost new darn near put us into bankruptsy. Love yourchannel
@@AltGrendel correct. Just saying it is enough. It’s also true on the Internet of things whatever that is. It’s also true on the moon Internet, which I just made up, but maybe I didn’t. Maybe I’m an expert.
We have the same issue here in South Florida. Shops are trying to sell quick and easy jobs like $1000 brake job or selling struts or tires. But when it comes to diagnostic, not many good techs here. I have also been a master tech for the last 36 years. In all those years, i was not able to fix only one car..........dodge durango recently. Gave up on that after spending 6 hours.
great case solution. I'm having problems sorting out my 04 V6 Camry with bad knock sensors. replaced them, but the codes got back right after. the replacement parts are just junk. going to the 2nd pair now to try to solve the issue. I am a certified auto technician, but don't work in auto repair and don't have where to work in my car, so have to rely on a shop to work with me. At least I found one who's main mechanic is with me into getting my car fixed and not ripping money out of me.
I almost didn't click but I am glad I did. What a weird little issue. Glad to have the knowledge now. Mr. And Mrs. Wizard are a great team. Hope all is well.
A good mechanic will never brag because you can get humbled really quickly when you think you've seen everything... You're 100% right on the patches aslo. Some of the smartest gifted mechanics I've worked with literally could barely read. And some of the wost had ASE Master patches. They can be decent if the issues stay within written troubleshooting procedures. Anything outside what's written, they can't troubleshoot a flat tire.
I remember when a friend of mines was trying to get a job at a Yamaha motorcycle shop. He thought he was very knowledgeable about two stroke engines. The owner asked him during the interview if he knows anything about two stroke engines. My friend bragged he knew everything about two strokes. That didn't go over well with the owner. He said he's been working on them for 30 plus years and he still learns something new at times.
7:20 "he typed that information into identifix ... it said the HPFP could be failing.... it gave a test ... disconnect PCV... if went fuel trim is back to normal, then 99% it is a bad HPFP." Sooo, ok thanks identifix???
As a disclaimer I am not a mechanic, so this is a wild guess. Computer proficiency and/or the ability to use multiple technical database might be a contributing factor. Cars have gotten complicated, and a lot more different avenues of info gathering are required. Some people might really struggle with some modern cars. They might also be trying to not spend money on diagnostic tools / databases, so they are lacking critical info for some cars that they are seeing.
I can’t believe the crack in that windscreen!! Over here in the UK a vehicle fails it’s MoT test ( Compulsory Annual safety test for all vehicles 3yrs and over) for a tiny chip in the windscreen if it is within the drivers field of vision. Yet another great video Wizard.
When you made your challenge at the beginning, I was going to bet on a bad MAF or MAP sensor... Thanks for reminding me about the newer direct-injection systems.!
Wizard, I'm a IT guy by trade, work on my own cars and once in a while on family/friends cars as well. When I first started doing computer repair I thought I was hot shit because I knew how to build pc's and take apart laptops at 8 years old. I quickly realized that, no I don't know everything, in fact I didn't know much at all! I been doing IT since 2011 and I'm still learning. Same thing with the cars. I learned to build engines, troubleshoot issues (I was poor, taking it somewhere wasn't an option) and improvised when replacements parts were no longer available. Could I of figured out the issue on that SUV? Maybe. I usually wrench on older stuff. I did fix things that local dealers/shops couldn't figure out (or didn't care to) for family and friends, that's always a nice feeling.
I remember a little while back. You said you weren't going to work out anymore. Domestics except for Tyler's hooptys . But when all other shops can't fix a domestic vehicle, you got to go to the best
Every time Wizard gets flummoxed, he says he won't be doing that kind of repair anymore. It's like the airline pilot who starts out saying, I can't believe they are actually paying me to do this, I would do it for free! Then he gets greedy and says: " They had better pay me to do this, they owe me big time!" 👨✈
@@jamesburns2232 The flummoxing usually comes down to crap replacement parts. crap non-available replacement parts or no replacement parts being available for very "young" USA made vehicles....
Just in my experience, those high pressure fuel pumps weren't common to fail. My guess is that someone did the lifters which that is very common on 5.3L-6.2L but they didn't replace the seal on the high pressure fuel pump plunger. which is in the Repair Instructions. But I've seen weirder. Good find Daniel-san and great knowledge to keep in the back of my mind.
A lil' late here, but I have two GM Saabs. My 9-3 was sitting for a few years before I put it back on the road, so when I found a 9-5 that had also been sitting, I had an idea of what it would take. As a result, I'm familiar w/fuel system issues, among other things, but since I'm not a trained mechanic, I might jump to conclusions. While I can't do my own work, though, I do learn w/age and experience, and I listen and look to those who know. Thanks, Wizard.
You do not have to a "certified" mechanic to fix almost anything today. Just search the issue on UA-cam/Google and you will have many options to help fix it.
It’s nice to see someone so passionate about being a great mechanic and helping customers out.. when I find one I tell everyone I know and iam loyal to them
I’m thinking they say they can’t fix it because they don’t want to waste time on it. For the time it takes to diagnose and fix that, they could probably have three easy fixes go through the shop. Shops are busy as more people are keeping cars longer and it’s just more convenient to push this kind of work off to another shop.
I think cars are just getting more and more complex and many mechanics aren’t keeping up with that. Sounds like that service you guys use is worth its weight in gold. Kudos!
So I don't like working on any engines after 02. I still figured it out from what she said and the original 3 basic things needed for the engine. It did not sound like a cam timing issue. So if I an old guy that wouldn't touch it could halfway figure it out what's wrong with people that have been to classes on this stuff?
Totally get it I have a beautiful low miles 1990 Astro 4.3 that sat for many years and it needed a fuel pump took it to two garages and neither wanted to work on it and some just told me it's too old we don't service cars that old because we aren't trained to
You must be referring to Tow Truck Dustin in TX. GM introduced this GDI (Gas Direct Injection) in 2014 on the Gen V LT that replaced the venerable LS engine.. They require, as explained in the vid, the HPFP (High Pressure Fuel Pump) and it is failure prone.
