DIY- How to Diagnose a No Start LIKE A BOSS!!!!

[@those1kidds]

"it was just a minor wiring issue, no charge, come and get your car" -- said almost no mechanic every. You're amazing man. I wish you lived near me..... you seem like an honest, awesome guy who just likes to help people. We need more dudes like you in the world (:

[@SchrodingersBox]

Wow thanks man! It helps that I just do this as a hoibby for charity. If I did this for a living I'd probably tell him he needs a new fuel tank and a tuneup for $1200 lol.

[@frank09busa]

as an master tech in the past, I approve this mans method. great explanations, demonstrations and final repair. bravo good sir.

[@acwither]

Man, I don't even have car troubles and I stumbled on your channel. I hate when people get burned by mechanics (or any other service), so I always fix things for myself, family, and friends. Thanks for the awesome vid. It's inspiring to see someone helping out and fixing 'a professional's' mistakes. I can't imagine what trouble this guy would have gone through had he taken the car back to that same mechanic.

[@robertmckinney4772]

FREE OF CHARGE!!??!! PICK YOU UP IF YOU NEED A RIDE TO COME GET YOUR CAR??!!?? You are doing gods work my friend.

[@jamessmejkal8803]

I really like this home mechanic, NO BS, just straight talk.

[@tazmaniandiva7762]

Not a bad guy at all! It is so hard to find mechanics that perform diagnosis like this. Sadly most just throw parts at it at the customer's expense. Wish I could find a knowledgeable AND honest mechanic like him.

[@feddiegangbigfeddie361]

You just got yourself another subscriber brother. I'm in my journey of starting a repair and customization shop. I really like how you looked out for the customer with LABOR at NO CHARGE! AWESOME! Your channel is, from what I just saw, the perfect way to learn how to not only work on cars, but how to run my shop and how to treat my customers. Thanks for the great show✌🏾

[@SchrodingersBox]

Awesome thank you!!

[@mrghiax]

Top draw super fast diagnosis Matt. Professional parts changers should be embarrassed and ashamed of themselves watching you in action Matt. As a chap commented below - his local mechanic would have changed everything, probably charged the customer a small fortune and still the car wouldn't start!! You are definitely more a professional than most "professionals" can ever hope to be!

[@jrmasson222]

Impressive which leaves me with one question. ....why is the guy not bending over so far backwards with gratuity that he risks getting his head caught up his %$$....oh I answered my own question. I bought a greeting card that read , sorry i missed your birthday my problem is obvious, with a picture of a guy in that position.

[@mikesaltman]

And that’s why I decided not to let anyone work on my cars ever again. Got tired of getting taken advantage of. Now I do all my own work, not that I know how but I have a book for each car and KZbin. Sometimes my cars sit for months while I try to figure out the problem. But I would rather my car sit there and I bum rides for however long it takes than pay out $800 to a mechanic and it not fix the problem or fixed things that didn’t need fixing

[@gereral1_jackofalltrades]

Great video. Glad there are honest people out there. Problem with the upright approach is most mechanics would rather charge you for a fuel pump so they make some money off you. You can see it in your channel that people see the true you and support you by subscribing to your channel and watching your videos. I like your approach on fixing cars.

[@SchrodingersBox]

+gereral1 Thanks bro... hey how's the grandkid? Like 2 years now?

[@gereral1_jackofalltrades]

Merritt 1 year and a bit.... thanks for asking

[@Stambo59]

+gereral1 As a professional it embarrasses me when I hear stories about people being conned by others in my trade. Not all of us are dishonest. Some of my customers I have had for 30 plus years because they trust me 100%. I was taught at a very young age to treat people as you wish to be treated and this has helped me build a successful business. Going back to the video, there was a couple of things I may have done slightly differently but that comes down to 40 plus years of experience. Still a nice find, and one many professionals would have had a problem with. I await the results of your other "non runner" with interest. :-)

[@SchrodingersBox]

Stambo What would you have done differently?

[@Stambo59]

+Schrodingers Box I do stress differently, not necessarily better. Once a lack of fuel was confirmed, I use a barbecue bottle with a regulator and a longish hose instead of starter fluid. It is way cheaper and dissipates very quickly if you still have a non starter. It is also possible with a bit of trial and error to sit the bottle inside and drive the vehicle this way. I also probably would have started at the relay end of the fuel system and confirmed KOEO prime and directly bypassed the relay before crawling under the vehicle, but then I am in my mid 50s so crawling under a vehicle tends to come later in my process. The end result would have still been the same :-). Please don't take this as criticizing your method as it is not intended this way. Your methodical approach is very similar to my own. I don't like replacing things until I can prove without a doubt that they are faulty.

