No Start Testing Basics - Spark, Injector Pulse and Fuel Pressure (Hyundai Santa Fe)

[@alexsafri2285]

ScannerDanner I want to thank you again for your videos, because I have learned a lot from you about testing circuits. About a month and a half ago I started having intermittent no crank no start issues. At that time I replaced an ignition switch after watching one of your videos, unfortunately that wasn't the issue. But your video started me on the journey that kept pushing me to try and solve the mystery. Your videos are the most detailed even to me who never held a volt meter or a test light in my life. After changing the ignition switch and realizing that it was not the problem I started focusing on your videos. I learned more and more every day. My intermittent no crank no start persisted. Once a week, twice a week, my car left me stranded. Today I finally solved it. It was a single partially broken wire from battery to pcm. One day I realized whenever I had no crank I also had no check engine light. And that started me on the path of working up the courage to actually dig in deeper under the hood. Unfortunately mechanics throw parts at vehicles without even turning on any of the basic tools that you teach us how to use. And they are really not that hard to use. Especially for someone who is supposedly schooled to use them for trouble shooting. When I realized that my check engine light was gone and there was a very good possibility that it was pcm related I didn't even want to go near a mechanic. For a simple reason, because just like how they changed my starter at the beginning when this problem started without even testing the circuits, or fuses, I was afraid they would do the same thing with the pcm. So I kept watching your videos. And I found a single red/white wire that had a tiny little hole on the plastic and as I jiggled it it had white powder like substance (corroded away wire) falling out of it. I split the wire touched it together, check engine light appeared. I also had a random stall problem too. So turns out this very same wire was causing that too. I started the car up and while running I pulled the wire apart. And it stalled instantly. I recreated both issues to make sure that wire was both capable of causing the no crank no check engine light,and the stalling as well. My point is that I really appreciate your videos because you most likely saved me from wasting money on parts I never even needed in the first place. Money that I don't have much to waste to begin with. Having an unreliable vehicle is very stressful. And you help those of us who don't have the means to just replace everything until we find the actual problem. I'm really very grateful and I wanted to share my unfortunate and prolonged story, and thank the person who's online guidance helped me to finally fix it. Thanks for your videos, they are very educational, and helpful.

[@ScannerDanner]

Does my heart so good man. God bless you brother. Thank you for encouraging me. Your timing is ordained. You have no idea

[@kalebpaterson1747]

Way to go for figuring out that a small corroded wire was causing all your issues. That is a serious challenge. I can relate to this post, often times I forget that I can in fact accomplish anything that I put my mind to. Sometimes it takes persistence and courage.

[@jeffhesse8415]

Reminds me of my auto mechanic teacher back in the 80's(race car driver Arnie Knepper), he would not show us or let us take shortcuts until we first learned how to thoroughly diagnose and repair the problem. His reasoning was for us to understand what we do so we're not lost when the shortcuts don't work. A very valuable lesson Paul. Thanks for sharing.

[@aliminwaloyo5004]

Oh man. You’re definitely far beyond just car technician. You could elaborate complicated diagnostic issue into a piece of cake one with your systematic and easy to follow procedures. You’re a legend. Thanks alot. Hello from far far away fan in Indonesia.

[@ScannerDanner]

Thanks so much Alimin Waloyo!

[@user-xm5qs4dj3p]

❤❤❤❤❤شكرا استاذه

[@PANOS9916]

I also do agree with this

[@Altermyego-]

You’ve really influenced my trouble shooting aptitude definitely for the better. I spend less time diagnosing and not easily sidetracked. It’s really nice to not be a “parts changer”. Your service is appreciated.

[@jasonhavers5961]

been a tech 23 years & still learn from you danner. Thanks for rhat... Jason h

[@Turbotomass]

Jason Havers there's too much to know in automotive and it keeps increases each year. problem is the respect and pay for us techs. $40-50 an hour !

