What I want to know is who the hell is giving you thumbs down. You are by far the best UA-cam mechanic, super work ethics, extremely knowledgeable, and simple to understand.
I really like the honest representation of the little problems you ran into when installing the new starter. A lot of guys would have just zipped right through that without showing the way things can get in the way like wires and heat shields. That was real!
I like how you show what is actually like to work on a car. Trouble getting starter out. Dropped flashlight & tools. Thanks for keeping it real. Great job
A simple Test light I feel is arguably the number 1 best and most useful tool for finding electric issues. When used correctly by a skilled pair of hands, it gives 100% accurate, undeniable, and consistent proof to locate an issue using very simple and quick techniques. By itself, it can locate probably 75% of all electronic issues a tech will encounter in the field.
Funny thing about throwing parts at it is that the first and second thing "thrown at it" would have been the battery then the starter with absolutely no trouble shooting.
What would of threw me is the fact that the truck started when you messed with the ignition switch , it started and the history of defective GM ignition switches. It all worked out good - relays, fuses, etc. needed to be all checked. I have been a mechanic for 40+ years and just retired 3 days ago and still enjoy your videos. Keep up the good work and the videos coming!!
Man this mechanic is awesome and very well spoken!! He doesn't feed a ton of useless shit and is straight on the point,BEST and easily understood mechanic on UA-cam!!
Wish we had more honest, reliable and humble mechanics like Eric. Did I mention patient. Because his patience is what saves his customers money otherwise he'd be changing numerous parts instead of taking the time to methodically diagnose the vehicle. Thanks Eric
Jamie Torfason, my kept doing the exact same thing and I cant figure out what it is! After messing with it so much now it doesn't crank at all, did you get it figured out why it would run for only a second and then shut off?
Eric thank you for taking the time to put these videos out. You did this job the right way. Sure if your stuck in a situation where you need to get rolling down the road, then tapping on the starter is a quick fix to get going. That being said, it's great to see that diagnosis from switch to starter and how to follow diagrams to assure everything else is in order. Thanks again for being our teacher and keep these videos coming.
I wished all mechanics were as good as you. You even put Eric the Car Guy to shame with your thorough diagnostics. You make damn sure the problem is what it is before you repair. That is what I like so much about your channel. Thank you for all you do.
Eric your videos are phenomenal, you definitely present right way of troubleshooting and diagnosing the problem in a very clear and systematic approach. I have learned quite a bid watching your videos they are very educational and informative. Many mechanics out there just swap parts till the issue is fixed not real techs. Keep up the great work you do contribute massive knowledge to the guys like me and others. Thank you for the great lessons you share with us.
This video saved me hundreds of dollars! I followed your diagnostics steps and replaced the starter motor. Sure enough, my GMC 2500HD started right up and she is back on the road. Thank you very much for your clear instructions!
I am so easy to please. Every time Eric makes a machine sound like that I smile with happiness. My favorite was replacing _one_ injector out of six, and boom, the engine went from sounding horrible, to sounding as smooth as glass. Lovely.
Eric,,, another Great Video... I'm a newbie at viewing your "Expertise"... But being a 71 year old that's alway's worn glasses since I was 3 yrs old,,, they have saved me many time's from getting "crude" in my eye's,,, I'd like to see ya' wear a pair of "Safety Glasses" when you are working on overhead projects...

OR... Safety Squints Engaged! JK... after a few times of totally being put off my work and running to the sink to try to wash some crap out I dont play around anymore.
I've been beating my head for weeks about my 2007 Malibu. i thought it was the battery so I replaced the original AC DELCO, just like this truck, but it started acting up a month later then got more frequent so I got a much better battery , the first was from Walmart. And it happened two days later so I got rid of my subwoofer because I thought this was the problem. some days it'll start other days a no go. same exact symptoms.i thought it was only on days. that it was very hot. that's when I first noticed. and my cars black. for a while if it didn't start and I jumped it with another battery it would fire up. I'm at 110000 miles. but I watched every second of this video and I learned so much. I'm convinced my starter is the culprit. unfortunately I'll need to save the few hundred $$ to have a shop fix it since I only have basic tools.but thank you so much. I watched the switch from hell and was convinced it was the ignition switch. but now I know it's the damn starter thank you a million times
My 2004 Silverado did the same thing since the day it was new. Occasionally it would not crank but no indications of low battery. Sitting in the cab and trying over and over again would usually result in a start. Replaced Starter relay. No help. Thought about the switch but decided against that. finally put a jumper with a lamp on the starter terminal and ground and waited for it to fail again, which didn't take long found good power all the way to the starter. Replaced the starter. No problems since then, been over a year now. I had this to the dealership four times during warranty and they were no help at all. Great video as always! Thank you!
I took my 81 Chevy with a 350 diesel (under warranty) to the dealer years ago. The starter would crank and engine would start. But, the starter would not disengage. They said it wasn't happening, and tried to tell me one of the batteries had a weak cell. It only happened occasionally and often when my wife was driving it. Long story short they refused to pull the starter. When I installed new batteries before the next winter it happened more often. So I parked across their bays only entrance and sat in the waiting room. They agreed to pulled the starter and it had a cracked housing. Dealers often don't want to take the time to diagnosis a problem. I get that they have to weigh what they are told by clients, but they should listen to them and consider the possibilities. The fact that they had rewritten the description of the problem I left when I used the night drop was especially irritating. Another dealer changed the fuel injector pump and left a wire dangling because the new pump didn't need it. It took out the fusible link to the glow plug circuit and he told me it had nothing to do with what they worked on. I was a radio repairman in Vietnam and an industrial technician at the time. I am familiar with automotive electrical circuits. I asked him to explain why they left the bare connector and he continued to BS me.
