![How To Test and Diagnose Relays and Wiring [4 & 5 Pin]](/img/tr.png)
"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 (:
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.
as an master tech in the past, I approve this mans method. great explanations, demonstrations and final repair. bravo good sir.
Damn, didn't charge him and he even offered to pick him up!! Now that's something you don't see everyday... Good job, son!
If I really wanted to diagnose it like a boss I would just tell my employee to do it.
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.
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.
+gereral1 Thanks bro... hey how's the grandkid? Like 2 years now?
Merritt 1 year and a bit.... thanks for asking
+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. :-)
Stambo What would you have done differently?
+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.
Open your own school. Thanks!!!
I sort of did. www.Schrodingersboxqm.com.
FREE OF CHARGE!!??!! PICK YOU UP IF YOU NEED A RIDE TO COME GET YOUR CAR??!!?? You are doing gods work my friend.
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✌🏾
Awesome thank you!!
I like trouble shooting. I need to learn and improve the skill. Thanks for showing and sharing your valuable knowledge.
'Expeditiousness'...great word.
Thanks a lot. I have 3 citroens and I do mechanics very frequently here at home. I am learning a lot from you. God bless you. Muchas gracias. Tengo 3 citroens y hago mecanica muy frecuente aqui en casa. Estoy aprendiendo mucho de ti. Dios te bendiga.
good job no prob diagnosis and no charge u a good man
I would've given you $20 - $40 just for your awesomeness.
I’d give dude a whole buck. To me dude brought my car back from the dead. FOR FREE
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!
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.
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 UA-cam. 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
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.
That was sweet "no charge " need you in my area. Nice video
This is a servant of God 😇!!
Thanks for the video! It's very informative.
I have an interesting one, car (00 Park Avenue) randomly (very randomly) will not crank, while checking things over i noticed that with the key on (not in crank) i was reading 12V across the relay coil which made me scratch my head. In this vehicle the ECM completes the ground for the starter relay, with the key off it was open between coil and ground, with key on there is ~8k ohms resistance and near 0 ohms cranking position. None of the other computer controlled relays exhibit this reading, they are either open or ~0ohms depending on the commanded state. Has anybody run across this and am i wrong assuming that there is a problem with the ECM most likely causing the random no crank?
To clarify, i did remove the pin from the ECM connector and checked resistance to ground there as well and got the same ~8kOhm resistance with the ECM powered up so that should rule out a wiring issue.
Not a bad guy after all, why would a thinking brain give this video a thumbs down. wonderful video buddy
Great stuff man! I enjoy watching you diagnose.
The first thing I alway check is the fuses, nice video.
Well... he didn't say certainly... lol... (and the comment was made before he remembered the owner telling him about the recently replaced fuel pump...)
Hi, 🎉 if you could tell me.. . .im working on a 08 Toyota camry that ran hot , the car belongs to a fier man in Houston 😂❤ the radiator berst so i changed it for him along with spak plugs and a new crank sensor after it dont start it still didnt start i looked for a spake for the over head coil a bady spark came about every 2 to 3 seconds what can i do the help a good person out thank you for you patient and time.. .
Awesome video, honest guy!
14:00
I would've watched the basic wiring part.😁
Why can’t I have a friend like this in my life!!! 🥺😭😭
Cause you used that damn 🥺 emoji lmaoo
Now you're what I call a customer friendly mechanic rather than a rip you off mechanic. I'd donate some money to you just for your time if I were the guy that owned the vehicle. Too bad there aren't more of your type around.
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.
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.
^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?
4:39 :good: :good: :good: Okay! I love you, man. Seriously thinking about getting up and showing you my Corolla.
You are an honest and smart mechanic, you should have at least charged him $50.00 which would have been well worth it. I don't mind paying a mechanic his normal rate, but not when they fail to do a good job!! UGH.
I really like this guy, I like how he goes around and looks for the problem and not just guess and changes parts to see if it'll wok. You are a real mechanic buddy. Great Job. Were are you located?
Glad you enjoy it! I am located in Denver. I appreciate the compliment.