[@moedawg4061]

Most mechanics are not truthful when it’s a simple job fix .. good deal showing the call .. much respect

[@vieiraandre6332]

Mechanics like you are hard to find Matt, how I wished you lived in Cape Town South Africa... Stay real, you're the real boss.

[@kennethgeelhaar872]

Glad that you found this problem. FYI - Isuzu's alternator have a separate circuit to power the fuel pump relay when the alternator is spinning. This is to turn off the fuel pump after a collision. If the alternator is wonky, then the motor will try to start, but will not stay running. It stalls out as soon as you release the starter. Sometimes it is the alternator failing. Sometimes it is the fuel pump failing. My work buddy is crazy about Isuzu and passed on this valuable tip to me and I hope that with posting this comment it helps you or someone else in the future.

[@adriannyasia]

[@alexm2623]

'Bout freakin' time I found a fellow scientist into car repair and general DIY stuff. This channel is just what I wanted - I hate sorting through 45 minute videos looking for those 30 second tidbits of info I need buried in 44 minutes of people grunting and ratcheting while generally providing no useful information.

[@SchrodingersBox]

Hahaha, not too many people share our perspective. I agree though- it is distrubing how many people out there will spend all day watching guys grunting.

[@alexm2623]

I usually play the video at 2x speed to find what I'm looking for (usually a "How the hell do you get to that bolt to take it off without breaking something?" or tips and tricks for some inspiration and clever thinking that hadn't occurred to me). I'm just a guy looking for a quick answer without fluff because I just want to get the job done. I don't give a shit about mechanic vs tech, tool trucks, or whatever other BS people argue about. I just don't get the automotive culture. I roll my eyes so hard I worry about them leaving all together when I see tool snobs pushing their $400 Snap-On crap that they're still making payments on and bashing Harbor Freight and Craftsman. It just doesn't compute with me. If both tools get the job done, how on earth can you justify a tool that cost $380 more if the end result is the same? Then you have people on the opposite side who pay through the nose because they can't do a simple brake job or oil change. When I started this reply I didn't mean for it to be a rant, but there you have it, lol I think it all pent up as I searched through 10 videos to find out if I had to drop the gas tank to do a fuel pump or if I could go through an access panel in the trunk getting more frustrated with each video because I could've dropped the tank and just looked myself faster. (Didn't want to check in the trunk because it was packed to capacity of all kinds of junk I didn't want to mess with.) I'll be a regular viewer of your channel for both the repairs and humor, as well as scientific diagnoses.

[@grantlandking4361]

Alex, thank you dude! Your post was therapy. Anybody who read as far as the word "rant" knows it's anything but. You laid it out direct. You're one of the very few people who still practice the rare art of "thinking" in order to learn new info so they gain efficiency in making wiser choices when problem solving. And why are we this way? In the pursuit of happiness, for us and our loved ones! Any excess talking, chrome, or tales of yore impede this goal. And we cant imagine forcing someone to endure a shitty story or advert. in order to share useful info with em. We like to get sh!t done so we can hose-off, put meat on the grill, and chill with the fam & friends. I have come to appreciate videos and people like Mr. Schrodinger who is happy to help his fellow man. It works out for the good in life and many people are so distracted or arrogant they'll never get it. That's why God set a premium on these words "Thou shalt love thy neighbor as thyself". It becomes apparent rather quickly these days who people have love for. ~hint: if somebody talks just way too much in general, and/or throws out two or more stupid non-witty jokes....their neighbor is in every mirror they look at. Take it easy brother!

[@myjrny2]

Dang, it's just too bad there are many mechanics out there that will take advantage of the situation and lie and create another "problem" to the diagnosis then charge you an arm and a leg for it. It all comes down to morals, dignity and honesty! If you don't have any morals or conscience, one would lie and take advantage of the customer and basically steal that way. It's so hard to find a good and honest mechanic! Wished all mechanics was like this guy!

Same here and I don’t have any dx tools. I changed fuse, relay and filter. Almost starts and then blah😤 I’m horrible with electronics

[@gvvq-pi5ml]

I think you actually done really well there Matt, just one comment, with your normal circuit tester and the pump plugged in you could by pass the relay check for current there and put the tester on the ground wire, if you have a bad ground the tester would light on the ground side....bit like a headlight that doesn't work...Fred.