[@ronc4146]

At 30:00 to 40:00 , and again from 49:00 to the end, this is far and away the clearest, most concise explanation of the use of the AES Wave uActivate I have seen ANYWHERE on YT or the elsewhere on the internet. Both with and without the use of a scope and amp clamp. AES should stitch these two segments together just to show the tools versatility, and with proper knowledge to back its use up, also add speed to the diagnostic process. I love mine, and am shocked by many who bought it (incl the older version) and whom have never used it, or are maddingly, blindly unaware of its capabilities. Of course, one must have a full and clear understanding of automotive electrical theory to put it to its best use, and also not misuse it, or you could seriously damage components (similar to weaponizing a Power Probe if you don't know what you are doing) by sticking other tools into the banana jacks (doubling as test ports), like for example a Power Probe or test light into the wrong ports. Sure, if you've been around for awhile you probably can already do the same with a multimeter, test light and a fused jumper, like a lot have been doing. But for someone who hasn't, and is trying to speed up the diagnostic process, this works very well. Well done, sir.

[@maryccadena82]

I think it's awesome u showing your son I I have a 2002 Hyundai Santa Fe starter went out change starter put new one changed fuel pump put new one still crank no start but I do think it is awesome that you are showing your son how to do all these steps I've learned lots as well from you

[@emtscythe3782]

Great video Paul. I don't think people realize how invaluable your videos are. I've been in the business a little over 20 years and electrical/electronics diag was always my weak point. I have learned so much from you over the years. I have been to numerous training seminars and classes over the years that cost $1000s and they teach the same things your u are but not NEARLY as in depth or as well. You've u provide a great service brother. God Bless.

[@georgerocks5191]

I did not read the 406 comments for this video, so maybe someone already mentioned this. You say resistance goes down with temperature. It goes up. You saw this with the current. It initially was 2.5 amps(cold bulb-low resistance-high current flow) but decreased to about 1 (hot bulb-high resistance-low current flow). Probably misspoke. Great videos but a little verbose. Could be cut down and still get all your excellent knowledge across. Great teacher. Very informative videos

[@nandor690]

I’m not sure how many fuel pump videos I have watched from you in the last 4 years but I love everyone. It helps to reenforce the theory and test you use.

[@amadoterte1714]

Mr Paul Danner, thank you for showing us the proper method of troubleshooting automotive electrical systems, especially all the basic steps on how to execute the job.

[@ScannerDanner]

Thank you for recognizing the value in what I'm teaching! Most people do not my friend

[@periklisgewrgiou5327]

Thank you so much for your useful lesson . I am retired Radio Officer. I am Greek and I can understand you quite clear!!!

[@JTapia512]

These videos are priceless so much knowledge to troubleshoot. Watching your videos have helped me diagnose vehicles. I actually have my 9yr old daughter watch these videos so she learns that everything has a method and a process and both our problem solving skills have been amplified from my family to yours thank you for all the work and time you put into these videos.

[@ScannerDanner]

Awesome! Thank you

[@craigbaggett3370]

Love your process… if you beat 36:38 on the tank, you might actually cause a bad ground to get good enough to make the pump run and it wouldn’t be a bad pump. It may just be a bad ground and it will show up again later if maybe the tank itself was not grounded or wherever it grounds to .

[@ahmedelzade3326]

There are no words to thank you for this wonderful explanation. You are the godfather of diagnosis

[@ericverster4069]

Your videos are so well put together man! 2nd year a tech here. Just got my first scope, the little aes uscope and Im already obsessed with it. Thanks for posting!

[@mike-yp1uk]

Always a good case study no matter what tools are used because the fundamentals are explained clearly.

[@BigDog50001]

Nicely done Paul, good to see that the premium website is running good and you haven’t let KZbin slow you down.

[@mrkttrdr2919]

Another complete analysis, I can see how u wrote the book on all ur diags, fun to watch u light up as u go through the discovery of the process, ur enthusiasm is rubbing off on grasshopper

[@ScannerDanner]

Thanks for the encouragement Mark!

