eric great job as always i love how you explain everything in detail i have a 2004 chevy silverado with the 5.3v8 and it every now and then does a security lockout on me for like 15 mins where the vehicle will crank over but there is now fuel or spark being supplied i assume and there is a lock on the indicator lights in the dash that lights up any idea what to do in this situation it really sucks

good mechanic ! I like mechanics that make sure what the trouble is before doing a bunch of work that's not needed !

A pointer to those who Checked over the same trouble shooting that this guy did and do have power key on and starting position, could be the control module next to the coil. Just fixed a 2005 4.3 vortec. Thanks to this video for singling out other potential problems! Thumbs up!!

Love going way back and watching these early episodes!

@sky3353 8 лет назад

Thanks for the videos Eric. Very good explanations and easy to understand. Watch them for hours. Just an old guy that likes to learn and tries to do my own work. Thanks.

@scottlaster1763 6 лет назад

I realize this is an older one, I am amazed every day by how many people would replace half a dozen other components before checking basics like power to the coil. Great post, straight forward diagnostics. I am working my way through them Eric. lol

@danfogg4848 2 года назад

That's great. It's good to see actual mechanics still working correctly. There's to many part's replacers out there.

@bfordcole 3 года назад

This ended up being my problem 2000 Safari Van. This saved me so much.. I have to order the switch and install it.. I made a "Hotwire switch" to get the van to move. I am glad that people are doing these videos. Thank You!

@johnkirkland3888 9 лет назад

Absolutely awesome. My favorite videos are the ones where you have to get into the wiring diagrams. Probably because that is one of my weak areas. I'm learning though. Thanks for this video.

@ericg4915 3 года назад

Its everybody's weak area, the most complicated part of a car is the electrical

@andyginterblues2961 Год назад

I only wish that I watched this video a few months ago, now I know exactly what I need to check for to get my 2003 Chevy S10 Blazer running. It would have saved me from a lot of agony, ordering new parts that I probably didn't need etc. It's been cranking but no start, Thanks for posting!

@RC-Heli835 4 года назад

Of all videos I would have expected zero thumbs downs on this one. Awesome work man. Once again you tracked it down like a hound. The wiring diagrams are an invaluable tool. It's a shame they are so expensive.

@chrismojica8357 Год назад

Just replaced my motor on my 99 silverdao having the same issue no spark thanks man you really gotta keep making videos for people like me

@BUTGOD-j1x 3 года назад

Beauuuutiful video! Thank you South Main Auto Repair for taking the time to show the most thoroughly done diagnosis I've seen on a No crank. Step by step. Awesome! And I like your sarcastic humor too. Thanks RU-vid for creating a platform for skilled mechanics to display their skills for all to see. Blessed!

@B81Mack Год назад

I was hoping this is my problem but it isn't. Nonetheless, I like the articulate and thoughtful analysis presented here. This man would make a great teacher/instructor. Well done sir.

@elidames6889 6 лет назад

This explains why my 01 blazer won’t fire up but sounds like it wants to when I stop cranking it.

Excellent, clear breakdown of all the wiring and diagnostics. Thank you.

You win the prize for the best diagnostic video ever on you tube I've ever seen. You're the man Eric!

@RyouConcord 7 лет назад

Thanks for the video. On my 97 S10, we didn't end up needing to replace the ignition switch, but watching this helped us rule out the ignition switch: turns out, it needed new spark plugs.

@chrisbeavers123 Год назад

I want to tell you this is the best most thorough video I've seen online. Excellent source of information.

@nunya6834 7 лет назад

Great video. Thanks for showing the correct way to diagnose a no start vehicle. Precise and to the point. My sisters is doing this and mine 98 Blazer won't start when it's cold outside. I'll have to try what you did in this video. Thanks again for a great diagnoses on a vehicle.

Saturday May 23, 2020.. after replacing fuel pump, relays, fuses, fusebox, coil packs and even ECM. Found your video and IT WORKED THANK YOU VERY MUCH. Ran out $ by buying all unnecessary parts.. so I'm running with a hot wire hanging out lol. I APPRECIATE the wiring diagram. Colors helped out a lot since I was trying to guess

@buddasro1 6 лет назад

Wow! So glad i subbed your channel. I watched your vid on belt tensioner r&r tuesday and ordered the part. While i was at advance my friend called me and said he was experiencing this exact issue and we were stumped and called it a night. Open up RU-vid tonight and this video was first in my feed! You rock, thanks for posting great USEFUL content!

@RDG.357 5 лет назад

Pretty sure you just fixed the same issue on my '01 Jimmy... Thanks for the vid!! I was getting ready to buy new plugs, wires, cap & rotor hoping it would solve my issue (it still needs them, but it probably wouldn't have solved it & I would have driven it off a cliff because I am tired of sinking money into it.) :) I work at a different auto parts store... Same issues with the bad box & used parts sometimes making it out. We are supposed to check returns at the time of return. You don't take the cutomer's word for it that it has not been installed / used. Also ~ the warehouse is supposed to check returns that we send them, especially if they are being returned as "new"... We get boxes that look like that one from our warehouse!! I always check the part if I come across one. Basically it is told that "well, you don't install the box!" ugh. No, but it is pretty crappy to hand a beat up box to a customer... doesn't help their confidence in the quality, even if the part inside is fine. Usually it is one of the last ones on the shelf in the warehouse though, so getting another one may take longer, if it is even still available. We can only do so much. Which is why I check the part & usually ask the customer to look it over in front of me, just to be sure it passes their inspection too. Apologize for the crap packaging & move on.