Done a few high pressure pumps on these, so looking forward to seeing if that lines up on this one. Also fuel soaks the oil and causes rich trim codes from literally dripping fuel into the crank case.
Thank you 🙏 I learned something new today, thought I new all about GM gas V8'S like the older 5.3 , 4.8 the " LS STYLE V8'S" I couldn't make enough money mechanicing full Time , so I do it on the side, i get a lot of my work from other shops were not able to fix .
HOW the hell can a reputable shop not be able to fix the problem WIZARD ?? This is hard to believe for sure SIR. Just love your method of logical tracing of the problems. I tip my hat to your too. vf
I am a first time viewer. I almost left when the lady started showing the interior. That part was not about repairs. But I stayed, and the video finally got to the real issues. You did an excellent job explaining your diagnosis.
Hey I’ve been wrenching a long time. You’re right some of these guys call themselves mechanics shouldn’t be. You just don’t take a mechanic course and be a mechanic in 12 months. It starts when young in the garage helping your father on oil change then goes from there. Back then we didn’t have scanners and computer diagnostics. You learned from experience. You need to know basic properties of mechanics where it all starts. Nice work . By the way i automatically thought fuel pump.
I think I'm done with GM, it's inexcusable. 400 psi and failing. Meanwhile Detroits are running 29,000 PSI and it's rare they fail, my truck has 800k miles on it, no issues. Bought it new, it's my 3rd one. As far as my car, I got rid of my newer 3.0 CONTI, and bought an old Town Car. I just don't have the patience for unreliable garbage.
You're missing entirely the point of the video. It's not about that some part failed, something is always going to fail, it's about incompetent and possibly sexist mechanics unable to diagnose an issue.
Wizard is the best..As a DIY Mechanic(No expert for sure.. just learning everyday) i thought;, Air, fuel or poss DPF(EGR), but when you mentioned Fuel trims and you offered options.. I thought fuel or fuel related)… Not a bad guess for a student of my car for two years (just bought a scan tool so on my way(but want to be a diagnostic person, not a parts changer.. thanks
Wizard I had a customer bring me their Bmw 5 series this week with a complaint of the AC blower motor not operating, he told me it had been up at the BMW dealership for almost 6 months and they could never figure out why it wouldn’t blow and that he needed to replace this and that culminating in about $6000. And I know Bmw is and I know where the blower motor is and how it operates, etc. so I told him to bring it from the dealer to my shop , he dropped it off. I told him I would look at it later in the day., I had barely had the cow off the windshield for five minutes when I saw the blower motor resistor just sitting there unplugged, for shits and giggles I plugged the resistor back in and tested the car, and I’ll be a son of a bitch if the blower motor did not come on and the AC was working as it should, The blower motor resistor connector sits right under the windshield cowl on the right hand side, and any even halfway competent mechanic should’ve been able to look under that Cowell if the blower motor was diagnosed faulty as they said it was they even said they even had it out on a workbench and bench tested it, I called the customer and let him know the good news and he was pretty upset. He almost didn’t even believe me until he picked up the car., and this car was at a very reputable BMW dealership in Atlanta I just was blown away
We just had a local mechanic retire and sell his building to a younger, eager guy who freshened up the place and started another garage. The only tech he could hire is a 63 year old guy. Nobody wants to work, we are too comfy as a species. Less and less go into trades as well. It's a bummer.
Doubt that, it's called being paid a livable and decent wage. A young mechanic can't afford minimum wage or the equivalent with the current cost of living, especially rent.
"Everybody is a mechanic" but very, very few have went through trade school, have a professional set of tools, and the years of accumulated experience to back that statement up!
Because the capitalist model rewards shrewdness and greed not skill unless you're a doctor. I've said it before, somebody like Grimes and Magic Mike should be earning at least $100k/yr working for somebody else.

Anyone can turn a wrench and change parts. It takes a good mechanic to know how to diagnose an issue.

A good and honest mechanic is worth their weight in gold. And unfortunately, my trusted mechanic/shop owner and friend of 35 years recently passed away. He was another one of those gurus who was able to fix what other shops couldn't or wouldn't. Gas, diesel, EVs, hybrids... cars, trucks, large trucks, semis and even small aircraft. Engine and tranny rebuilds too. No job was too small or two big. He was the best with certifications out his butt.
A good friend is impossible to replace.... a good mechanic is almost as hard.
Well said. These men are a dying breed. About as precious as gold.

I spent 45 years as a licensed aircraft mechanic. I was still learning stuff up until the day I retired.
I think the answer to your question about why it's hard to find good mechanics is in how Daniel-San worked this problem. Before anything, he needed to find a fault that fit all the symptoms AND with his overall knowledge. The big negative fuel trim numbers were key because it leads to the question: "Where is all that extra fuel coming from?" Knowing that the ECU was cutting fuel to the injectors, he's left with the only remaining source: the PCV system. He also knows from the Internet that the HP pump can leak fuel into the crankcase. Finally, he asks: "Does this explain everything the customer reported?" The answer is "yes" and he knows what to do.
This methodical approach takes longer and requires deeper understanding. It's a lot easier and faster to do a couple of searches and imitate. If you don't really understand how things work, imitation is about all you can do. If the search uncovers multiple options and you don't know which one is right, you can either guess and risk fixing the wrong thing or you can punt. Those other two shops punted.
To be a really good mechanic, I think you need a solid understanding of how cars work and the discipline to find faults that explain everything you're seeing.
Problem is shops could. But spending so much time chasing diagnostics is a good way to go out of business. How long and how much work to deduce this? Imagine getting a bill for several hours of diagnostics.
Only reason Wizard found it is because somebody else took the hit.
