What a moving story about Rafael Venezuela - I do hope I have spelt it correctly. And how lovely of his daughter to write to you and tell you the difference you made to her father’s life. That’s something you’ll always be able to fall back on, on those occasions when you spill your coffee all over the car, and the new ECU doesn’t fix it, and you wonder why you ever became an auto diagnostician. It’s a wonderful, moving story, and kind of you to let us all in on it. I think every one of us can relate to it. Thank you so much, Paul.
😀 my man. You must be a premium member 😊 to be mentioning spilled coffee and a bad call. Thank you so much! Thanks for the encouragement here on YT too
@@ScannerDanner Yes, indeed, Paul; I’m a long-standing Premium member, and proud to be so! The stuff I’ve learned - theory and practice, and the confidence I have gained to apply that knowledge - is worth at least a thousand times the cost of Premium membership. And I’m just a hobbyist!

Lump in my throat here. I can relate, I lost my brother in 21 and while I was hiding from the world I looked forward to these videos and still do. You know how I feel no need to harp on but that's an amazing story.
you help people a lot direct and indirectly I can help someone and are helping who could not afford to have a car if I had not gotten help from you to learn diagnostic skills to repair cars, so you help poor people to have freedom and easier life to afford an old car thanks Caleb and Danners brothers for your work
When i started on my own vehicles back in 2013 i hadn't got a clue about OBD2,what's ODD2,oxygen sensor?,Map sensor?,Maf sensor?,trouble codes ?,but, i was willing to learn and i learn't so much from you,i used to watch you in the classroom teaching your students and was fascinated by it all i even became a premium member for a while,oh yeah forgot about fuel trims couldn't get me head around that one for some time but eventually the penny dropped. The message you read out is so true,you draw people towards you becuase you are a genuine guy 🙏.
The most valuable gift I've been given came from Paul... I was gifted a voucher, with it I got myself some tool ... Thanks to SD, he's a great teacher and philanthropist
I can so relate to what she said , I wish I'd had you as my teacher when I was 16 and struggling through my apprenticeship and like you given stupid books and struggling to understand why I need to know about how hall effects are made but nothing about how to test them on the car etc. You give me something to look forward to when I watch your videos and I love the fact you are such a genuine honest caring person and take time out of your busy life to produce these for us. I thank you sir from the bottom of my heart.
Paul you Erik O Ivan PHD Cuba don't know how much you contribute to us. I a blessed to have a good job in computer I.T. All your guidance allows me to help Veterans and people on fixed incomes. To fix their cars when they can't afford to take it to a mechanic. They pay for the parts only. My time is free. They know I am not as fast the aforementioned group. but also know I will try my best and not be a part changer. Thanks for all you do.
Your faith and honest approach to diagnosing intermittent problems as well as owner unable to give you any history is refreshing. Recording the mistakes rather than editing them out is another display of your integrity on that PT Loser door switch. We have all been there multiple times.
Bro u have no idea how much u help with teaching what u know. I can’t afford a lot right now so I always resort to u tube in help me learn how to diagnose. Thank u and keep chalices man God Bless
In addition to all the great "how to fix it" info you give us via your videos, you are one of the genuinely good guys here on UA-cam! I am honored to know you and count you as a friend, even if it is just virtually! 🙂
Thanks for your generosity and sharing your faith! I'm with you all the way! Just wanted to share what I wrote to you so everyone can read it. "Hey Paul, just wanted you to know that I was able to teach my brother who's a parts changer how to test and make sure the sensor has power and ground before replacing the CPM.

I had the same issue on a 2008 Buick Enclave, I scoped both injector and coil powers. When the injectors dropped out, so did the coils, but only set the injector codes. I found that the screws that held the connectors to the bottom of the fuse box were stripped. I ended up putting cardboard underneath of the connectors then snapped in the fuse box and it cured the issue. That was several months ago. By the way, this is my wife's car.
Double thumbs up on this episode Danner, Great human relations content as well as technical content. Makes me feel better in a spiritual way that you’re a man of God… Keep on rockin……
I always refer to OE wiring diagrams for connector location. I find the redrawn color diagrams tend not to show inline connectors. Good video as always Paul!