[@frankligas2249]

Thanks for the video. The one thing I would have recommended would be to always check the main ground connection by the battery. Manufacturers almost always paint the car, then drill a whole through the paint, and thread the whole. The master ground connector for the whole vehicle is grounded to the frame with a bolt going through an eyelet, so the only connection is the threads of the bolt in the whole. This will always corrode over time and cause intermittent issues with various electrical systems. Even if it is not the problem, it is always a quick recommendation to pull the master ground connection off, sand the paint off of the frame, then sand the eyelet to the ground connector, then coat the connection with battery terminal grease and reconnect. That way you fix or prevent most all issues related to poor grounding conditions.

[@SchrodingersBox]

in general good advice however we know from the very beginning this cannot possibly be a ground problem so I didn’t go that direction since there was no need to.

[@mannyvelez4437]

hey Matt this is another great video like the ones before. sometimes I get customers at my shop where they have spent hundreds of dollars and they get tow to my shop and it turns out to be simple fix. at that point my intention would be no charge,but I have and overhead and a family to support. so at least I charge a small fee. again I've learn a lot from your other videos.

[@SchrodingersBox]

+Manny Velez Oh totally as a professional you SHOULD charge for doing a diagnostic (as long as it's accurate) and also for any repair. It's a business! for me it's a hobby though.

[@olipirard]

Hi, This is a really good approach of the problem. The good think is that you showed us diagnostic with simple tools. The paperclip trick to bypass a relay is just awesome. Thank you.

[@fificboi]

you definitely know what the hell you're doing! man wish I knew someone like you here to help because you're right most mechanics will just go on and change parts they assume is the problem but it wasn't and they keep doing it until they find the problem which puts you out of money from buying all the unnecessary parts in the first place

[@martystevens3969]

Scanners can help lead a mechanic to the area of a problem. It can show other problems. It all depends on the problem. Sometimes basic troubleshooting is faster than a scanner. Scanners can tell you a part is bad when it's good like an O2 sensor is rich when really it's the mixture. One part makes it appear that a part is bad. A ISC motor can throw Ox. sensor codes. Mechanics see the code and he says ''It SAYS the O2 is bad but is it?'' OTC has or had a break-out box to check circuits with a DVDM . It hooks up to the computer and you measure voltages and resistance with a DVDM. It can check grounds and open circuits. There are production change bulletins (PCB) that tell you about updated parts like head gaskets and head bolts.I think the company is All-Data. The videos are GREAT! Keep it up! A REAL mechanic can figure things out with even a paper clip!

[@SchrodingersBox]

Yes of course all that's true- but the question is: how would a scanner have been useful in THIS application? You have a cranking no start with confirmed cam and crank hall effect inputs. Exactly what PIDs would you have used to determine the direction given that starting point?

What do you hook up the paperclip too

[@rustynail9793]

Amazing. Loved watching the fast diag... I have a neat test light. It shows voltage and has a red/green light depending if you are on positive or ground. Watching you make me want to fix something. A guy came to me late one night and asked if I could fix his brake light. I don't have a garage but told him to get a brake light switch and come back in the morning. We will do a proper diagnoses before putting it in. Went thru and found out he pulled the fuse to the brake light cause the horn was on the same circuit. So it wasn't working neither. Found out the reason the fuse was pulled was because the horn had a short on the wiring. So I put in a fuse. Got his brake lights working and told him not to hit the horn button and if he wants we will figure it out to. He had work that day so couldn't check on it. He wants me to put brakes on it so maybe I'll do the horn then. Who knows. I hate spending money on stuff I don't need so I try to be a part of the 2% club... My dad had an issue with his headlights. Took his van to a garage and they said it needed a new steering column. 300+ dollars later and still the same issue. Got the van back and I was like 16 or 17 but I tried. I went thru the wiring and found the wires at the dimmer switch was bad. It was a 90s caravan so the switch was actuated by a rod and the switch was at the very bottom of the column. Easy access. I fixed it and no issues till the van gave up... Mechanics who are parts changers give the rest a bad name.