@@SchrodingersBox I might have to move to Denver just to have a reliable mechanic lol thanks for the vids man
So much tension... Gone after watching just a few seconds I knew I needed search more. Great job, you certainly are a 2%
God Bless You! Love from Fiji! you are awesone! i m an ameture in da field and i find ur vids very explanatory and very basic and fast approach! but here in Fiji we have alot of Toyota's but i think i am going to adapt ur approach to problems! thanks bro!
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.
I really like this home mechanic, NO BS, just straight talk.
8½ years later & we are STILL watching. 👁👁
wow, I've been watching your videos and you are a very smart and knowledgeable guy. Thanks for these tutorials. much appreciated
Hey I like your videos,simple and no need for expensive equipment ,fixing my central locking on my RX8,I know how much you love rice burners,lol.
Good video Matt! Even an old school wrench turning relic like me can enjoy watching these!! Thanks.

incredible job. thank you!
Ok, so the update with my car was that I really never found the problem to my car but my dad over rode everything as far as the problem. The alternator was good, the battery was good too and so was the starter but the car STILL wouldn't start so what he did was installed a wire to the solenoid and the battery and installed a push start button to start the car and fortunately it worked!
In that case the problem is now obvious, right? Since it works with the bypass....
There is a lot of knowledge that goes into fixing cars and sometimes a lot of expensive tools are required. Techs don't get payed for the time they work and if they do it's peanuts with a commission added in to try and make up for the peanuts. But most places it's flat rate pay for the technician (basically piece work on a clock). The entire auto repair industry is designed in a way that does not promote quality repairs. The pay plans promote Half-Assery, puts the technician on a time crunch for everything. It's in part the customers fault as well as a lot of shady repair facilities everyone wants it done cheap and fast.. Cheap, Fast, and Good. I tend to find that you can only have 2 out of the 3.
Yes it does suck. Customer should not have to suffer because of this. But until people are ready to pay god money for good work. Your likely to just end up with people throwing parts at your car. End Rant
+Auto Fix Pal You get what you payed for:) I went for a job interview to a garage and the boss told me they want the job to be done fery fast and very good (they are cheap too). That was exactly my thought - you can have all 3. I didn't accept that job offer.
+Gregory May I don't blame you. I don't think Any good technician that knows their worth would take that job.
+Auto Fix Pal I don't know how much "god" money is, but it sounds a bit too pricey for me.
+Mike Osvold "good money" is what was supposed to be there. Thanks for pointing that out.
I feel you man. We get paid jack shit, and are always rushed to get stuff done. I'm not saying there isn't hack mechanics, there are tons of them. But the blame really lies mostly on the system. People will never want to pay high prices to get their car fixed, like you said they want it cheap, fast and good. All you can really do is open your own place and build a customer base by doing quality work or get hired at a place that already has that reputation. I'm lucky with that, boss is chill, not always rush rush rush, it's more like get it done right, not fast. Makes for a much better work environment.
You are just brilliant!!!
[thank, you for you're video. I, have a 2004, x. type 3.0 jaguar. I, don't have a no crank and a no start. so, what I did was to take the starter relay out of the fuse box then use a jumper wire to jump over the starter so then the jaguar starter turned over but would not start. so I then shot 2 sprays of starting fluid in to the air box then the jaguar started on the starting fluid. so now I need to drop the fuel tank and replace the electric fuel pump inside the fuel take. 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.👍
Thank, you.
Easy step by step explanation from simplest to difficult , VERY knowledgeable, and willing to share with n help others ...on top of that honest.
You sir, are a God-sent genius!
Keep doing what you do it all comes back in due time.
A Gidamm BOZZ and GOD-Send iz what You are Sir Before and After All!😄👍🏾
You ARE a BOSS and a credit to the entire DIY species! Love your video style, straight to the point without too much fluff. Good job! ;-}
Ha- the "DIY species"!!! I wonder what the Genus and Phylum are? Chordata HomoMechanicus?
Awesome job, great video and great explanations!
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...... Just my thought, sorry for being long winded but there are preditors out there. It was nice that you offered to pick up that guy after you went to King Super....LOL
+Michael Bowman no you minion, I did not install the brake pads, and besides how in the hell is that even possible. although you would probably know. Go pound sand you mental midget.....
+Michael Bowman your lack of intellect isn't my issue
Michael Bowman Take it easy on each other for Gods sake!