'We cant figure it out' is another way of saying 'we dont want to fix this problem'
Also reflects the ability to adapt to change and employ new tools like databases that help diagnose problems.
@@russelljacob7955- The root cause of what you describe is the mechanics are not really mechanics. They are code readers & have no clue what to do with the information they find. That falls on the shop management, in not training their people to learn what to do with the valuable data they acquire.
@@cmdrdarwin3682 Is it? Is just knowledge. How long would it take any of us without having worked on the vehicle prior to have come to this determination? Yeah, is simple to state after the fact. How long to get to that determination? Then verifying too.
After a few hours, one might be able to determine that fuel is getting in crankcase. Then what? Testing and checking all cylinders because assume maybe an injector issue or what?
Whomever figured it out the first time was somebody who has ripped apart an engine. Perhaps in parts cannon to solve the issue. How many would even think that fuel pump sealed to crankcase.
I cite an example of my own personal car from years ago. Brakes felt off. Weak and mushy.
Cause? Cause was a leak where intake manifold sealed to block on a GM 3.1 v6.
I really dislike wizard for the assertions he was making. The only thing other shops did wrong was not having that database wizard did and not wanting to take on the liability.
Wizard has said it himself about things he wont do, wont touch. Does that make him a bad mechanic?
@@russelljacob7955 I agree with what you're saying. I'm a mobile mechanic and I have across cars where I've fixed issues that other shops could not fix. But I've also been in a situation where I couldn't fix a problem a customer was having. I could have spend hour wasting the customer time and money, or be honest (which they really appreciate) and tell the customer I've exhausted all my resources and cannot fix the issue. Does that make me a bad mechanic? I don't think it does.
I'm more worried about gorilla mechanics who break plastic parts, lose bolts, and have no care for a customers car. Than a mechanic who recognizes this is beyond what they can do and try to get it to a more knowledgeable person.
Of course, I understand with what Wizard is saying. I've had a car with 10 fault codes and they all seemed serious. And using my experience, I had to determine what is the root cause to all the codes. It turned out to be a loose +ve terminal and the customer wasn't closing the gas cap properly.
I helped develop that high pressure fuel pump for Stanandyne. We had very few failures of those after producing 1.5 million pumps/ year for 5 years. They operate anywhere between 80 Bar and 120 Bar (1,160-1,740 psig.)
Well I feel sorry for folks depending on dealerships with zero automotive knowledge. I had this on my 14’ 5.3 Silverado work truck. One HPFP, intermediate fuel line, one set of intake gaskets and one HPFP tool it’s now fixed. ~$200 in parts and ~3.5 hours fixed. What led me to this was two codes and overfilled crankcase. This is my newest vehicle and I will never buy anything this new again. Most folks don’t have this knowledge/info so thank you Wizard for helping many people.
You should have made a video of it. Need all the help I can get because I'm waiting for either this or the AFM to fail on my '16 Silverado....
I've come across several people who had to replace engines on cars less than 8 years old, my 2000 Silverado still has it's original engine. I really can't understand why people buy newer cars when older ones are much more dependable
2000 Suburban has one of the top 10 greatest engines ever made. This newer Suburban has a not so great engine.
Obviously they dont make cars like they used to unless you talking about toyota lexus honda
Maybe because those cars rusted out, or had other failures, or somebody wants a newer safer vehicle. I sure as wouldn't want my kids in a 2000s vehicle driving around today
Bro the 5.3 vortec is a beastly simple and well designed engine
@@burntnougat5341 what cars did that engine come in and what transmission did they match this engine with ?
It seems that most "Repair Shops" nowadays don't know how to diagnose problems, more and more they will plump to replace a complete assembly rather than just the part that has failed. Gone are the days when a good mechanic knew how everything in a car worked and could fix it when it stopped working. I think that most of them no longer have an enquiring mind which is where you win almost every time. I am no longer able to do much work on my car but I find your videos very engaging and informative.
A lot of that is the manufactures fault as well
With today's vehicles they're over engineered and each year model there's added complications from the year before and no one can keep up with it until they encounter a problem then they gotta relearn the crap that the manufacturers don't mention. It's really not the mechanics fault it's the manufacturers who are really to blame. There are no expert mechanics anymore since all they learn is void every ten years. In 20 years maybe sooner there may not even be any mechanics willing to do it anymore or be able to, they'll have cars so screwed up the cost to repair minor crap will not even be cost effective... be disposable vehicles and completely integrated beyond fixing.
Bad shops are one of the reasons I try to do everything I can myself. One thing that really helps is, I work on a base that has a shop where military and approved civilians can work on their cars. They have lifts and all the tools necessary for almost every job. I recently did a replacement of the tie rods and ends along with an oil change.
I did my first turbo car build at one of those. lol
The only time I use the stealership is to correct the recalls I get every few months. I’ve got a good local shop that doesn’t try to upsell me like the dealership. Literally every time I’ve gone in for a recall they tell me I need something else done that I take to the shop I use and my mechanic tells me it isn’t worn, broken, leaking. There’s a big problem in this country with shoddy practices at dealers.
Former GM dealer technician here, I had a pickup with this same engine that came in and ended up having a stuck open injector, and a failed hp fuel pump. That was fun sorting between fuel trims and drivability issues.
To address the issue with good mechanics today (or lack there of) in my opinion there are several reasons why.
1st- starting mechanics usually have 2 options- a low hourly rate that is almost impossible to live on, or flag pay that can pay more, if you are efficient and do not run into any issues. If the mechanic is brand new they don’t have the experience to run flag pay yet, so they have to be a helper at a low hourly rate, while trying to buy tools and live.