[@mrkttrdr2919]

My pleasure

[@MrBlazenBruce]

Amazing video and Great timing, a V10 Excursion came into the chain store I work at as a tech yesterday 1-20-18, Possible faulty fuel pump on ticket, Long story short , if the tech that ( started ) to diagnose the problem didn't send it away because of aftermarket wires under the dash- I would have done very similar in my testing, After seeing this video it makes me question his skills for one thing, and why he didn't check for current at the pump wiring and or check the pump for ground, he did raise the vehicle and listen for pump noise when someone turned the key, but did not go any further than checking fuse/relays and ear testing, If the vehicle is still in the shop I will myself test this with a test light and leads and see if current is making it to the pump and checking pump for ground, Thank you for you knowledge and willingness to teach and show others fancy tools are not always needed in some cases, This excursion can be tested the same way and I would love to do it for A theory and B Wanting to be more confident in my diagnosing and repairs, Again thank you for this video and Keep up the great work !

[@edwardpatalon1701]

Love your video, and as a father, it was even more satisfying to watch when you had your son participate.

[@herminioguzman4887]

It is difficult to find a combination of knowledge, ease of teaching, and amenity. and that's what I found in this video. Congratulations. It is shown that solving automotive problems can be both efficient and fun at the same time. Great work Thanks for sharing

[@peteleoni9665]

Scanner Danner, you have a really firm grasp of the obvious. In all "seriousity" though, learning a lot. Thanks.

[@chungaleta1234]

Hope I can come out clear with my poor English... It is not how much you know (Which is shitloads of knowledge) but how good you are at teaching. If we could have instructors as good as you in every field of education... The world would be so much different!!!!! Hats off to you Paul. Thanks

[@larrylamb3480]

I really appreciate your common sense approach to diagnosis testing and your patient explaining of your diagnosis ! Your an excellent teacher, keep up the good work and I subscribed to your channel ! Thanks again !

[@ScannerDanner]

Thank you Larry! Good to have you with me. I see all comments, no matter how old the videos are. Looking forward to hearing from you more :-)

[@jessetravella8284]

You’re my new favorite dude on KZbin, outstanding job! I’ve always used a light and meter but a picoscope and computer are looking like a nice upgrade! Thanks for the video keep it coming!

[@corb532]

My Hyundai wouldn't start; my mechanic could not solve problem. I watched your video and suggested a new battery which solved the problem! Thanks Danner. I live north of New York City, or would have used your garage.

[@alangaudry724]

Excellent job first to your son (great visual audio) and yes you for best automotive instructor. God has blessed you with a special gift .

[@ScannerDanner]

Thank you Alan!

[@McGuigan21]

So essentially, if my learnings today are correct, I could essentially hook my test light to battery positive and then probe pin 87. If light is present it confirms I have ground, decent brushes, and intact wiring or of course if no light, I have an issue with at least 1 of the 3. This all seems too good to be true lol, this can be done within minutes as well as the convenience of staying under the hood. Thank you for all the knowledge you share with us, you make me feel like I could actually do this for a living if I ever wanted to give up machining.

[@ScannerDanner]

yes sir, but keep in mind that it only tell you there is continuity, it does NOT mean the circuit and pump is good. You may have to circle back on that leg of the circuit if everything else tests good, but yes, it is a great first step on any load side of a relay circuit

[@jeremiahschaefer6670]

Just like the Bible, I learn something new everytime I watch your videos for the uncountable time. Thank you for your service.

[@SouthMainAuto]

Great job master!

[@ScannerDanner]

Thanks Eric! But I'm no master, just having some fun with my boy :-)

[@jordankahele14]

Nice to see somebody dedicated to their work, very nice job.

[@orestino6212]

Eric, you are too nice. You make everything simpler in your videos. You are a MASTER Mechanic. He was using expensive equipment, when he can be using a spark checker, volt meter and a light.