South Main Auto Repair: Thank you sir for taking the time to instruct and demonstrate troubleshooting procedures. This starter vid reminds me of my starter wrestling match on a military vehicle years ago(1960's) and the "never assume" lesson I learned. The starter must have weighed close to 60 lbs or more for a V-12 engine, containing slip clutches set to 850 Ft./Lb of torque, designed to spin out(so as not to bend connecting rods) if excessive fuel was on top of a piston. I did NOT check starter or solenoid with batteries BEFORE installation. Once installed and wired-I engaged the starter switch-nothing? All checks were conclusive-the new starter solenoid was defective!! The entire starter had to be replaced(again) as a complete unit down in the Eng. compartment at over 100 deg. F. I still check new starters on a bench or vise BEFORE installation... changing gears...I was invited to climb into the cab of a large city Fire Truck. As an emergency vehicle, the FD could not afford a solenoid failure so the engine had a MANUAL starter switch which was actuated by a rod or shaft that penetrated the floorboard adjacent to the driver much as a gear shift.
Just used your video to help me diagnose and replace the starter in my 91 year old grandfathers 01 Silverado. Thank you so much for your detailed video. You definitely have a new subscriber!!!!!!
I really appreciate the way you go through the diagnostic troubleshooting to resolve the problem, explaining the reasons for each test point and expected result. I agree with the other comments. You are a true mechanic and not a parts swapper (at customer expense). This is why it is worth his or her weight in gold to find that REAL mechanic. That will save a customer lots of $$$$$ down the road. Great videos. Thank you.
You are a true pro. Anyone can throw parts at a problem, which is never a good idea, especially when dealing with intermittent ones. My 04 Yukon is driving me crazy right now with an extremely intermittent no crank. Can't get it to happen long enough for a good diagnosis. Already replaced switch, which is a high failure item, and relay. Getting ready to throw a starter out of desperation.
Though the switch was strongly suspected, using the "split-half" troubleshooting method, as you did, of starting in the middle of the circuit is usually the most efficient way. Excellent video! Thanks for sharing!
Thanks Eric. I am glad you didn't fall victim to the pattern failure of the GM ignition switches. It would have been easy to do considering you changed them out before. Your video is a good reminder to test your suspicions before swapping things out. Thanks for taking the time to send out another good video.
I probably would have checked for power at the starter solenoid myself after checking at the fuse but there is nothing wrong doing it the way you did it. Everyone has there own procedure and at least you didn't miss anything along the way. Some of your viewers might have learned something as well. Nice job Eric
You just solved my problem. I was at Lowes about an hour ago trying to start my little 2001 S10 for around 20 minutes. I don't have many tools anymore ( long story) so I go the "change parts til you find it route if it don't break the bank first. I have a metal bar in my neck now and just can't crank my neck around anymore so I'll let my guy replace the starter and solenoid for me. Honest mechanics are hard to find and I found a GREAT guy like yourself. Long story shorter, you have a new subscriber ! Thank You for helping so many of us !! (407 dislikes ... are they KIDDING ?? must be those armchair do nothing experts ? smh, maybe they just hate their own life ?? sad .. )
Thanks! Had the same problem in my 03 tonight. Thought it was ignition sw.or neutral/park sw. But tomorrow I'll test starter, I tested the relay and fuse already. Same exact symptoms but my battery is new. I'll bet money I'll be changing my starter. 245,000 miles on original. No complaints! That video was exactly what I needed. Good job on it, I'll subscribe.
I've been watching your videos for a while now but I never came across this video which was extremely helpful. I've been having this exact problem with my 03 suburban and now I can finally fix it. You're a lifesaver!!
I really like the troubleshooting in these vids. I spent most of my time in the IT world during troubleshooting. Making assumptions can lead to delays and repeat work. I had 2005 GMC 2500HD with Duramax and the dual factory batteries lasted 9 years. I think the heat wrap they put on them really helps extend the life. I put in new batteries in June 2014 and then traded it in a new RAM 2500HD with Cummins in July. Oh well.
This was well done and helpful, and that's why among all the videos about this issue I am posting the following comment: If it is the battery as it was with mine, you have to actually INSTALL the new/good battery, NOT just jump it - that will not work. After viewing a dozen videos and forums that's what I finally found out from my shop. I believe them because any other problem with the system would have cost more to fix. Plus it did work. The explanation from the shop is that it has to do with the computers and complexity of the charging system, and the need for direct cable connections. Jumper cables do not provide the necessary power feed.
Had that same problem with my 2005 Trailblazer. Did the exact same thing. Tested the relay, fuses, & start wire to solenoid. Same as you everything checked out. Starter was a bit more a bugger to change out, my battery wire at the starter was a little corroded too. So cleaned and put some red battery terminal protector on it. Fired right up!
Great video, Eric! I always learn something new from your videos. I had the same issue with my wife's car a few months back. Lucky for us a tap on the starter with a wrench got it to start and she was able to get it home.
Sure did! Ran some test on the wiring with my dvom to make sure it was the started and not any wires. Wires checked out okay. Replaced the starter and have had no issue since then!
Most places here mechanics just replace parts if you need them or not.We got burned 2 times from a place here in Florida. Eric you are an honest mechanic
Ive been wrenching for over 40 years. I appreciate the TS you do as Ive been taught both ways. Either at the suspected component first or at the battery and work forward. Eliminates by positive test results.