2-old mechanics don’t like the newer generation (can’t blame them) and don’t always take them under their wing
3- the good mechanics that figure it out, usually go where the money is, or use their experience to make more in a similar field
I had a stuck open injector on a BMW with less than 60k miles
In my experience, this is true in many industries. It's hard to find a good mechanic or contractor. I grew up on a small farm.We did all of our own repairs on tractors, cars, trucks, barns, houses, etc. Whether I'm looking to hire someone for repair work, or observing co-workers, there is plenty to be concerned about. Most do okay with average work difficulty, a few are extremely proficient, and some out there are scary.
My mother has absolutely zero interest in cars, but she can notice what her car is doing and can usually accurately describe what she's noticing. Most of the time she doesn't recognize it's a problem but just that something isn't normal. For example one day she mentioned the brake pedal feels weird at a stop light, like it's sinking or something. I immediately checked it out and found a brake line getting ready to pop. Caught it early!
The person who drives the car knows it best. I once had a brake problem where the brake pedal would occasionally sink down, but they couldn't replicate it at the garage. So one day I'm at a long stop light and it starts to sink. Aha! You have to stand on that brake for a full minute before it fails. Releasing it would just reset the "timer".
I agree. I notice that Women have more acute senses. Maybe evolution advantage?
Flexi brake pipes are very forgiving. They will work normally under normal conditions.
But But But
It is when a child runs out in front of you and you apply extra hard pressure on the break pedal, the loyal old cracked flexi brake pipe will say Fu*k this . I cant hold the brake fluid any more and the pipe will burst. causing at least 5o^ brake failure.
Modern cars have the brake system broken into 2 different circuits.
That helps prevent complete brake failure.
The female is the more intelligent of the sexes.
they think and then act.
Men tend to act and then think.
I came across a related issue many years ago.
A friend had a Honda motorcycle (from the days of carburettors ) which was doing the same thing - it ran fine until it was thoroughly warm and then it would lose power and refuse to idle.
He had messed around, but no luck. Then he took it to 2 workshops, still no diagnosis.
So I bought it from him at a very cheap price. Riding it home his complaint was confirmed. And it seemed to be running rich.
I had a suspicion, so sniffed the dipstick - fuel.
When the engine got hot the fuel would boil out and into the pcv line.
Changed the needles & seats + oil and all was good.
When I told the friend what I had found, he was very unhappy and demanded that I sell it back to him @ the price I paid.
When I said no he was really pissed - he never spoke to me again. No problem - I don't need friends like that.
hahaha, was that a VTR 1000/ Firestorm by chance?
@@ghostrider-be9ek no it wasn't that, but a lot of the Japanese bikes of that era used the same crappy carbs.
so he just wanted a free repair? no offer to pay for the fix??
@@danwake4431 pretty much. If he had asked nicely and offered to pay me for my troubles I probably would have said yes.
I think partly he was embarrassed at his failure to think logically - he was a mechanical engineer (as am i)
No need to rub it in.

Good attitude to have. You are never done learning with automobiles. Keep up the good work
Car Wizard (OMEGA CAR CLINIC) and South Main Auto are BEASTS when it comes to diagnosing these issues. Love both these channels.
Me, at the beginning of the video: “That sounds like a fueling issue.”
If me, someone with _zero_ experience working on cars can correctly identify that it’s a fueling issue, those shops really need to get looked at.
Yeah, before the three choices were shown, I thought 'it's randomly stalling, random lack of power, almost dieseling on shutdown...maybe the HPFP'.
Haha for real. The minute he gave the three choices, I was like “has to be fuel.” Again, barely any knowledge on car repair.
LOL! You took my comment!
@KevinStull Damn right. I already knew right off the bat that it was the fuel pump going out. (The mass flow sensor would have been a good guess as well.) I figure maybe the customer was putting cheap unleaded gas (explains the bad idle, possible dirty catalytic converters, and the check engine light coming on which often happens on V8s) and running that Suburban on empty too frequently before filling it up. 🤔
I hate seeing shops and stealerships taking advantage of people for failing to do a little research. I once fixed a car that a shop could not figure out what was wrong. Initial complaint was for them to do the timing belt and the cams and crank seals because they were leaking along with diag on the Christmas lights on the dash. She is a mechanically inclined gal, but they did a parts cannon at it, tune up, coils, rewired coils, new cats, second set of new cats, fuel pump, fuel regulator, vacuum lines, fuel drain with a refill of new gas.... Plus they never touched the timing belt... $4500 later she brings it to me, check timing, intake cam off one tooth, rotate engine by hand, back in time, belt is wet with oil and is stretched. Ok, can cause the misfire and fuel problems, do the job and found a vacuum line they forgot to reconnect (easy miss). Car runs perfect in the driveway, go down the hill, start up the hill, falls flat on its face, all the Christmas lights come on, same codes set, minus the misfire codes. Clear them, run more checks, car idles great for 30 minutes, find nothing, drive the car, hit same spot does great, get to a stop sign, hit the gas... Yep Christmas tree lights, get back to the house, check codes, all different but two! Ok I have and electrical gremlin... code reader in the car on voltage reading, 13 volts, low but nothing overwhelming. Get to stop sign hit the gas, drops to 10 volts, Christmas lights again... Friggin alternator was bad!!! Slapped a new one in, solved all issues. But all those issues hid the transmission was going bad, sadly. I installed a used one a few months later and her car drives brand new!
Literally just had a 15 Yukon Denali have the exact issue besides stalling yesterday. Identifix is a lifesaver, doesn’t replace real diagnosis but a good start/direction. Watching fuel pressure (low) and fuel trims when I disconnected the pcv tube and breather tubes, fuel trims went to normal. Drained the oil (due for an oil change anyhow) smelled gassy. Had to change oil twice. Once after changing the hpfp (down to 3-12) and once 100 miles later for fuel trims to go normal. (-10 to 10)
It's not just technical training, but it takes experience and common sense to diagnose and service a vehicle property
You can gain experience, unfortunately not common sense.....