[@tvguy12346]

Would love to see a video with Paul and Eric O!

[@stebertwoody34]

Boxers or briefs?

[@zoticus1]

excellent diagnostics format as usual. I've been seeing what appears as fuel pump failures in modern modular pump circuits with the actual failure at the plug from the pump to the harness plug internally. good pump, bad connection internally. something to consider

[@japhetmacaya5326]

Im from philippines.everyday i watch all of your videos.and its great.im a helper auto mechanic here and i want to become lke you someday.....

[@TheGibby3340]

Nice. Excellent point about why waste time "plumbing" in a fuel pressure gauge if their is no current draw on the pump circuit! Thanx again.

[@ripcordres]

Great Video, Elimination of variables and the root cause shows itself. Why would they not have the Schrader valves anymore? It must be a cost matter and building the cheapest way without service in the loop.

[@jamesdean5087]

I like all your videos but this time I really like Pete's cozy garage with fireplace in the background!!

[@arcadiogalindez6407]

I continue to say it man do I learn a butt load of stuff In every video it just puts a smile on my face ..it raises my confidence ..so I will say thank you for that ..really I mean it ..

[@rrmech11]

Paul This type video is what made you my brother many years ago. And now you have a wonderful son as your camera guy. Really enjoyed watching you make poor pete constantly turning the key in all your videos at his shop. It's a riot.

Hey Paul !!...I've been watching your videos these last few months and have learned SO much...Thanks and God Bless !!!..your diagnostic troubleshooting is simply amazing...I'm still kind of "old school" and was hoping you'd do a video on using a vacuum gauge for some of us DIY'ers !!...I always keep my vehicles in tip top shape (a 2001 Corvette with 55,000 miles and my new 2016 4 Runner) so I never get a chance to fix anything !!...I gave my old 2005 Ford Escape to my girlfriends daughter and it had 345,000 plus miles and was still going strong....basically all the BIG parts that failed were the fuel pump, alternator (a bitch to change), crappy CD4E transmission at 280,000 miles...I guess the truck was built on a Wednesday...LOL !!...looking forward to some new videos...I also watch Matt from "Schrodingers Box"...have you seen any of his videos??...a very SMART non-pro technician with skills !!!RobUnion Beach,NJP.S. Worked as a Jet Engine and Airline Mechanic/ Inspector in the Airline industry and Military for over 40 years but working on cars is and will ALWAYS be my first love !!

I am new to this but when checking the pulse on the coil I notice on the left it shows 350v I am to assume this is volts. if in fact it is can this be measured with a volt meter.

[@Thefox2000unit]

I don't even wait to see the vid before I give it the thumbs up. It's automatic now with Danners channel.

[@ramzizakaria499]

God bless you Mr Danner, you are the good kind of a teacher 🙏

[@UNEEK_LOGIK]

Learning & becoming a better Tech every time I watch your Vids Thanks Danner

[@1Wayfix]

You will be remembered. Danner. That’s for sure. Thank. You. For. Everything

[@jonka1]

One absolute test for the pump is to apply 12v to it. This removes any doubts about poor or intermittent connections. I've seen lots of cars with new pumps and relays with an intermittent wiring fault.

[@ScannerDanner]

There were no doubts. Learn to trust your meter and you won't need to jump components directly. I never do.

[@dukeman7595]

Dan you are almost as good as Eric at South Main Auto, and that is high praise to be on his level, it's like walking in tall timber!

Eric is the man for sure. Thank you!

[@ScannerDanner]

Oh and my name is Paul Danner btw

[@adeljad4735]

thank you i like your reality how you explain i know you can just fix the car in minutes but you are really great you let people know what problem you could face in real diagnostic.

[@rhondaremus21]

I hope your son realizes how much information you're actually giving him enjoy your videos they are they are intense not always on the exact subject but definitely definitely knowledgeable you are thorough and an explanatory facts factsI have a stupid 94 Lincoln town car with this exact problem I actually took out the injectors and clean them myself put them back in now I don't have any spark thought it was a fuel pump but it could be a relay so........