Nice to see a mechanic who knows his craft. Cleaning terminals, knowing how to test circuits, properly torquing fasteners are just some indicators this guy understands how things work and what it takes to repair it properly. Remember just because we drive away doesn't mean the job was performed correctly. Details are important and unseen by most. Good to see a nice change.
I really enjoy all of your videos. It makes me appreciate a good mechanic who spends the time hunting down the problem instead of throwing parts at it. Excellent job. If I lived near South Main Auto you would get all my business. Keep up the excellent work and keep those videos coming.
Good diagnosis. Myself from experience, I would of went right to the starter, just for the fact that it seems almost everyone I have done like this, where it won't crank in the crank position and the lights go out in the dash, I always go tap on the starter/solenoid first then test for everything else. Any time I have done a switch is when its messed up and has to be broken in order to turn it so it can be released. But at least now I have seen another techs way of doing it and shared experience. Thanks.
My 04 2500 4x4 8.1L, 215k miles Avalanche draining battery when sitting for 2 days. I replaced battery without a test. Still draining battery to 0. O'Reilly tested with handheld, the battery, alternator and starter at the battery. Had me startup and his hh showed starter pulling far too many AMPS. Thus, starter need be replaced. You're testing is very thorough, teaching much. Thank you, for the lessons. I also watched your gauge cluster video. All very informative. I'll watch more of your videos. Its easy to see you can read schematics and know automotive electric.
Starting at the "wrong" end of the circuit did cost you a little extra time, but testing and explaining the different components and functions made this a very informative video. Thanks for sharing.
Thanks for the Help, before I bought a battery I watched the vid and saved me from buying one, it was the starter. Easy except the rotted terminals. Thank you
This was very helpful. I don't know why there are so many dislikes, I guess people just have to be negative. You did a great job on this troubleshooting video.
Very very nice and informative video. I like how you really took the time to diagnose the real problem before just throwing parts at it, too many guys do that waste so much time and money, I had a similar issue on my 2001, however, the positive cable on the starter was loose by about 1/16th of an inch, which aint much, but enough to not allow the truck to start!
Glad you worked through the circuit rather than jump straight to the starter. I'm having a similar problem on a Chevy van, and I'd like to rule out ignition or relay BEFORE crawling under the van in subzero weather and snow to check starter. Your video showed me I can check both pretty easily at fuse box.
As a retired industrial electrician I really enjoy you electrical trouble shooting video's. You have excellent trouble shooting skills. Your starting point logic was sound after getting it to start by playing with the switch. How the heck does anyone get nine years out of a battery? I have a 2006 Malibu I bought new and I am on my third battery.
+DC Rickerson Thanks sire I appreciate that. Not sure on the battery though. In our cold climate they do last a while compared to one exposed to a lot of heat and vibration.
DC Rickerson, Buy a better battery. Interstate Mega Trons in my truck and car. 6 plus years now in the car and no issues, just redid the truck. I've gotten 7 plus past experience. I am on the east coast, Phila, Pa. Hot summers and Cold winters.
Try the better Heat beater or Interstate battery, they are the only thing that wors for more then a few years here in the Southwest Tucson Arizona the heat eats batteries faster then a fat man at an all you can eat chicken buffet. Only good thing is we don't get that fine New York rust . :)
At my shop we work outside on the rocks. Keeps our creeper from rolling away. For a lift we use a big rock. We do great work at ROCK SOLID AUTO REPAIR. Great job Mr O. Thanks fer the tutorial.
"Scope on a rope". That cracked me up. Starting at the switch was good for the video because I learned a lot. Thanks for that. I'm starting to see a trend when ever your under a vehicle. Lots of rust on the frames. I guess NY winters are tough on cars.
@@SouthMainAutoso if the light doesn’t turn on when I’m testing the fuse while I’m cranking it. Most likely it’s an ignition switch problem. So I have to replace it then. My vehicle no start or crank btw
Great video. Teaches how to diagnose a problem. Keep up the good work. As a mechanic who gets paid to fix things, I can see the advantage of replacing the starter as a single unit. For the home mechanic, does it make sense to replace just the solenoid? I suspect the new starters come from China and I don't like Chinese parts. Often the new aftermarket parts have a much shorter life than the remanufactured parts from a few years ago (before China). I know when the voltage gauge on the dash was all over the place many years ago, I took the alternator apart and replaced a few parts (regulator) and it still works perfectly fine.
On my 2001 Silverado my original starter went out with no warning at all. Drove it to a job site just fine. When I came out to leave, nothing. Did the starter right there in the parking lot. Be VERY careful of the crank sensor and harness. I damaged mine because I hadn’t done that on this truck before. After doing the starter the truck cranked but wouldn’t start! Had to take the starter back off and rig the CPS harness to work just until I could get home and do the starter for the 3rd time! I will say 18 years of near daily use is pretty impressive for a starter.
Nice video. Who the heck would check the starter first after wiggling the ignition key and getting a no crank no start to start. You went about your diagnosis in a logical manner.