Technicians/Teachers like you made me stay in this field, after graduating high school everyone told me do not get into automotive field because of how mechanics are and its cut throat field no one is going to teach you. But people like you proved them wrong. Thanks Paul. By the way that link you referred to (3:43) I do not see it. :)
I find Its so hard to charge customers for diagnostic's when your not sure of what the problem is, but your sure what the problem isn't. 35 years it the trade has hardened me be tough and you need to believe in yourself, you have made the right decision, and stick to it.
Your a inspiration to many. Not just by teach us great working diagnostic ways. But also life skills and your a good person I follow you on Facebook and your personal account. I'm glad i get to share your journey in life. My son Roman is autistic and we sit together at bed time and love watching your videos. For some reason yoj keep him calm. Maybe you can give my boy Roman a shout on one of your videos that be amazing. Thanks for all your love my brorher.
It is awesome that you did that for that woman you could have been a typical businessman and said sorry about your luck but you have to pay to many of us in or around this field get a bad wrap because of a few bad apples
Props to you Paul, for being a caring believer before being a mechanic. You just showed us your true hearts priority. John 13:35 By this shall all men know that ye are my disciples, if ye have love one to another.
Awesome intro! Thanks for all you do, tenacity, accuracy, honesty and kindness. I aspire to be as thorough as you, after thirty years in the automotive repair business, every day brings on a new set of challenges, understanding, learning, and of course, humility.
Brother paul.you dont even know how you inspired people by you honest legit work.i am on other side of world learning from you sma and phad oz alad and other guys work as they always mention you in their videos.its a blessing for you to be a inspiration for so many.cheers stay blessed
I hate working for free too, but there have been times that I didn’t; but those rare occasions. Last time I let someone go the came came in for an intermittent check engine light, P0300. Ran the basics in 20 minutes. Unsold brakes Explained to the customer the situation that the care has great history, everything is new, and gave them a form to fill out next time the check engine light appears. I further explained that if I continue diag I will charge for my time and the chances of finding something is slim. Customer returned two days later and I identified the problem. Looking at the worksheet I gave her turned out the boyfriend was using a OBD2 data logger for his job. Always think outside the box I did lose diag time but I won a customer for life. She has since brought all her cars to my shop and only trusts my judgment.
Huge fan been watching for years. I have worked on those vans before and I have seen the injector harness rub threw and ground on the block in the rear of the engine (unfortunately under the dog house)
Having this same issue on my express.. random misfire but only when going above 40 mph. I don't really feel any misfire, CEL just flashes if I start to decelerate. Can't wait until your next vid!
I don't know about a 2015, but older ones of those vans had a problem with the engine harness rubbing through on the left front upper control arm mounting bracket.
Having the same issue with a 2016 4500 Express School Bus, replaced the fuse box and problem was fixed, thanks for the info. I must add our local Chevrolet dealer had it in stock .
I work at a GM dealership and had one of these with the same exact codes on bank one and it was a constant dead misfire on 1,3,5,7 connected a head light bulb to the power feed and it would light it nice and bright. Fuse box fixed it though
As soon you took that fuse out the fuse box and put it back in all those codes are coming back that had my mind thinking as a fuse box or wiring problem we have alot of these work vans where I work at and that's why we see a fuse box laying around inside their good work vans
I wanted to advise you to look along the wires to the injectors as, if one of them shorts to ground, all will lose power and the code will appear. The fuse will also blow or the pins will become loose if the short is very short (in time) and the fuse doesn't have time to blow but the pins get melted a bit. Now that I've seen the end of the video I understand there must be something else. Nice video anyway. I waited for one like this for a long time already. Cheers!
I remember that name in the comments section for sure! I think he may have even been a premium member from your initial service through UA-cam in the early days.
Those intermittents definitely do SUCK!!!! Had an 07-ish I think f150 customer had to bring back 4or 5 time for no crank. Dash, abs, and pcm we're all on the same COM lines. Finally acted up long enough, found the pcm dropping out of the com circuit. The the Cust didn't want to believe us and wanted a second opinion from somewhere else. Have fun son !