@quickdeuce 5 лет назад

Thanks much, it was cool watching a pro work through the problem instead of just throwing parts at it - as "some so called" pros have done to many of us, THEN they charge us shop rate PLUS all the unnecessary parts for their education. Yes, some of us have had it happen. It's so cool to watch you eliminate the many various parts as the possible culprit and zero in on what the main problem was.

@lothoglas9793 8 лет назад

Had a hydro-lock issue after replacing fuel injector spider assembly on a sonoma v6, cleared that and had a crank/no start issue. After some testing decided my secondary coil on ignition coil was bad. Hoping to see some tips...but ended up thoroughly enjoying how you traced out the problem so much I forgot I was looking for ignition coil replacement. Great job!

@scooterdog29 6 лет назад

Really like your vids. You are clear and loud, and you know your stuff. Working on the damn crank sensor now. thanks for the vid

@kenknight6629 8 лет назад

This is the best diagnostic video I have ever seen. I loved the way you used the test light to diagnose this. Great job!

@jamesrice9975 5 лет назад

Cuz hes the real deal right. I think I cn learn something here. I am shade tree myself (back in the 70's) and now trying to pay off my lift. I just poured concrete and installed a lift so I can enjoy my hobby. who knows, I might even make a buck. Now that I have my shop set up, I need to learn how to make youtube videos. So anyone that wants to give a tip, I a more than welcome that. thanks

@jamesrice9975 5 лет назад

Computers on vehicles now is my biggest hurdle. But like I said, I installed lift and also bought a OBDII scanner so at least I am trying. It is the same basics, just learning to talk to the computer, or is the computer talking to me?

@63256325N 6 лет назад

The first thought through my brain was ignition switch and mice. I was wrong about the mice. Thanks for the video.

@michaelward668 3 года назад

I wanna say thank you for the information you doing a great job yet helped me out on my sons 2000 GMC Jimmy engine wouldn't shut off and tested Ignition switch it was bad. So thank you keep up the good work sir

@Inisfad 4 месяца назад

While I know so many of us now have new, computerized cars that give us all the information that we need to diagnose, there are still many of us with old clunkers, as well as the need to be able to deal with these issues through ‘old school’ efforts. I’d like to see more of these.

@joemikos9155 9 лет назад

Awsome job! I was mechanic for 20+ years, ASE cert in all aspects. I owned a shop with 20 +- employees. Did mostly HD trucks. I'm sorry, I digress. After years (17) of being out of the buis I realize I need much retraining, (had cancer) Your vid is inspirational and has reminded me I need to stay patient, (weak area for me). As I gain strength I have been getting back into it. As you know it gets in your blood. Thanks for the inspiration. Much respect!

@SouthMainAuto 9 лет назад

Joe Mikos Do you mind if I ask what cancer you had. I just watched my dad, a heavy duty shop owner of 34year go through it.

@SouthMainAuto 9 лет назад

Your welcome! I hope it solves your problem. Pretty easy condition to test for if you have the same symptom. Did you see the link to the R&R procedure for the switch?

@oldmanaero9962 7 лет назад

Hello Eric, Thank you so much for this video. I had the same exact problem with a 2002 Chevy Silverado I bought used a few months ago except mine was an intermittent problem as that last little bit of spark at the end of the crank cycle was enough to start the truck....but only when it was warm, as it got colder I would have to crank it for numerous short bursts until it could fire with that tiny amount of spark on its last 1/4 turn. It took awhile of checking things until I realized the motor would only start as I disengaged the starter. From there I was lucky enough to find your site and search my problem. I couldn't find a wiring diagram for my Silverado but took a chance on the ECM1 circuit and it was the same as the Gimmy. For anyone else out there with a similar problem don't let the hot start cold no-start thing throw you because it still could be the ignition switch. Eric you have a great selection of help videos and do a great job of teaching. Cheers to you! Dean

Thank you so much! I'm 95% sure this is exactly what's going on with my 1998 Chevy S10. I've been noticing the last month or so the engine starting when I let off the key most of the time. So when I saw your video and the same thing I was for sure that was the problem. So I had my wife come Al and start my truck while I tested the fuse but... The truck turned over no problem.REALLY!?! I did remove that fuse and reinserted before I had my wife crank it over so I'm not sure if that helped the issue. Guess I'm going to wait to see if it stops working again. But thanks so much for your work

The way you can communicate your expertise to us DIY'ers and professionals is unlike many other "gearheads" that I've come across on the net. Like probably all of your other followers, I too, am having car problems. But I'll leave that for another day. Right now I'm just gonna amaze myself with your talents and enjoy your videos. Please keep up the good work!

@athulbnair 8 лет назад

Great to see how you diagnose starting trouble. In India they will not do this, will ask us to replace parts without any genuine evidence.Once my old 2007 model Suzuki broken down, on the next day, after regular service. On-road assistance guy came and told the car need multiple part replacements, including alternator. Finally he figured out it is a loose contact in a particular switch. That guy did that fixing by trial and error and I have not replaced anything in contrast to his initial conclusion on part replacements. While I questioned him earlier how he had concluded car needs part replacement he is unable to answer me.