I want to thank you for all the great videos that you have put online for people that are working on their vehicles and don’t understand as well as you know as being an expert you’ve helped me many times when I’m searching for answers I want to tell you thank you
You did it the right way Eric. The ignition switch would be cheaper than the starter so in the unwritten law of mechanics 101 of throwing the kitchen sink at it till you find the problem,you would always start out with the least expencive parts,then work your way up to the big $$ items. As follows. Car wont start. Check fuses. Check relay,wiggle wires,check for corrosion of all wires ( naturally) then take a hammer and wack the starter .If it starts then you drive it to the auto parts place to see if they have a starter. Then you shut car off ( by accident) find out they dont have it at that store but the one across town has it. Go out to start car,no start. Hammer method no longer works. Call everyone you know,no answer.End up laying on parking lot in the rain to change starter,short out fuse by forgetting to disconnect battery. Finish in the dark only to find out battery is now dead,get jump start. Wave goodbye to all your helper friends that finally showed after you finished. Jump in car pull headlight switch only to find out the headlights and dashlights no longer work,its dark,the store is closed and no one is around. Oh and did I mention your cell phone battery died just as you started dialing a friend. Yup,one of THOSE kinda days.
I feel you on that ,I have a ex new York police tahoe at the shop with a hot soak no crank that I cannot duplicate, probably needs a starter but until I confirm its a no go
Tried both a scope and a midtronics tester with an amp clamp nothing off cranking volts were normal, 2 days with it, it never missed a beat even letting it run for an hour several times, he picked it up Friday no charge no parts replaced
I'm working on my son-in-laws 01 S10 4.3L Automatic. The truck was over heating. I had to replace the intake manifold gaskets. Of course you know what all that involves. After replacing the gaskets and put everything back together, the truck will not turn over, it was running before. All we hear is a click under the dash when the key is turned. I've checked the battery, its 12.4 volts. I pulled the starter and had it checked. It was good. Although the connector on the PPL wire broke, I replaced it. I used an OHM meter and checked the grounds and they checked out good. So did all the fuses. The only other things i have not checked is the P/N safety switch and the IGN switch. Good video, Iv'e got to check out your other videos, so I can figure this out
Great job and video! Ive been watching Eric O's videos for a few weeks now (found him thru an ETGC video) and really like the fact that that he is not only good, he is HONEST. That is the biggest 'lost skill' of today. In this specific case Im wondering if it was possible that the no crank was due to the weak battery. We never saw a test of the old starter with a new battery (or bench test of the old starter with bench power supply) and Id be curious to know that result. Thanks
+jeffscomp Yeah, you want to avoid the hammer bit. Starters have magnets in them, and if it isn't the starter itself, you'll crack them up and destroy the starter. Best to tap it with a piece of wood or a small deadblow hammer or something, not too hard.
you can hit a starter pretty hard before you break it, trust me, a dead blow or a piece of wood sometimes doesnt work, for example on my truck the starter locked up at work, went under there with my baby hammer and tappity tapped and nothing, it finally cranked over when i gave her the shit. didnt crack my case or anything. if you have any decent knowledge of vehicles you should test everything before you condemn the starter with a hammer. i always carry a test light with me. the joys of being a paranoid mechanic lol
Your AWESOME previous video helped me out with the 'Oil Pressure Sensor' and saved me over $600 now i just need to fix my no start issue, this video may not be the answer i was looking for.
When I went to work for Sears Automotive they sent me to school down in Atlanta, GA for starter, alternator/generator, and battery school. That was my first ASE Certification test....Next was alignment training. All this happened almost fifty years ago.
Thank thank thank you! Your first sentence was the fix. Bad switch. A little extra torque on the start and bang. Starts right up. Thanks for the showing the circuit work.
Another culprit is the Discrete Logic Ignition Switch (DLIS) Fuse under the hood. Great video that walked me through all needed checks for the exact same symptoms, but ultimately ended up being a corroded DLIS fuse (2A).
I just bought a 2003 GMC HD and have this eractic starting problem like ur talking about. You had stated that the battery was really bad in it the dash lights etc would fade out. I know low voltage takes out ECM, and other components and probably burnt up this starter. I was surprised that you didn't show us that it cured the problem before you put the new battery in. I'm thinking the dead battery probably had a dead cell in it. Your video really put me on track to go after my problem. I deal with helping truckers with ECM problems and troubleshooting. Keep up the good videos. I starting doing videos on L10, M11 & N14 Cummins engines 10 + years ago and get calls for everyday of the week. It's good to see other people sharing their knowledge with the rest of the world and seems to be growing more and more. Wish you were near by, I would definitely take my truck to you! Thanks Terry Chron. I let you know how this one turns out. The guy said it has a new battery and starter less than a year old. I was thinking the same as you, it has to be the ignition switch and or the relay which I had no idea was on this truck. I'm 68 years old and I hate working underneath trucks anymore. I hope it's the relay or ignition switch. Bur, youir video makes feel like buying a new battery and starter and taking a chance haha
Thanks you for going through process of elimination. I am facing the same issue with my 06 tahoe variant. I have replaced starter and ignition switch with no positive impact. I shall run the steps with light probe.
Your video is the best that I've seen. Too bad I didn't see it until today because last night I attempted changing out the starter. It's already been diagnosed as the starter. I wasn't able to get it out away from the bell housing. Your video is the only one I've seen working through the wheel well to get the dust cover and cables off the starter. I can probably remove the wheel to give me more space since I don't have a lift.
Damn good video and a great diagnosis procedure. I’m an aircraft mechanic and I don’t give compliments out easily ! Well done sir ! You taught me a trick as well ! Awesome job !
Experienced the same identical issue, as have many others from reading postings on different web pages and blogs. There must be an OEM issue with starters or the solenoids going bad. Troubleshot mine via the same approach and it was the starter too. Nice post. Good methodical approach. Thanks.