[@bibinemmanuel7375]

Thank u SD .....iam working in this field, I am a regular viewer of ur videos , I learned many things from u....

[@wyattoneable]

Excellent review of chapter 3 material. Excellent editing, and thanks for showing us how you connect the test leads. That's a cool tool you used to verify the relay. I like it when you get excited, it confirms you really love what you do.

One of the best tools I've ever used. For real, love this tool

[@19kirindog76]

i learned a lot on this video... for this kind of technical problem i love the way you dont shorcut anything.. do you have and videos that had power feed from Fuse boxes and lines but not getting power and pulse from injectors.. or getting power from battery to fuse boxes to ECM but ECM dont give voltage to injectors

[@ScannerDanner]

Check out my chapters 17 and 18 playlist (fuel injector testing) Thank you!

[@albertdelosreyes7026]

Excellent diagnosing.,Works mostly on Hyundai and kia but most of the time CRDI. Cheers from the Philillines.;)

[@ScannerDanner]

Thank you Albert! Cheers from the US

[@davidhall3747]

Another way to check the fuel pump continuity. Remove fuel pump relay- probe pin (87)- and green led on power probe should illuminate. If not- you have a open circuit. Power Probe- makes your life easier.

[@jasonmcfarlane7047]

Really enjoy all your videos Paul .learning so much by watching them keep them coming great stuff.

[@dangore590]

just saying .whats up bud (back at ya ) all your videos are great so keep them coming ,,been working on cars for a while and i learn new tricks and tips ever day know that i watch your videos, so keep the case study"s coming

[@30kendel]

Awesome diagnose paul!!! Electrical test before pressure test...in this case fuel electrical circuit.

[@DavidS11]

I've worked on hundreds of these cars, but I only had to change a couple of fuel pumps, so it's not a very common problem but it does happen. Sometimes it's a bad connection inside the pump that draws tons of current and it ends up getting burnt. Luckily most Hyundais have an access cover under the seats. Another method I've done to check lack of fuel on hyundais is to open the line just before the rail, and put a recipient to catch the gas. In cases where the pump doesn't even turn on works great, but not recommended for other cases where you might have some pressure(although symptoms would be slightly different).

[@claudiofigueiredo6357]

Wow dude, excellent way of explaining things. Your videos are addictive. Excellent work

[@hayguey7952]

U are the man.love ur videos I'm learning sooo much from ur videos.an the tools i need.i will b getting the relay tool thanks

[@Gagik5779]

Greate video Paul I like your tool fuse current loop ,168mA current I think that it is relay coil current when you are checking at the first time on scope

[@frugalprepper]

I can tell you about the time I learned to always check for current draw. I made sure I had voltage to pump, put a 2 amp light across pump feed and ground and had light. Couldn't hear any pump running. Called a pump. Ordered Pump, when to put it in and pulled old pump. Not a drop of gas in the thing. Fuel gauge was wrong. Turned out to be a bad instrument cluster that I had to send out to united radio, pump was fine. Luckily I could return new pump since it was unopened.

[@christheother9088]

As I recall Hyundai sells a little kit to install a fuel pressure test valve. Also the Santa Fe's had some corrosion problems and leaking with their fuel tanks. Had to replace mine. Go easy banging on them!

[@ScannerDanner]

good tip, thanks!

[@jandbworks2023]

Excellent professional job and logic initiative, really inspiring.

[@philtebo5155]

Absolutely love the uActivate

[@Pablo_Automotive]

Thanks Paul and Caleb, the best team ever is a family :)

[@mikeoneill7360]

Awesome, like you earlier, what would you do if the pressure was zero, you injected starter fluid, and banged on the tank and nothing happened. You’ve demonstrated these techniques, not that easy to understand, but I will watch this video multiple times until I feel more comfortable. Thanks again Paul....