I, did notice I've got 3 fault codes poping up on the cluster gauge. so, I'm. going to replace the electric fuel pump sents I ruled that out.) one, problem can have many factors.👍

Most of us know why shops will install a new pump (or so they say) and charge the hard working person at least 350-500 bucks. all they might do is fix the wire like you did. I have been a long time veiwer of your channel so thanks...... With that said I am redoing my sisters brakes because of a pinched brake line which led to a stuck caliper (work performed at a local shop) they said her brake pads were on backwards.... what horseshit, so i am putting in a new front brake line and new caliper because the boot in the caliper melted. And then charged her 650 for a rear main seal...... guess what.....yep still leaks like before. I was going to do it for her but I had my back fused and now I am kinda able to work on things right now. Now less then 6 months after the repairs I am doing it all over again, the right was by myself. If your not careful you will be had!!!!!! and most people never know they were cornholed......

Good honest people. I learned a few thanks 😀

[@selfproclaimed3112]

You're an awesome mechanic. My hat is off to you sir

[@jasonmcnamara2079]

I would've slipped you a fifty for your time and effort

[@SchrodingersBox]

You'd be amazed what I've been offered....

[@jasonmcnamara2079]

Working in my own business also in a trade area I've learnt that my time and expertise was worth at least something, it doesnt have to be a full blown invoice to people but at least a few bucks, people don't mind and alot of the time they actually said to me it was worth more and gave me more, especially older people. Those people always come back to you for more great service too.

[@danwood4312]

Tipical stupid guy, you haven't been able to fix that truck, but you still give advice how the job should be done! What a looser!

[@elissacousland44]

I work for a vintage car part company, selling stuff to gearheads all day. I'm privileged to get to pick the brains of several brilliant guys who operate as techs in our company. I, however, am not one of them. And I'm trying to diagnose a crank no start by myself. It's currently 34⁰ and dark outside, I have no tools, garage, or lights, but I do have a few bits of knowledge going for me. I have tach readings during turnover. I have an easily turning engine that just won't grab. I have a 3/4 full tank full of gas (which automatically means its the fuel pump, right? Lol) and I have fuel pump engagement, as I can hear it running when I turn off the ignition. Tomorrow, if my prayers and blood sacrifice to the mechanical gods go unanswered, I'll check terminals and cables (hard to do in poor lighting) and check fuel pressure. As soon as I find the rail. One of my work tech buddies thinks I might have low voltage as my lights dim just a bit when cranking. I think it always did that anyway, but of course I don't remember for sure. I don't want it to be a battery issue as it's only a year old. If it is a battery issue, and not just the cables or terminals, I'd be worried about the alternator having caused it. Equally worrisome is if it's a cam sensor. Long story short, I can't really fix any of this by myself regardless. I lack the tools and the know how. But I'm hoping beyond hope for something not expensive, and not cascading. 🤞 Thank you so much for this video. I appreciate all the knowledge that you've shared.

[@diriazi]

You're a great guy and very smart. Thank you.

[@ashgall8118]

One of the best vehicle analytical videos I have seen. Great Job and thanks for the tips. I have definitely subscribed.

[@SchrodingersBox]

Awesome, thank you!

[@pedromorenoiii2641]

Thanks for the video! It's very informative.

[@ghtmedia3460]

3:36 Honestly.. Very next thing I would have done is give it the ol' liberal 5-second spray of either BPC thats Brake Parts Cleaner OR Carb Cleaner OR Starting Fluid whatever ya got (i try to alternate buying 2 cans BPC and 2 cans CC as I hear CC is stronger and BPC evaporates quicker and is still strong.. idk, that sticks from memory) and if it starts.. tells me a lot. If it doesn't I look for spark by pulling a plug wire and getting it on a screwdriver then I just have to find a way to see it while I turn the key.. These two things tell me a LOT about whats going on. Watching this for the first time so I want to see what you do. You have excellent videos by the way.

[@ghtmedia3460]

^In the air intake and past the throttle plate, of course. I forgot this is the Internet so someone will say, "WHERE?" But, of course. Pardon me, do you have any Grey Poupon?

[@ghtmedia3460]

4:39 :good: :good: :good: Okay! I love you, man. Seriously thinking about getting up and showing you my Corolla.

[@brianshanahan3878]

Awesome job, great video and great explanations!

[@steveg5576]

Gotta charge something my friend for folks to take you seriously. It enhances your position, not the other way around. All of us learn sooner or later. Good vid - from a fellow tradesman.

[@SchrodingersBox]

+steveg5576 I am not exactly following why charging people would be necessary to be taken seriously. Why is quality of work and competence of method not the criteria? ANYONE can charge for work.

[@Ctrl1u]

What a great mechanic!!!

[@alcyr5655]

Learning more with every video I watch. I was just going to throw a new cam, and a crank sensor at my sons 93 Grand Prix. What a waste of money, if it turns out to be the coil pack, or a bad wire. For sure the process of elimination, is the way to go.