I'm at 110000 miles. but I watched every second of this video and I learned so much. I'm convinced my starter is the culprit. unfortunately I'll need to save the few hundred $$ to have a shop fix it since I only have basic tools.but thank you so much. I watched the switch from hell and was convinced it was the ignition switch. but now I know it's the damn starter thank you a million times
My 2004 Silverado did the same thing since the day it was new. Occasionally it would not crank but no indications of low battery. Sitting in the cab and trying over and over again would usually result in a start. Replaced Starter relay. No help. Thought about the switch but decided against that. finally put a jumper with a lamp on the starter terminal and ground and waited for it to fail again, which didn't take long found good power all the way to the starter. Replaced the starter. No problems since then, been over a year now.
I had this to the dealership four times during warranty and they were no help at all.
Great video as always! Thank you!
I took my 81 Chevy with a 350 diesel (under warranty) to the dealer years ago. The starter would crank and engine would start. But, the starter would not disengage. They said it wasn't happening, and tried to tell me one of the batteries had a weak cell. It only happened occasionally and often when my wife was driving it. Long story short they refused to pull the starter. When I installed new batteries before the next winter it happened more often. So I parked across their bays only entrance and sat in the waiting room. They agreed to pulled the starter and it had a cracked housing. Dealers often don't want to take the time to diagnosis a problem. I get that they have to weigh what they are told by clients, but they should listen to them and consider the possibilities. The fact that they had rewritten the description of the problem I left when I used the night drop was especially irritating. Another dealer changed the fuel injector pump and left a wire dangling because the new pump didn't need it. It took out the fusible link to the glow plug circuit and he told me it had nothing to do with what they worked on. I was a radio repairman in Vietnam and an industrial technician at the time. I am familiar with automotive electrical circuits. I asked him to explain why they left the bare connector and he continued to BS me.
South Main Auto Repair: Thank you sir for taking the time to instruct and demonstrate troubleshooting procedures. This starter vid reminds me of my starter wrestling match on a military vehicle years ago(1960's) and the "never assume" lesson I learned. The starter must have weighed close to 60 lbs or more for a V-12 engine, containing slip clutches set to 850 Ft./Lb of torque, designed to spin out(so as not to bend connecting rods) if excessive fuel was on top of a piston. I did NOT check starter or solenoid with batteries BEFORE installation. Once installed and wired-I engaged the starter switch-nothing? All checks were conclusive-the new starter solenoid was defective!! The entire starter had to be replaced(again) as a complete unit down in the Eng. compartment at over 100 deg. F. I still check new starters on a bench or vise BEFORE installation... changing gears...I was invited to climb into the cab of a large city Fire Truck. As an emergency vehicle, the FD could not afford a solenoid failure so the engine had a MANUAL starter switch which was actuated by a rod or shaft that penetrated the floorboard adjacent to the driver much as a gear shift.

Well done as usual. I look forward to each and everyone of your videos! Tell your helper .. well done too.
+Mark Scofield Thanks will do :)
Just used your video to help me diagnose and replace the starter in my 91 year old grandfathers 01 Silverado. Thank you so much for your detailed video. You definitely have a new subscriber!!!!!!
I really appreciate the way you go through the diagnostic troubleshooting to resolve the problem, explaining the reasons for each test point and expected result. I agree with the other comments. You are a true mechanic and not a parts swapper (at customer expense). This is why it is worth his or her weight in gold to find that REAL mechanic. That will save a customer lots of $$$$$ down the road. Great videos. Thank you.
You are a true pro. Anyone can throw parts at a problem, which is never a good idea, especially when dealing with intermittent ones. My 04 Yukon is driving me crazy right now with an extremely intermittent no crank. Can't get it to happen long enough for a good diagnosis. Already replaced switch, which is a high failure item, and relay. Getting ready to throw a starter out of desperation.
Though the switch was strongly suspected, using the "split-half" troubleshooting method, as you did, of starting in the middle of the circuit is usually the most efficient way. Excellent video! Thanks for sharing!
Thanks Eric. I am glad you didn't fall victim to the pattern failure of the GM ignition switches. It would have been easy to do considering you changed them out before. Your video is a good reminder to test your suspicions before swapping things out. Thanks for taking the time to send out another good video.
+Gary Habat Yeah it is a good thing we test instead of guess!
I probably would have checked for power at the starter solenoid myself after checking at the fuse but there is nothing wrong doing it the way you did it. Everyone has there own procedure and at least you didn't miss anything along the way. Some of your viewers might have learned something as well. Nice job Eric
+wysetech2000 I was just glad I didn't jump the gun on a switch ya know
Good tutorial 👍
You just solved my problem. I was at Lowes about an hour ago trying to start my little 2001 S10 for around 20 minutes. I don't have many tools anymore ( long story) so I go the "change parts til you find it route if it don't break the bank first. I have a metal bar in my neck now and just can't crank my neck around anymore so I'll let my guy replace the starter and solenoid for me. Honest mechanics are hard to find and I found a GREAT guy like yourself. Long story shorter, you have a new subscriber ! Thank You for helping so many of us !! (407 dislikes ... are they KIDDING ?? must be those armchair do nothing experts ? smh, maybe they just hate their own life ?? sad .. )
Thanks! Had the same problem in my 03 tonight. Thought it was ignition sw.or neutral/park sw. But tomorrow I'll test starter, I tested the relay and fuse already. Same exact symptoms but my battery is new. I'll bet money I'll be changing my starter. 245,000 miles on original. No complaints!
That video was exactly what I needed. Good job on it, I'll subscribe.
