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.
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.
Does my heart so good man. God bless you brother. Thank you for encouraging me. Your timing is ordained. You have no idea
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.
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.
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.
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.
Thanks so much Alimin Waloyo!
❤❤❤❤❤شكرا استاذه
been a tech 23 years & still learn from you danner. Thanks for rhat... Jason h
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 !
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.
You’re my new favorite dude on RUclips, 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!
As a first year apprentice, I get a lot of information from you. I really appreciate it. Thank you so much
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!
Just like the Bible, I learn something new everytime I watch your videos for the uncountable time. Thank you for your service.
Nicely done Paul, good to see that the premium website is running good and you haven’t let RUclips slow you down.
Great video Paul. Like always.... Keep them coming. You are one of the youtube greats
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
I like all your videos but this time I really like Pete's cozy garage with fireplace in the background!!
Always a good case study no matter what tools are used because the fundamentals are explained clearly.
Love your video, and as a father, it was even more satisfying to watch when you had your son participate.
Brilliant video once again,thanks for taking the time to share all the procedures and explain them so simply and clearly,great to see Caleb having fun with his old man!!God bless 👍 👍
Learning & becoming a better Tech every time I watch your Vids
Thanks Danner
thank you for putting all the time showing this. It is lovely to see you use your knowledge and logical thinking to work through this problem. Wonderfull to see your enthousiasm you must love your job !
Thanks Paul and Caleb, the best team ever is a family :)
Thanks ScannerDanner you're my favorite youtube mechanic, even if you're dealing with a completely different car with a completely different problem I somehow always seem to get some useful information.
Thank you Paul. I appreciate your work. Bless You and your family.
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.
you're a good man. great job with the video Kaleb.
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 !
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 :-)
Another information packed video, love the Pico scope detail as well as the schematic analysis. I have your ebook and refer to it often when trouble shooting my own cars.
Great job master!
Thanks Eric! But I'm no master, just having some fun with my boy :-)
Nice to see somebody dedicated to their work, very nice job.
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.
Would love to see a video with Paul and Eric O!
Boxers or briefs?
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.
Thank you my friend
Great learning session with the basics in troubleshooting !! I appreciate your training and patience Paul, God bless.
Thanks for another great step by step troubleshooting video. Priceless!
Scanner Danner, you have a really firm grasp of the obvious. In all "seriousity" though, learning a lot. Thanks.
I don't even wait to see the vid before I give it the thumbs up. It's automatic now with Danners channel.
Thank you very much. You are a wonderful teacher and your style is great in providing information
No doubt in my mind, Scanner Danner is a complete genius!
to be honest you make us understand more in a very smart way and to be on a higher level
Excellent..as always..Thank you Paul for being out there and helping us..the DIY.God bless you and your family..Greetings from Greece..
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
Thanks for the encouragement Mark!
My pleasure
Excellent job first to your son (great visual audio) and yes you for best automotive instructor. God has blessed you with a special gift .
Thank you Alan!
Love watching your videos because I learn a lot.
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.
Thank you Richard!
Bbn
You will be remembered. Danner. That’s for sure. Thank. You. For. Everything
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 ..
48:36 plastic mallet.... 30 bucks...
50:58 hapiness after repairing things .. priceless :)
Thanks for your videos, Im always learning something new
greetings from Czech rep.
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
I'm a tech myself and this was brilliant. Thanks for sharing
Really enjoy all your videos Paul .learning so much by watching them keep them coming great stuff.
The best tutorial ever. This is the guy!
you're one of the best ,a great teacher,keep it up
Thank you so much for your useful lesson . I am retired Radio Officer. I am Greek and I can understand you quite clear!!!
Wow dude, excellent way of explaining things. Your videos are addictive. Excellent work
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 !
Excellent, thanks for taking the time to produce these videos.
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.
Awesome! Thank you
Just wanted to say thanks, you helped me actually test my fuel pump on my 97 c1500 Silverado 5.7 vortec. Huge help for guys Without the high dollar tools. I do like that relay circuit tester though
Thank you Paul. Well done bro I learnt a lot from your channel
Thank u SD .....iam working in this field, I am a regular viewer of ur videos , I learned many things from u....
God bless you Mr Danner, you are the good kind of a teacher 🙏
Both of you guys are amazing thank you for your videos im a college freshmen in auto tech this helps so much build my knowledge
Great demonstration as always! Thanks for sharing
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.
Thank you for recognizing the value in what I'm teaching! Most people do not my friend
hey man hat off for you, you are a blessing to me such a legendary in the field
Great video Paul. Very informative especially if you have a Honda with no schraeder valve on fuel rail. Excellent
Stayed to the end,, you are the man sir!! hat's off!.. learned a lot, Thanks!!

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.....
This is such a great video! Great job with the shooting Caleb! You're such an awesome teacher, and this is the kind of video that turned me on to you! God bless sir! 😄😄
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.
as i always say , best teacher ever !!!
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 !!
Matt from "Schrodingers Box" is my friend. :-) Tell him I said hello
I know he learned from you !!!....AND LET'S USE THAT VACUUM GAUGE IN ONE VIDEO !!....and would be great if you two can get together for a video...it would be EPIC !!!...God Bless !!
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.
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
Love your videos! Keep up the great work!
Awwww man you are like a God to me.... i wanna become like you one day. i already bought your book and resgistered on your website.... Thanks for the wonderful works Teacher!
very good demonstration and professional, thanks Danner.
Paul, another great video!!!!!!
The best as always. Thanks a lot. God bless man.
Thanks a lot for the help I will continue to learn from the masters!
I really enjoy these videos I have a huge love for chasing down electrical issues and wiring cars your videos really help me learn the more advanced tool usage and newer tech one day I hope to get me a scanner that can control modules and do graphs and just control onboard components thank you for the quality content
Good job ,I love watching your videos, my company paid one million dollars for us to learn this ,and you are giving it for free ,thanks
Thanks so much for watching!
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
Thanks Paul. Really helpful, can use the knowledge on my job.
Great work , fantastic knowledge and most of all the energy within you is priceless .
Thanks man .
I appreciate that!
What a great job , you get the best technics ever 👍👌🏻 Thanks Master Paul danner
you been doing this for awhile Scanner Danner thanks alot!!!
I swear watching your videos are better than game of thrones for me!!!
Absolutely brilliant ! Love your videos :)
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.
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
I love your oscilloscope skills I want to get on that level
Brilliant video. Hi from Ireland
Thanks Tim! Hello from the US
tim kiely Hi Tim. Watched the movie Leap Year and now I would love to visit Ireland. How far is Dingle to Dublin? Scanner has great videos. Been watching for years. Thank u!! we
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
No doubt that you are a Hyundai aficionado! Bravo!
Oh man I had a riot @43:00 when you were explaining the test light jumpered across the fuel pump connector. All I could think about was, "Look at them grubby fingers getting all over that interior trim!!" :D My boss woulda tore a strip off me haha!
Great video as always though. True sign of experience was in the beginning when you heard the funny crank and saw the funny bank 2 cam position pid yet didn't get distracted by it. @4:30 you can see the bank2 cam pos is doing a mirror of the RPM pid. Would be super easy to get sucked down that path instead of just making a mental note and carrying on with initial diagnosis to see where you end up!
Excellent professional job and logic initiative, really inspiring.
formatif and informatif , nice
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.
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
U R a genius Paul!