[@SchrodingersBox]

Good for you!!

[@franklopez2846]

Hello sir. I watched your video where you said you were 'such a princess', lol, and liked how you fixed the car. Now I found this video somehow and wow, let me tell you...You are really a BOSS! It would have taken me weeks to find the problem. So here I am with my car I have been fighting and struggling to find what is the problem. Is a 2002 Nissan Sentra 1.8L and has a crank/no start condition, I checked and I don't have spark in any coil I am getting good power and ground, my fuel pump is good, I disconnected a feed and fuel squirted out, I replaced a crank sensor, I don't believe is my starter. I discovered that when I crank it the battery goes low and after awhile it dies. So I charge it and check everything again. What you suggest could cause the problem, could you please advice me with any suggestion?? I appreciate it, thank you!

[@SchrodingersBox]

If you are getting good power and ground at the coil and have no spark, what was the reason for replacing the crank sensor as opposed to the coil? Not sure I follow that- did I miss a data point?

[@franklopez2846]

There was no point in changing the crank sensor? :( Where my car broke down, some people came to help me (nice people) and they also checked for spark, nothing, and sprayed starting fluid and didn't start so it is no a fuel issue. Now I haven't, however, checked pressure at the injectors, is there a possibility is an injector or there is no point in checking at this moment? Yeah I suspected the coils but they said it could either be a crank sensor or cam sensor so I thought the most logical would be a crank...so I replaced it but it was pointless. Can you please advice me what could it be? Coils, alternator, switch, or just a better battery? The one I have I got it new about a month ago. Thank you

[@franklopez2846]

And also, is it normal for all 4 ignition coils to go bad? Or there might be something else making them go bad? Thank you, good sir.

[@SchrodingersBox]

Frank Lopez Why would it be an injector issue when spraying fuel in TB didn't start the car? Plus nyou just said you have power and ground at the coil- but is there signal as well? You don't have enough data yet to make any kind of conclusion. Validate power, ground and signal at the coil and if confirmed the coil is bad. As for all 4 coils being bad- I would far sooner suspect there is failure of power, ground or signal than all 4 being bad. You need to rule out electrical FIRST!

[@franklopez2846]

I actually just realized I didn't check the signal. I did, though, checked for Hz with the red lead and it read 0 but connected to the battery gives me about 5.99 Hz, is that right? Am I doing this right? In case it is bad signal, I am starting to think is a bad pcm. How can I also be certain is a pcm? Thank you for your time. I am learning a lot from your videos.

[@rjaye2785]

Your kind does not come a dime a dozen. Good job and a good friend to have!

[@robertwillard8011]

incredible job. thank you!

[@ribbone1975]

Nice to see diagnosis to the last option available. Nice to also see a diy'er do it.

[@KeithSWD]

Wow! Amazing stuff!

[@1Ronin187]

$100 for your time and another $50 for picking up and you are a great guy sir. UP, and SUB.

[@AngieMusicArt]

You are just brilliant!!!

[@findvoltage]

Im astonished you dont have millions of views on each of your vids, how many times have i heard of people taking their cars onto the shop to have a similar thing happen to them from a 'mechanic'. You Bossed this diagnosis like a champ Matt, you da mang. The Mohammad Ali of diagnosis.

[@SchrodingersBox]

Hahaha you mean I used to be the greatest but now I'm dead lol!!! Thanks man. The truth is most people just want to see how to replace a starter rather than learn how to diagnose if you need one. The fact I don't have millions of views means I am reaching the right audience, as far as I am concerned.

[@findvoltage]

Sad about the greatest (Ali), but i think your right up there with the best of them regarding your abilities. The internet shall help alot of people reach the top of their game. Your not dead i can verify that. haha. thanks for your efforts Matt, i have learned how to learn better as well as become a better tech for your wisdom. much appreciated..

[@SchrodingersBox]

Peter V Lol never thought of it that way but you are correct about the haters actually wanting to be me. When I get a hater with a successful channel I'll probably change my attitude lol

[@SchrodingersBox]

Peter V I am not a professional. I state that repeatedly. When have I ever tried to present myself as such?

[@samirpatil1238]

Also... ur are an honest adviser. kip up. cheers mate

[@Iloveyhwh_1974]

You’re good. Very good. I’m trying to diagnose my 04 cavalier with same issue. I’ve got power to fuse box and relays. Crank no start. No sound coming from fuel pump. I’m about to check the wiring at pump.