I like how you went through the entire diagram and that helps me understand my truck a little bit more.
OMG i learned so much from this video, The Best automotive repair guide I have ever watched and I have watched thousands! Keep up the great work
I've been watching your videos for a while now but I never came across this video which was extremely helpful. I've been having this exact problem with my 03 suburban and now I can finally fix it. You're a lifesaver!!
I really like the troubleshooting in these vids. I spent most of my time in the IT world during troubleshooting. Making assumptions can lead to delays and repeat work. I had 2005 GMC 2500HD with Duramax and the dual factory batteries lasted 9 years. I think the heat wrap they put on them really helps extend the life. I put in new batteries in June 2014 and then traded it in a new RAM 2500HD with Cummins in July. Oh well.
We usually put on new tires and then trade them in
This was well done and helpful, and that's why among all the videos about this issue I am posting the following comment:
If it is the battery as it was with mine, you have to actually INSTALL the new/good battery, NOT just jump it - that will not work. After viewing a dozen videos and forums that's what I finally found out from my shop. I believe them because any other problem with the system would have cost more to fix. Plus it did work.
The explanation from the shop is that it has to do with the computers and complexity of the charging system, and the need for direct cable connections. Jumper cables do not provide the necessary power feed.
Great diagnostic! We need more mechanics like you!
Had that same problem with my 2005 Trailblazer. Did the exact same thing. Tested the relay, fuses, & start wire to solenoid. Same as you everything checked out. Starter was a bit more a bugger to change out, my battery wire at the starter was a little corroded too. So cleaned and put some red battery terminal protector on it. Fired right up!
Great video, Eric! I always learn something new from your videos. I had the same issue with my wife's car a few months back. Lucky for us a tap on the starter with a wrench got it to start and she was able to get it home.
+arcdraw Oh cool, did you get it fixed then?
Sure did! Ran some test on the wiring with my dvom to make sure it was the started and not any wires. Wires checked out okay. Replaced the starter and have had no issue since then!
Most places here mechanics just replace parts if you need them or not.We got burned 2 times from a place here in Florida. Eric you are an honest mechanic
Another good diagnosis from SMA. A job well done. Thanks for the video.
Ive been wrenching for over 40 years. I appreciate the TS you do as Ive been taught both ways. Either at the suspected component first or at the battery and work forward. Eliminates by positive test results.
Nice to see a mechanic who knows his craft. Cleaning terminals, knowing how to test circuits, properly torquing fasteners are just some indicators this guy understands how things work and what it takes to repair it properly. Remember just because we drive away doesn't mean the job was performed correctly. Details are important and unseen by most. Good to see a nice change.
I really enjoy all of your videos. It makes me appreciate a good mechanic who spends the time hunting down the problem instead of throwing parts at it. Excellent job. If I lived near South Main Auto you would get all my business. Keep up the excellent work and keep those videos coming.
Comments like this are the reason why SMA and I make videos for you folks....
Good diagnosis. Myself from experience, I would of went right to the starter, just for the fact that it seems almost everyone I have done like this, where it won't crank in the crank position and the lights go out in the dash, I always go tap on the starter/solenoid first then test for everything else. Any time I have done a switch is when its messed up and has to be broken in order to turn it so it can be released. But at least now I have seen another techs way of doing it and shared experience. Thanks.
My 04 2500 4x4 8.1L, 215k miles Avalanche draining battery when sitting for 2 days. I replaced battery without a test. Still draining battery to 0. O'Reilly tested with handheld, the battery, alternator and starter at the battery. Had me startup and his hh showed starter pulling far too many AMPS. Thus, starter need be replaced. You're testing is very thorough, teaching much. Thank you, for the lessons. I also watched your gauge cluster video. All very informative. I'll watch more of your videos. Its easy to see you can read schematics and know automotive electric.
What a great lesson in diagnostics. Oh, and that relay breakout is awesome.
Starting at the "wrong" end of the circuit did cost you a little extra time, but testing and explaining the different components and functions made this a very informative video. Thanks for sharing.
Thanks for the Help, before I bought a battery I watched the vid and saved me from buying one, it was the starter. Easy except the rotted terminals. Thank you
This was very helpful. I don't know why there are so many dislikes, I guess people just have to be negative. You did a great job on this troubleshooting video.
Very very nice and informative video. I like how you really took the time to diagnose the real problem before just throwing parts at it, too many guys do that waste so much time and money, I had a similar issue on my 2001, however, the positive cable on the starter was loose by about 1/16th of an inch, which aint much, but enough to not allow the truck to start!
Glad you worked through the circuit rather than jump straight to the starter. I'm having a similar problem on a Chevy van, and I'd like to rule out ignition or relay BEFORE crawling under the van in subzero weather and snow to check starter. Your video showed me I can check both pretty easily at fuse box.
As a retired industrial electrician I really enjoy you electrical trouble shooting video's. You have excellent trouble shooting skills. Your starting point logic was sound after getting it to start by playing with the switch. How the heck does anyone get nine years out of a battery? I have a 2006 Malibu I bought new and I am on my third battery.
+DC Rickerson Exactly!!! That is the longest lasting auto battery I've seen
+DC Rickerson Thanks sire I appreciate that. Not sure on the battery though. In our cold climate they do last a while compared to one exposed to a lot of heat and vibration.
DC Rickerson, Buy a better battery. Interstate Mega Trons in my truck and car. 6 plus years now in the car and no issues, just redid the truck. I've gotten 7 plus past experience. I am on the east coast, Phila, Pa. Hot summers and Cold winters.