Well at least you got a chance to see what’s causing the problem. I think it’s too much of a coincidence that scope reacted to the gear shifter. I think your getting close Paul
Hey paul I have worked on dozens of those gm vans and had that exact problem around a dozen times and every time I monitored the power feed to the injectors and as it gets hot I would lose voltage . The cause was a bad solder joint in fuse box . I dismantled one box and I could see a lose pin on board where the solder was not holding and failed When hot . Hope it helps
you got my eyes leaking at the start you done very nice thing for long time subscriber s daughter big thumbs up mr paul danner well done calebs question reminds me of someone have said right if you change a part and the fault is not fixed what part would look at next check that part before replacing any parts
On intermittent stuff like this, once you have ruled out the obvious check points, I usually then go right to checking the harness; not tearing it apart, but just back track the harness as best you can/ use some mirrors and lights, and just look for something obvious. Because many times it can be right there in your face- a wire bending around a sharp corner and worn through, ect. ect.. We've seen it all 1000 times. Don't spend a lot of time on it-- just give it a once over and look for something to jump out at you--- and then move on. Sometimes we can get a habit of sticking with the scanner and diagrams and overlook a simple visual check. I've found that this can save you time more than you might expect.
I noticed both times you had voltage spikes you was turning the wheel left, maybe a wiring harness near the steering shaft or in the ignition wiring to the key and tumbler? Just a thought buddy
Great video as normal you also need a ground. Although supply cables joints good how's the return neutral. Your pickup is common and your not using the earth the injectors are using. I've had a loose bolt chassis bolt worked ok till drove rough roads vibrates loose. Was hard to find hope find in part 2.
When you don't have much direction to work with on such an intermittent problem, you'd might as well pull and plug all the fuses and relays a few times to eliminate that as the problem. Check any easily accessible pertinent connectors and grounds too. Don't cloud your mind with too much doubt about everything. If the problem persists, you can then start a proper diagnosis with a clearer head. It's not always useful to spend stupid time and money to prove that the problem was just a poor connection at the pin of a relay.
Your comment about charging is a tough one. I have given away a fair amount of time and money due to the fact that I couldn’t find the root cause of an issue.
Thank so much for your uplifting words Christ is the only option I know it not easy been a Christian and working in the motor industry as many of us have used swear words on a daily basis ,but my Christian faith is still with me despite both my parents passing as I said early there is nothing in this world that can compare with our Lord Jesus Christ someone you can trust in theses chaotic times .thank you for your knowledge and dedication to this craft and the great contents
So I had a case earlyer this with the same kinda van. I ran the same test then removed the fuze box and opened it and it was burned inside the fuze box same fault code but mine was not intermittent so sold a fuze box then found the tsbs on this problem
I agree with the logic that it's not likely to have the same problem across all 4 separate wires, so it must be upstream from there-- which would be the fuse box/ fuse.
Don't know if you have found the issue but I had one that come in with the Samy problem. Found the sodder on the fuse pin to be corroded. Orderd new fuse box.
Been there with this one, power distribution schematic will show the trans range sensor in the curcuit as well then you will question Mitchell's competency
Had a similar problem on that same type of van. But instead of injector codes I had misfires and a coil circuit code. Ended up being the ground on the backside of the engine. Had to take the doghouse off and wiggle the harness to get the fault to happen
Each injector is individually grounded by the ECM and then would use a main ECM ground after that. So with a faulty main ECM ground, we would be having more than just one bank of injector issues. Make sense? Great question
G1 is at the same tie point for fuse 65 that could possibly be part of the problem. If it was touching, it could draw down G2 and G3 circuits because all are tied to fuse 65.
Bad alternator? Last time I heard a GM alternator screaming like that, it would charged great when cold but would soon heat to like 500 degrees and intermittently stop charging!! Looks like the scope was picking up some ripple as well. I never look the other way on a screaming alternator since your video on a Buick? that had so much ripple to cause speedometer to jump in park!! Now I'm wondering if the entire vehicle voltage is dropping so low causing the misfire. Thanks for the video, can't wait for part 2....