I am a mechanic for over 51 years now and you hit the nail on the head brother. New techs are only parts replace. No proper training, there phone always in there dam hand , looking for answers, it’s pitiful 😢
It is disturbing that multiple dealerships missed this issue. I have a basic understanding of engines especially modern ones, and even I guess the fuel system during the pop quiz right off the bat. Great video Mr. Wizard! Congrats on getting to work with your wife every day. I am jealous!
Nobody ever said Dealerships.... I bet it was more like precision tune or some random "Tony's Auto" type shops. A dealer probably would have guessed it because they've came across the same issue a few times by now. Most ppl won't go to Dealers because of their high prices, which isn't exactly ture anymore, I've found parts cheaper at the dealer more than once.

Fuel: Engine "dieseling" or running warm.
Spark: Engine not firing up immediately, or hesitating.
Air: Can be tricky on older vehicles because of vacuum lines. Newer vehicles use mass air sensors or relays that can be detected by scan tools, or some engines have a valve right over the intake that will shut after startup, killing the engine.
I am pleased to watch your video and see that there are still people like you who will take the time to figure things out. I have gone to many shops where if it doesn't jump out and bite them they can't figure out what is going on and they just guess. Thanks for taking the time and doing it right

I found an old school guy at another shop and they will do the work. Great video and relevant comments. Thanks.

Glad I listened to this one, my 05 lacrosse (3.6) has been exhibiting the same symptoms. It’s not worth replacing the hp fuel pump. I just looked up the specs for that engine and it’s one of the early direct injection engines. Thanks for your explicit details.
Back in 1975 I took a pre-employment 10-month mechanics course. I was top student and when I 'graduated', I felt incompetent, but that is why there is an Apprenticeship. Later, I quit mechanics and became a shop salesman, and a couple of mechanics frequently sent vehicles out, worse than they came in? Since that time, I have tried to hire shop mechanics to repair vehicles I was not sure of, or did not have the diagnostic equipment. Nearly 80% of the time, I had to repair the repair! Smart diagnostic people do not go into the field, as they see other EASIER opportunities.
What opportunities are easier than vehicle diagnostics?
@@JasbirSingh-zj1fg Almost anything, as diagnostics requires a very analytical, mechanical and curious mind. With this level of intelligence one could be a police murder analyst.

Diagnosing electronics problems in a nice clean air conditioned workshop?
This is exactly what was wrong with my 2013 Mercedes-Benz C250. Same symptoms. Upon hard acceleration it went into “limp home” mode. Replaced the high pressure fuel pump and it’s got great power now! I researched and diagnosed myself on the internet and the shop confirmed my suspicions.
Good job! I used to work at a VW dealer as a Tech, we had one service writer that sort of "Knew it all" he would diagnose the car at the service desk! I usually had to go out and ask what "exactly" the customer said. Because many times it was not what he put down on the work order cause he just knew what the problem was. Dont get me wrong he was a nice guy but sometimes he would send us down the garden trail... and cause much lost time. Until you got to know what he was doing and ask more questions or even call the customer your self sometimes.
I never understood service advisors. Cut out the middle man and speak to the mechanic directly.
@@petrosaguilar8916 Well a door rate of say $150.00 an hour ( likely so much higher now) , in a busy flat rate shop one tech is making the company/shop say min of 10 hours which is $ 1500.00 to 20 hours which is $ 3000.00 a day, times that by say 10 techs.... up to $30,000 a day just from shop labor. plus the parts mark up ( big money on some items )of course not all techs make the big hours for sure. better to pay a service writer 15 to 20 bucks an hour because most of what they do is pretty straight forward , cept for a few jobs here and there. i have done both jobs before at a different shop, you lose a lot of potential labor time on crap a non tech can do easily with a bit of training.

, the next step is to pull out the fuel injectors and send them to Dr. Injector. 😆🤑🤗
Scanner Danner did a comprehensive video on these issues. I did not find it before it happened to mine unfortunately. I also had the Bosch pump in my tank fail shortly after the high pressure pump.
ScannerDanner channel Stuck Open Fuel Injectors (GDI) Part 1 Symptoms and Troubleshooting. Second part covers what was missed the first time around.
Jump to 6:58 and miss the commercial and vehicle description. Good job diagnosing this problem. I did see a crankcase explode. In 1972 I was watching a mechanic trying to start a Ford 390 in a 67 F100. They had the intake off because the rear gasket would fail and leak oil. There was lots of cranking, lots of timing adjustments...then Pow crankcase explodes... both valve covers blew off
I went to the Railroad back in 06 because of the way I and my family were treated by the industry of auto maintenance. Couldn't afford health insurance, couldn't get a decent rate on loan outside of a car loan ect. As soon as I went to the rail industry I could take care of my family much better and easier.

What does your comment have to do with a high pressure fuel pump on a 2016 Suburban? 🤔🤔
@@ericbrenner690
It's a possible explanation of why the car repair industries can't attract people to work in it.
Poor pay is No.1 on the list.
Poor benefits.
Bad bosses
Stress from bad customers
Seeing the results of stupidity every day...
All relevant to an engine that requires an intake manifold removal where Japanese vehicles mostly have it on the outside of the cam covers...easily accessible.
Perhaps a drive extension and a hole right through the intake manifold to make the HPFP fit outside the lifter valley might have been a good idea?
Always love when the CarWizard takes a car that's been looked at by a shop or three that says they dont know or it cant be fixed.
I have 2015 Equinox. A couple years ago I drove my mother to visit family out west. So from Chicago too northern Idaho than across from Seatle and then down to Portland. I kept checking the oil and it was never down. In fact, it was up. I got home and did some research on an Equinox forum and guess what I found. Lucky for me my high pressure pump is front and center. Like wizard said it was dripping gas. The oil had a real strong gas smell. How is it a retired electrician can figure this out and the guy how should know can't.
After a while, mechanics can tell you that a certain year, make and model will characteristically have a certain problem. That's what allows the KVI 570 Auto Guy to fix cars on the radio 📻
@@jamesburns2232 I call those "quirks". When I was a copier technician, once the customer start to explain what the problem was and I knew what the copier they had, I would know the problem is by the time they end the first sentence.