Try the better Heat beater or Interstate battery, they are the only thing that wors for more then a few years here in the Southwest Tucson Arizona the heat eats batteries faster then a fat man at an all you can eat chicken buffet. Only good thing is we don't get that fine New York rust . :)
love how you test things down to what the problem is....So many do not and are just parts changers. enjoying learning through your videos.
Extremely informative. Clear speaking, explanation and through walk through at a good pace. Thanks!
At my shop we work outside on the rocks. Keeps our creeper from rolling away. For a lift we use a big rock. We do great work at ROCK SOLID AUTO REPAIR.
Great job Mr O. Thanks fer the tutorial.
"Scope on a rope". That cracked me up. Starting at the switch was good for the video because I learned a lot. Thanks for that. I'm starting to see a trend when ever your under a vehicle. Lots of rust on the frames. I guess NY winters are tough on cars.
+wyattoneable Oh yeah the salt here eats them apart. Keeps me in business that is for sure. Kinda same what it does to them though.
@@SouthMainAutoso if the light doesn’t turn on when I’m testing the fuse while I’m cranking it. Most likely it’s an ignition switch problem. So I have to replace it then. My vehicle no start or crank btw
Ben watching a lot of your vids Eric. if you where closer to me, Live in Canada,
you would be the only mechanic servicing my truck. love your chanel.
Great video. Teaches how to diagnose a problem. Keep up the good work.
As a mechanic who gets paid to fix things, I can see the advantage of replacing the starter as a single unit. For the home mechanic, does it make sense to replace just the solenoid? I suspect the new starters come from China and I don't like Chinese parts. Often the new aftermarket parts have a much shorter life than the remanufactured parts from a few years ago (before China). I know when the voltage gauge on the dash was all over the place many years ago, I took the alternator apart and replaced a few parts (regulator) and it still works perfectly fine.
On my 2001 Silverado my original starter went out with no warning at all. Drove it to a job site just fine. When I came out to leave, nothing. Did the starter right there in the parking lot. Be VERY careful of the crank sensor and harness. I damaged mine because I hadn’t done that on this truck before. After doing the starter the truck cranked but wouldn’t start! Had to take the starter back off and rig the CPS harness to work just until I could get home and do the starter for the 3rd time! I will say 18 years of near daily use is pretty impressive for a starter.
Nice video. Who the heck would check the starter first after wiggling the ignition key and getting a no crank no start to start. You went about your diagnosis in a logical manner.
+Michael Herbert Yeah looking back I would have done it that way again I guess
I want to thank you for all the great videos that you have put online for people that are working on their vehicles and don’t understand as well as you know as being an expert you’ve helped me many times when I’m searching for answers I want to tell you thank you
You are such a good mechanic. Much respect man!
..a nice detailed approach. We actually started with the starter, replaced, worked to get home.
Sadly, it's still there,..back to no crank, no start.
What was your solution? Did the same and no luck. gonna check the fuses this weekend
@@McLetra17
..ended up being a 'bad' refurbished starter,..ended up having to get another and this time, it was installed by a service tech.
Great video by a intelligent mechanic! Thanks - thumbs up!
You did it the right way Eric. The ignition switch would be cheaper than the starter so in the unwritten law of mechanics 101 of throwing the kitchen sink at it till you find the problem,you would always start out with the least expencive parts,then work your way up to the big $$ items. As follows. Car wont start. Check fuses. Check relay,wiggle wires,check for corrosion of all wires ( naturally) then take a hammer and wack the starter .If it starts then you drive it to the auto parts place to see if they have a starter. Then you shut car off ( by accident) find out they dont have it at that store but the one across town has it. Go out to start car,no start. Hammer method no longer works. Call everyone you know,no answer.End up laying on parking lot in the rain to change starter,short out fuse by forgetting to disconnect battery. Finish in the dark only to find out battery is now dead,get jump start. Wave goodbye to all your helper friends that finally showed after you finished. Jump in car pull headlight switch only to find out the headlights and dashlights no longer work,its dark,the store is closed and no one is around. Oh and did I mention your cell phone battery died just as you started dialing a friend. Yup,one of THOSE kinda days.
Good job on the Disclaimer Eric Very good job. Now you're covered my friend! . Jim told me to tell you that!
Alot of mechanics will just start throwing parts at the problem. Good job being a troubleshooter/problem solver.
Thank You Eric you are awesome for allowing us to see your professional work well explain.
This is how a great mechanic diagnoses an issue! Great video! Thanks!
Very good job. Very informative and very thorough.
Eric, I like the way you are working the electrical schematic into trouble shooting this no start condition.
I feel you on that ,I have a ex new York police tahoe at the shop with a hot soak no crank that I cannot duplicate, probably needs a starter but until I confirm its a no go
+Michael Berg Can't you throw a scope on it while it is working to see what the waveform looks like and maybe make a decision based on that?
Tried both a scope and a midtronics tester with an amp clamp nothing off cranking volts were normal, 2 days with it, it never missed a beat even letting it run for an hour several times, he picked it up Friday no charge no parts replaced
Bummer man...
+South Main Auto Repair can't win them all
Had a lot of no starts on chevy trucks the two positive cables loose or corroded at battery
I'm working on my son-in-laws 01 S10 4.3L Automatic. The truck was over heating. I had to replace the intake manifold gaskets. Of course you know what all that involves. After replacing the gaskets and put everything back together, the truck will not turn over, it was running before. All we hear is a click under the dash when the key is turned. I've checked the battery, its 12.4 volts. I pulled the starter and had it checked. It was good. Although the connector on the PPL wire broke, I replaced it. I used an OHM meter and checked the grounds and they checked out good. So did all the fuses. The only other things i have not checked is the P/N safety switch and the IGN switch. Good video, Iv'e got to check out your other videos, so I can figure this out
I keep telling my guys to watch your channel
+Scott Stephens Sure , come on over!