Fantastic video =P
Regards
how to diagnose a car like you! thank you for all your help man
Awesome channel Subbed ! 👍🏻
Good honest people. I learned a few thanks 😀
After watching...I wonder how many of the “thumbs down” watchers got here .. Mr Schrodinger ...another Excellent video for the doityourselfer.....
Wow that was a good video, one of the best I have seen for DIY, thanks man.
Hi Matt you could have put your test light to battery positive and probed onto terminal 87 if your test light doesn’t light then there is no continuity on the fuel pump feed wire ,your test light will light on this because if you have continuity on the feed wire to the pump it will go to earth out through the pump, that is if your earth connection is good it’s one quick test you can do before going under the vehicle
Thats true- could have certainly done it that way for sure.
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.
+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.
Had a 2010 nissan navarra ST-X diesel with a crank no start. D40 Common rail diesel engine. Noticed no check engine light on the dash. No comm with our scantool. Found no power being supplied to the ecu. Checked fuses and relays. Was going to check the ignition barrel but customer didn't want further diag. Also found an online thread at aussiehelp.com about a problem with the power distribution box about corrosion on the ignition relay.
Wow! Amazing stuff!
Thanks for this video. It's good to see different approaches.
awesome video I'm just watching to learn 👍
Hi. I have skoda octavia 2013 and vcds scanning showed mechanical fault in intank feul pump twice. First time. 10061 - Fuel Pump
P3043 00 [167] - Mechanical Malfunction
MIL ON - Not Confirmed - Tested But car is still running. Second time it showed this error. 10064 - Fuel Pump
P308D 00 [096] - RPM too Low. Does this mean that I must change feul pump soon as possible before it stops?
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.
Awesome video! Troubleshooting 101
You were swift & thorough. It's all process of elimination....and know-how of course :)
Everyone is in business to make a living but there are way too many parts changers out there ripping customers off.
You still should have charged a Diag fee since the customer didn't bring it to you in the first place....fair is fair. Personally I wouldn't have had a problem with that & appreciated your honesty. Cuddos man! I Subscribed, like your methods & explanation process
'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.
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.
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.
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!
Don't forget the famous there's a bolt back here I can't show you, but, its right here. . .
You are awesome for not knowing isuzus. I have a isuzu trooper with the same problem. After watching your video you brought my hope level back up. Thank you for posting. Wish me luck I sure need it.
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
I would've slipped you a fifty for your time and effort
You'd be amazed what I've been offered....
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.
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!
The depth you go into is nice to see !!
Watching you crawl around under that vehicle made my back ache. I'm going to buy you a taller garage and a vehicle hoist, well after I win the lottery I mean.
Did you win yet?
Matt
That power probe is a good tool to have
Made sure that the fuel pump was working
😇😇😇
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
Same here!
@ Schrodingers Box, Once again... your videos are awesome and informative.
You're a great guy and very smart. Thank you.
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!
Thank you man! Thank you. Your direct and sensible methods are top notch, your gift of teaching real-world valuable skills in such an efficient fashion will help more folks than you may ever know! We need more in the world like you, and perhaps things wouldnt seem so confusing at times. A lot of things in life are intentionally designed to frustrate us. You my friend are the antidote to such things! Rock On....
That was fun. I have basic tools and working on basic/DIY knowledge.
+wyattoneable Now you can add no-start diagnostics to that list!
You sir are amazing! Good job!
Nice work Matt thank you for teaching me very special man thank you
Great job, Matt! My favorite test was the starting fluid and paper clip starter bypass test. Beautiful and simple!
I think the test light should have spent some more time at the relay box...you can definitively check both control and load side in 2 seconds :)
+motoYam82 Yes no doubt test light could have been used in all applications on this one. It's funny- I assume you have your testlight right on the top of your toolbox to reach for while I have my DVOM there so it;s what I grabbed!
What do you hook up the paperclip too
NO PARTS NEEDED..!!!!!!...........mate you should be stuffed and put on the mantle piece...!!!, here a customer like the ISUZU would be given a $ 1300 bill and a bucket of VW parts as proof of repair. Thank you , great vid.