This sort of reminds me of some of the cars that I messed with in my younger days ( read teenage years, I'm now 73 years old) that had a mechanical fuel pump that bolted to the side of the engine that had a hole that let the pump be driven by a lobe on the camshaft. One such engine that comes to mind was the straight 6 144 CID that I had in my Ford Falcon. If the diaphragm in the pump failed it would allow gas to get into the crankcase. Still working on cars for enjoyment and exercise to keep my old butt moving ( restoring my 1996 Dodge gen 2) I really enjoy your videos for fun and information.
I had the engine in my 2017 Sonata replaced thanks to a company who did my oil change not tightening my drain plug and I got it back later than anticipated because the shop was running tests and noticed that it wasn't running right and thought it was the high pressure fuel pump. It turned out they forgot to transfer a part from the old engine. It's a good thing too, because the new pump was $1100 and probably wouldn't have been covered by the insurance company.
we had one of these with the same issue not long ago, it was quite an easy diagnosis using the exact same method you talked about. Hard to believe 3 other shops couldnt figure this out.
Good to see Car Wizard is featuring some domestic vehicles again. GREAT VIDEO!
I think with the number of Suburbans on the road that this is more of a PSA to owners...
It's not a hard repair....if you know what needs to be repaired.
Diagnostic is the most powerful tool at any shop. A decade ago i had a FERRARI F355 came in and been with almost 10 mechanics. I listened i smelled. I knew it was the fuel regulator. Before that i saw a CHEVY 454 with the FR was in the intake. Running super rich
I totally agree with the wizard. It is VERY difficult to find a competent mechanic. I found a fantastic mechanic on Craigslist that had an ad saying... If you are this type of customer (with many examples), go somewhere else. I had to meet the guy. Like the wizard, he is bald and has a long beard. He is methodical, smart, and has fair pricing. At this point, when I have a car issue, i explain what I want and he takes the time to dig into it. As a one man shop, it sometimes takes a few weeks to get car back, but the cars always work great. Good luck finding your own Wizard....P.S. There are none at the dealerships or national/regional repair chains.
Gotta love watching this channel, finding out the diagnostic path and explaining why it makes the symptoms happen and how to look out for them. Great stuff wizard! Love learning from your experience!
Real mechanic work is basically detective work. You have clues, experience, and the internet to figure it out as quickly and affordably as possible. And I love how the Wizard also explains in the common Enghlish what and why sth is happening. I just don't dig the fact that they show the personal items in the car when it's not really relevant
the access to knowledge is super important and i have found that a lot of shops do not want to do this as it costs money so they will just guess and throw parts at the wall to see what sticks and it’s even worse than that because you could have probably just googled the issues and with some knowledgeable poking found the problem it’s really unfortunate so i thank you for being the example of what a good mechanic is and what we as customers should do to make ourselves much more informed about our transportation so people don’t get taken advantage of
In the old days esp in the '90 these cars built like tanks and they were very comfortable reliable solid with few issues .
When i was at the dealers, the manufacturers cut the labor times by 30%. Pretty much across the board. Now instead of paying someone the time it takes to properly diagnosed something, the hired help wants to shotgun a part at it.
There's usually one or two old dudes that know what they are doing in a shop. The new kids don't have a clue. If a problem vehicle gets dispatched to said kid, good luck getting it fixed.
All they want to do is parts toss. The manufacturers started this mess, and the dealers don't care.
90 % of car manufacturers earnings are made from selling car parts, not from selling cars. So a very logical action to raise earnings and make stock holders happy....
Thankyou Wizard, being married I have learned especially from my wife who was a chemical lab tech for 38 years to listen closely. She pays attention to details down to the nanogram. LOL I learn something all the time from you especially on which vehicle s to avoid. I avoid turbos have 2 pathfinders. one a 2010 rear wheel drive 4 liter and the best rig I ever owned. the wife has a 2019 Pathfinder which has never had one issue. We changed the tranny oil every 25K on that one (the dealership does not me) and change the oil every 5 k with the Nissan dealership. I left GM twice once in the 1980 's then again a few years ago when the Buick Enclave bought almost new darn near put us into bankruptsy. Love yourchannel

It probably needs an oil change. I consider myself an expert.
Muffler bearings
I consider you an expert too. It’s on the Internet so it must be true.
How did you know!
@@AltGrendel correct. Just saying it is enough. It’s also true on the Internet of things whatever that is. It’s also true on the moon Internet, which I just made up, but maybe I didn’t. Maybe I’m an expert.
Well yes, after the actual repair and all that fuel going into the crankcase.
We have the same issue here in South Florida. Shops are trying to sell quick and easy jobs like $1000 brake job or selling struts or tires. But when it comes to diagnostic, not many good techs here. I have also been a master tech for the last 36 years. In all those years, i was not able to fix only one car..........dodge durango recently. Gave up on that after spending 6 hours.
Did you access Identifix??😁
I love wizard's wisdom at the end. I would love to hear him drunk ranting ahaha
great case solution. I'm having problems sorting out my 04 V6 Camry with bad knock sensors. replaced them, but the codes got back right after. the replacement parts are just junk. going to the 2nd pair now to try to solve the issue. I am a certified auto technician, but don't work in auto repair and don't have where to work in my car, so have to rely on a shop to work with me. At least I found one who's main mechanic is with me into getting my car fixed and not ripping money out of me.
I almost didn't click but I am glad I did. What a weird little issue. Glad to have the knowledge now. Mr. And Mrs. Wizard are a great team. Hope all is well.
A good mechanic will never brag because you can get humbled really quickly when you think you've seen everything...