It is the most informative and easy to listen to site I have seen.Scotty Kilmer is a bit wacky and rough but you have got a lot of great tools to use.
Thanks Eric, I have a 02 Tahoe that had the same symptoms no crank no start, switch out new starter, fired right up .Great videos .
Great job and video! Ive been watching Eric O's videos for a few weeks now (found him thru an ETGC video) and really like the fact that that he is not only good, he is HONEST. That is the biggest 'lost skill' of today.
In this specific case Im wondering if it was possible that the no crank was due to the weak battery. We never saw a test of the old starter with a new battery (or bench test of the old starter with bench power supply) and Id be curious to know that result.
Thanks
Very good example of how to diagnose a issue instead of changing bits until you fix it, great job bud
+James'sWorld You gotta test first!
I always tap the starter with a hammer to see if it starts working. It can save on towing.
+jeffscomp can't always do that tho, some starters have magnets you can damage that way.
+jeffscomp Yeah, you want to avoid the hammer bit. Starters have magnets in them, and if it isn't the starter itself, you'll crack them up and destroy the starter. Best to tap it with a piece of wood or a small deadblow hammer or something, not too hard.
you can hit a starter pretty hard before you break it, trust me, a dead blow or a piece of wood sometimes doesnt work, for example on my truck the starter locked up at work, went under there with my baby hammer and tappity tapped and nothing, it finally cranked over when i gave her the shit. didnt crack my case or anything. if you have any decent knowledge of vehicles you should test everything before you condemn the starter with a hammer. i always carry a test light with me. the joys of being a paranoid mechanic lol
That's why I have AAA. :)
16B9: AAA has saved my beacon many times.
Your AWESOME previous video helped me out with the 'Oil Pressure Sensor' and saved me over $600 now i just need to fix my no start issue, this video may not be the answer i was looking for.
Passlock system above key loses connection--bang on steering wheel and it starts. Well on my 2004 GMC Sierra it works.
When I went to work for Sears Automotive they sent me to school down in Atlanta, GA for starter, alternator/generator, and battery school. That was my first ASE Certification test....Next was alignment training. All this happened almost fifty years ago.
Did the door " ,DINGDINGDING", START WORKING?
You are still the best mechanic on You Tube!
Wish the body on my 03 ZR2 looked that nice. Good video Eric!
Thank thank thank you! Your first sentence was the fix. Bad switch. A little extra torque on the start and bang. Starts right up.
Thanks for the showing the circuit work.
GM should have done a recall on these security no start issues
Another culprit is the Discrete Logic Ignition Switch (DLIS) Fuse under the hood. Great video that walked me through all needed checks for the exact same symptoms, but ultimately ended up being a corroded DLIS fuse (2A).
Impressive thanks for taking us through this
I just bought a 2003 GMC HD and have this eractic starting problem like ur talking about. You had stated that the battery was really bad in it the dash lights etc would fade out. I know low voltage takes out ECM, and other components and probably burnt up this starter. I was surprised that you didn't show us that it cured the problem before you put the new battery in. I'm thinking the dead battery probably had a dead cell in it. Your video really put me on track to go after my problem. I deal with helping truckers with ECM problems and troubleshooting. Keep up the good videos. I starting doing videos on L10, M11 & N14 Cummins engines 10 + years ago and get calls for everyday of the week. It's good to see other people sharing their knowledge with the rest of the world and seems to be growing more and more. Wish you were near by, I would definitely take my truck to you! Thanks Terry Chron. I let you know how this one turns out. The guy said it has a new battery and starter less than a year old. I was thinking the same as you, it has to be the ignition switch and or the relay which I had no idea was on this truck. I'm 68 years old and I hate working underneath trucks anymore. I hope it's the relay or ignition switch. Bur, youir video makes feel like buying a new battery and starter and taking a chance haha
So good..... I watched it twice👍
+Typey1 Not good enough for three huh lol
Thanks you for going through process of elimination. I am facing the same issue with my 06 tahoe variant. I have replaced starter and ignition switch with no positive impact. I shall run the steps with light probe.
Had one of these kick my butt last month. Made me feel good to see you struggle a little bit. Not the best design...
+Roger Anthony Yeah all the lines and wires there made it a little difficult to remove but not to bad.
excellent diagnosis and problem solving. great job at finding the real trouble here.
Nice job, as always.
Your video is the best that I've seen. Too bad I didn't see it until today because last night I attempted changing out the starter. It's already been diagnosed as the starter. I wasn't able to get it out away from the bell housing. Your video is the only one I've seen working through the wheel well to get the dust cover and cables off the starter. I can probably remove the wheel to give me more space since I don't have a lift.
Awesome bro, you saved me.
Damn good video and a great diagnosis procedure. I’m an aircraft mechanic and I don’t give compliments out easily ! Well done sir ! You taught me a trick as well ! Awesome job !
Could you do a video on what you use to pull up wiring diagrams?
Google. They're everywhere
Experienced the same identical issue, as have many others from reading postings on different web pages and blogs. There must be an OEM issue with starters or the solenoids going bad. Troubleshot mine via the same approach and it was the starter too. Nice post. Good methodical approach. Thanks.