Matt, great, tutorial, educational, entertaining, and informative video. Exceptional work, keep it up!
Good Lord....!!!! that guy is like a WOW.......!!! his utter confidence in a fact that his is a master does it all...... thumbs UP!!!
You play that fusebox like Curry can shoot 3's.. wish I can do that
you can .. grab a ball
really a good diagnosis detects messy damage problems that can't be started
Good learning for me
Thank you
one time my car didnt start and after about an hour of fooling around i figured out the gear shift wasnt fully clicked into park! dope!
Wow dude.....nice guy! Your like me....bend over backwards for people. My mechanic, who over see's me mechanic nightmare fixes on my 1999 Nissan Frontier. I just replaced fuel injectors and IAC under the manifold myself. So crazy of job for first time out. hehe He knocked my door this morning and needed me to help me tie, his tie. I came up with a whole bag of ties, gave him a new tie and tied his tie. He looked like a pimp, off to church! I said..."Thank GOD for all we are blessed!" The truck you fixed....he'll tell others friends too. I have a dead battery, after replacing the ignition distributor. That is how ended up here.... Always something.... haha
Also...
ur are an honest adviser.
kip up.
cheers mate
You my friend, are one bad ass DIY guy! Wish you were in my town! You don't, you would get sick of me picking your brain!! Thanks for all the info I am getting from your videos, I watch often.. You are a born teacher!
Thanks man! Glad you found the channel!
Shoulda told him to order you a pizza at least hehe
Just saw ur. Video u kick ass NO charge at all!!but still fixed the problem Wow that's awesome..Great person you are.. I would still give u like $50. Or something 👍🏼👍🏼👍🏼👌🏼keep up the great work.. and thnx for posting up videos
Man I am very impressed by the things you do instead of just throwing in parts with assumptions like some mechanics. I wish I knew a mechanic like you that can be trusted. You're so awesome! I like the way you do work, we need more people like you!! hahaha
Thanks man, whatever the hell your name is lol!!
@@SchrodingersBox hey i have a 07 navigator and its having almost the same issue. so far ive followed your steps. in conclusion ik im not getting any fuel to the car and before that i actually checked my fuses in which i discovered that some of my pcm sensors including my fuel pump diode arent getting power. My car started temp. after spraying starter fluid and then died. Please lend me your advice. Thank you so much!
@Schrodingersbox
6:21. Are 30 and 87 the control circuit? I thought they were secondary/ switched/ load circuit. As opposed to the primary/ signal/ control circuit
Thank you for your Electrical Diagnostic. I've swapped out so many parts, including the fuel pump today and still, no joy. At least the bed is off which may help me find the open circuit :( w/ my new voltmeter. 2500se mazda 2000- I'm a DIY and could use a basic rewiring repair, so if you have a link for me, really appreciated.
What a great mechanic!!!
Parts changers absolutely will thumb down this video
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!
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?
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
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.
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!
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.
awesome how u didn't charge and worked on it. now that's a bad ass diy
No No you are doing it all wrong Matt. This thing definitely needed a new F-pump and a couple of the injectors were bad from what I can tell over my Wifi connection. Changing out a Fuel relay is a given "no brainer", also just for good measures I always throw on a new-used set of windshield wipers for the customer.
+FDSeoul San Diego Lol- ok true story-- had a person who brought car to shop. They actually showed me shop's receipt: the Shop charged $90 diagnostic fee for an hour on a MIL on a P0171 and "unable to find issue- reset check engine light".
But under recommended services it said "Brake pads worn- recommend replacement". The guy couldn't figure out the engine problem but he had time within an hour to lift the vehicle and check the brakes????
I didn't know you were allowed to give the car back to the person and say "unable to find issue" LOL thats slightly ridiculous
Oh yeah! Like a boss man. That was like 2mins fix. 👌🏽
And yeah I like that old diagnosing method, get to enjoy the challenge. 👌🏽

My local mechanic refuse to solder ONE wire - parking light was off. He saw wiring torn, then he said "You have to go to some car electrician because it is CAN BUS". Then I found on the Internet wiring diagram, and soldered it my self. The worst thing is that mechanic was my former phisics teacher at high school. He was rough as a teacher but as a mechanic is rather like his bad studens.