The idea of FREE is that alot of people think you just plug into the vehicle and the computer tells you the problem. . I explain that testing is required beyond a code point towards a potential system problem. And TESTING IS NOT FREE. . So testing starts at x$ and additional testing is extra. And if the problem is not present when testing then the tests will possibly test ok. . . So there is only TESTING FEES to get to the problem. So the word "diagnostic fee" is never used. . So the customers options is pay for testing or guess. . And RETESTING cost just the same. . . Loose the "Diagnostic fee" , TESTING starts at whatever amount of $ .

When you don't have much direction to work with on such an intermittent problem, you'd might as well pull and plug all the fuses and relays a few times to eliminate that as the problem. Check any easily accessible pertinent connectors and grounds too. Don't cloud your mind with too much doubt about everything. If the problem persists, you can then start a proper diagnosis with a clearer head. It's not always useful to spend stupid time and money to prove that the problem was just a poor connection at the pin of a relay.
Your comment about charging is a tough one. I have given away a fair amount of time and money due to the fact that I couldn’t find the root cause of an issue.
I’m an atheist but I believe there are good people in all walks of life and all faith’s. Thumbs up. 👍🏽
Great job man 👨
I fix one a few years ago was the fuse box
good info. thank you for this video.
Thank so much for your uplifting words Christ is the only option I know it not easy been a Christian and working in the motor industry as many of us have used swear words on a daily basis ,but my Christian faith is still with me despite both my parents passing as I said early there is nothing in this world that can compare with our Lord Jesus Christ someone you can trust in theses chaotic times .thank you for your knowledge and dedication to this craft and the great contents
Thank you my brother in Christ
So I had a case earlyer this with the same kinda van. I ran the same test then removed the fuze box and opened it and it was burned inside the fuze box same fault code but mine was not intermittent so sold a fuze box then found the tsbs on this problem
I had this issue come up on a 5.3 suburban 2008 . Had a bad ground wire on the back of the head
I agree with the logic that it's not likely to have the same problem across all 4 separate wires, so it must be upstream from there-- which would be the fuse box/ fuse.
I love you talking about God.
Don't know if you have found the issue but I had one that come in with the Samy problem. Found the sodder on the fuse pin to be corroded. Orderd new fuse box.
yes sir, check out part 2!
that was nice .
Been there with this one, power distribution schematic will show the trans range sensor in the curcuit as well then you will question Mitchell's competency
Leaving us with a cliffhanger 😬
Had a similar problem on that same type of van. But instead of injector codes I had misfires and a coil circuit code. Ended up being the ground on the backside of the engine. Had to take the doghouse off and wiggle the harness to get the fault to happen
Do all 8 injectors share the same ground, or is that irrelevant?
Each injector is individually grounded by the ECM and then would use a main ECM ground after that. So with a faulty main ECM ground, we would be having more than just one bank of injector issues. Make sense? Great question
190 grand miles could be the life of the fuse box ???
G1 is at the same tie point for fuse 65 that could possibly be part of the problem. If it was touching, it could draw down G2 and G3 circuits because all are tied to fuse 65.
Well spoken,,, reality.
Bad alternator? Last time I heard a GM alternator screaming like that, it would charged great when cold but would soon heat to like 500 degrees and intermittently stop charging!! Looks like the scope was picking up some ripple as well. I never look the other way on a screaming alternator since your video on a Buick? that had so much ripple to cause speedometer to jump in park!! Now I'm wondering if the entire vehicle voltage is dropping so low causing the misfire. Thanks for the video, can't wait for part 2....
Looks like at the end you need to apply parking brake while in gear in the low voltage condition.
The idea of FREE is that alot of people think you just plug into the vehicle and the computer tells you the problem. . I explain that testing is required beyond a code point towards a potential system problem. And TESTING IS NOT FREE. . So testing starts at x$ and additional testing is extra. And if the problem is not present when testing then the tests will possibly test ok. . . So there is only TESTING FEES to get to the problem. So the word "diagnostic fee" is never used. . So the customers options is pay for testing or guess. . And RETESTING cost just the same. . . Loose the "Diagnostic fee" , TESTING starts at whatever amount of $ .
wow a fun one you should have been checking battery vltage at the same time. especially with the alternator singin like that.