You're 100% right on the patches aslo. Some of the smartest gifted mechanics I've worked with literally could barely read. And some of the wost had ASE Master patches. They can be decent if the issues stay within written troubleshooting procedures. Anything outside what's written, they can't troubleshoot a flat tire.
that's a house, not a car!🤣🤣🤣🤣
‘Murica.
Or an aircraft carrier. WHAT is the reason behind such 'civilian tanks'?
Suburbans/Escalade are very useful vehicles is you have the need for one. Once you have had one it is hard to give them up.
I think my Excursion is 1.5 feet longer; you look down at those in Suburbans.
That’s a boat‼️
I remember when a friend of mines was trying to get a job at a Yamaha motorcycle shop. He thought he was very knowledgeable about two stroke engines. The owner asked him during the interview if he knows anything about two stroke engines. My friend bragged he knew everything about two strokes. That didn't go over well with the owner. He said he's been working on them for 30 plus years and he still learns something new at times.
7:20 "he typed that information into identifix ... it said the HPFP could be failing.... it gave a test ... disconnect PCV... if went fuel trim is back to normal, then 99% it is a bad HPFP." Sooo, ok thanks identifix???
Car Wizard does an excellent job at Dumbing down a complex modern engine and it’s operation for guys like me. Very educational and appreciated
As a disclaimer I am not a mechanic, so this is a wild guess. Computer proficiency and/or the ability to use multiple technical database might be a contributing factor.
Cars have gotten complicated, and a lot more different avenues of info gathering are required. Some people might really struggle with some modern cars.
They might also be trying to not spend money on diagnostic tools / databases, so they are lacking critical info for some cars that they are seeing.
they were looking to place her in a new or newer ride. Just business
I can’t believe the crack in that windscreen!! Over here in the UK a vehicle fails it’s MoT test ( Compulsory Annual safety test for all vehicles 3yrs and over) for a tiny chip in the windscreen if it is within the drivers field of vision. Yet another great video Wizard.
My car knowledge IQ goes up with every Car Wizard vid I watch, thank you car wizard. Ill point my kansas friends your way for repairs!
When you made your challenge at the beginning, I was going to bet on a bad MAF or MAP sensor... Thanks for reminding me about the newer direct-injection systems.!
I think the word you are looking for Car Wizard is - "Incompetence"
Wizard, I'm a IT guy by trade, work on my own cars and once in a while on family/friends cars as well. When I first started doing computer repair I thought I was hot shit because I knew how to build pc's and take apart laptops at 8 years old. I quickly realized that, no I don't know everything, in fact I didn't know much at all! I been doing IT since 2011 and I'm still learning.
Same thing with the cars. I learned to build engines, troubleshoot issues (I was poor, taking it somewhere wasn't an option) and improvised when replacements parts were no longer available. Could I of figured out the issue on that SUV? Maybe. I usually wrench on older stuff. I did fix things that local dealers/shops couldn't figure out (or didn't care to) for family and friends, that's always a nice feeling.
I remember a little while back. You said you weren't going to work out anymore. Domestics except for Tyler's hooptys . But when all other shops can't fix a domestic vehicle, you got to go to the best
Every time Wizard gets flummoxed, he says he won't be doing that kind of repair anymore. It's like the airline pilot who starts out saying, I can't believe they are actually paying me to do this, I would do it for free! Then he gets greedy and says: " They had better pay me to do this, they owe me big time!" 👨✈
@@jamesburns2232
The flummoxing usually comes down to crap replacement parts.
crap non-available replacement parts
or no replacement parts being available for very "young" USA made vehicles....
Just in my experience, those high pressure fuel pumps weren't common to fail. My guess is that someone did the lifters which that is very common on 5.3L-6.2L but they didn't replace the seal on the high pressure fuel pump plunger. which is in the Repair Instructions. But I've seen weirder. Good find Daniel-san and great knowledge to keep in the back of my mind.
No excuse for not finding this problem. I guessed a bad fuel pump in the first 30 seconds, and I’m just an occasional home diy-er.
Yeah but, _which_ fuel pump?
20/20 hindsight is great isn't it!
Sure ya did lmaooo
You guessed a bad fuel pump without the proper information. That's not the same as "finding" the problem.
A lil' late here, but I have two GM Saabs. My 9-3 was sitting for a few years before I put it back on the road, so when I found a 9-5 that had also been sitting, I had an idea of what it would take. As a result, I'm familiar w/fuel system issues, among other things, but since I'm not a trained mechanic, I might jump to conclusions. While I can't do my own work, though, I do learn w/age and experience, and I listen and look to those who know. Thanks, Wizard.
Wow. Those 3 other shops must not have “the intrawebs” as the diagnostic and solution was KNOWN!
"2 or 3"
I just fixed a car 100 shops could not fix, true story.
You do not have to a "certified" mechanic to fix almost anything today. Just search the issue on UA-cam/Google and you will have many options to help fix it.
it's a 2016. They wanted to sell her a shiny new-ish 2022.
Not a cheap fuel pump.
It’s nice to see someone so passionate about being a great mechanic and helping customers out.. when I find one I tell everyone I know and iam loyal to them
I’m thinking they say they can’t fix it because they don’t want to waste time on it. For the time it takes to diagnose and fix that, they could probably have three easy fixes go through the shop. Shops are busy as more people are keeping cars longer and it’s just more convenient to push this kind of work off to another shop.
Well put and very true
I think cars are just getting more and more complex and many mechanics aren’t keeping up with that. Sounds like that service you guys use is worth its weight in gold. Kudos!
I looked at goodchop, 14 items for $269 seemed rather expensive
Just canceled with them. Majority of the products were freezer burnt and pretty bad quality once thawed to cook.
And it makes you wonder how big a serving is ;-)
So I don't like working on any engines after 02. I still figured it out from what she said and the original 3 basic things needed for the engine. It did not sound like a cam timing issue. So if I an old guy that wouldn't touch it could halfway figure it out what's wrong with people that have been to classes on this stuff?
Does anyone else notice Mrs wizard gasping for air in between words during the interior review. Its every video 😂 love them both tho 😊
Totally get it I have a beautiful low miles 1990 Astro 4.3 that sat for many years and it needed a fuel pump took it to two garages and neither wanted to work on it and some just told me it's too old we don't service cars that old because we aren't trained to
I watch a tow truck channel and he said he is always picking up newer GM trucks and SUVs with bad fuel pump systems
You must be referring to Tow Truck Dustin in TX. GM introduced this GDI (Gas Direct Injection) in 2014 on the Gen V LT that replaced the venerable LS engine.. They require, as explained in the vid, the HPFP (High Pressure Fuel Pump) and it is failure prone.
@@guyintenn Yep he has a good channel
Done a few high pressure pumps on these, so looking forward to seeing if that lines up on this one.
Also fuel soaks the oil and causes rich trim codes from literally dripping fuel into the crank case.
Diagnose Dan in The Netherlands posted a video of exactly this issue on a VW Golf about four years ago.
Thank you 🙏 I learned something new today, thought I new all about GM gas V8'S like the older 5.3 , 4.8 the " LS STYLE V8'S" I couldn't make enough money mechanicing full Time , so I do it on the side, i get a lot of my work from other shops were not able to fix .
Stand alone direct fuel injection improves combustion efficiency but may also eventually mess up engines in newer, much more expensive, ways.
HOW the hell can a reputable shop not be able to fix the problem WIZARD ?? This is hard to believe for sure SIR. Just love your method of logical tracing of the problems. I tip my hat to your too. vf
I am a first time viewer. I almost left when the lady started showing the interior. That part was not about repairs. But I stayed, and the video finally got to the real issues. You did an excellent job explaining your diagnosis.
They always check out the whole vehicle
Do you want honest feedback. The wife giving a "The Price is Right" tour of every vehicle is an annoyance. It will cost you viewers.
Hey I’ve been wrenching a long time. You’re right some of these guys call themselves mechanics shouldn’t be. You just don’t take a mechanic course and be a mechanic in 12 months. It starts when young in the garage helping your father on oil change then goes from there. Back then we didn’t have scanners and computer diagnostics. You learned from experience. You need to know basic properties of mechanics where it all starts. Nice work . By the way i automatically thought fuel pump.
I think I'm done with GM, it's inexcusable. 400 psi and failing. Meanwhile Detroits are running 29,000 PSI and it's rare they fail, my truck has 800k miles on it, no issues. Bought it new, it's my 3rd one. As far as my car, I got rid of my newer 3.0 CONTI, and bought an old Town Car. I just don't have the patience for unreliable garbage.
You're missing entirely the point of the video. It's not about that some part failed, something is always going to fail, it's about incompetent and possibly sexist mechanics unable to diagnose an issue.
Sexist? 😃 Go hide under mama's skirt.
@HydraulicDesign he has a point, and you brought up sexism for some reason. These components are garbage
@@rafmatt1607 I see that you didn't watch the video. Also what points were made, the complete non-sequitur that heavy-duty diesel pumps "rarely" fail?

@@kevinbarry71 I think that 5.4 might be the worst engine out there
@@WayneKerr69420 it's up there. But it's still ahead of a lot of German engines
Wizard is the best..As a DIY Mechanic(No expert for sure.. just learning everyday) i thought;, Air, fuel or poss DPF(EGR), but when you mentioned Fuel trims and you offered options.. I thought fuel or fuel related)… Not a bad guess for a student of my car for two years (just bought a scan tool so on my way(but want to be a diagnostic person, not a parts changer.. thanks
I forgot where I saw this from, but when you see GDI, it doesn’t stand for gasoline direct injection, it stands for god damn it
Such a premium video! All or your videos are outstanding! You are among the most adept mechanics out there. Mrs. Wizard adds a great touch too.
Wizard I had a customer bring me their Bmw 5 series this week with a complaint of the AC blower motor not operating, he told me it had been up at the BMW dealership for almost 6 months and they could never figure out why it wouldn’t blow and that he needed to replace this and that culminating in about $6000.
And I know Bmw is and I know where the blower motor is and how it operates, etc. so I told him to bring it from the dealer to my shop , he dropped it off. I told him I would look at it later in the day., I had barely had the cow off the windshield for five minutes when I saw the blower motor resistor just sitting there unplugged, for shits and giggles I plugged the resistor back in and tested the car, and I’ll be a son of a bitch if the blower motor did not come on and the AC was working as it should, The blower motor resistor connector sits right under the windshield cowl on the right hand side, and any even halfway competent mechanic should’ve been able to look under that Cowell if the blower motor was diagnosed faulty as they said it was they even said they even had it out on a workbench and bench tested it, I called the customer and let him know the good news and he was pretty upset. He almost didn’t even believe me until he picked up the car., and this car was at a very reputable BMW dealership in Atlanta I just was blown away
Great job finding the issue so fast! Even better job explaining the problem & solution.
Two thumbs up!!
We just had a local mechanic retire and sell his building to a younger, eager guy who freshened up the place and started another garage. The only tech he could hire is a 63 year old guy. Nobody wants to work, we are too comfy as a species. Less and less go into trades as well. It's a bummer.
Doubt that, it's called being paid a livable and decent wage. A young mechanic can't afford minimum wage or the equivalent with the current cost of living, especially rent.
If all he can find is a guy who should be retired I'd bet my bottom dollar the wages offered are crap
"Everybody is a mechanic" but very, very few have went through trade school, have a professional set of tools, and the years of accumulated experience to back that statement up!
Because the capitalist model rewards shrewdness and greed not skill unless you're a doctor. I've said it before, somebody like Grimes and Magic Mike should be earning at least $100k/yr working for somebody else.
I own a automotive business and installing North Carolina thanks thank you car wizard for the channel and ideas that I could use to progress my business. I really appreciate it. I’ve been following your channel for almost 5 years now I misunderstood.
