- เผยแพร่เมื่อ 25 ส.ค. 2024
- In today's video we have a 2007 Chevrolet Colorado with a 3.7 liter engine. The vehicle is a no crank / no start and no communication. The previous mechanic tried replacing the fuel pump, starter motor and ignition switch, but still could not fix the problem. Follow along as I take you step by step through my diagnostic procedure and fix this truck.

I stopped here because I own one of these vehicles. Watching you work was a lesson by itself. Very methodical and thorough. Good job!
You are the Sherlock Holmes of electrical issues....very professional !!!!!!!!!!!!!!!!! :)
Thank you
Eric's more like Sherlock OHMS lol.
tecnaman yus, he finds the resistance and sorts it out appropriately..
This shit is informational. You best recognize!
Much respect for being humble and not editing out your little test light mistake. You're an diagnostic machine! Great video!
That’s how you DiagNOSE a vehicle 🥴😷
Haha!
Hey Homie luv your videos bro!
🙏🏻👍
I can see your smile 😀 at 26:10 👍🏼 Beautiful work Eric 👊🏼👊🏼
Thanks bro!
@@ADVANCEDLEVELAUTO also, please kindly make video on how to check the blowby gas with details illustration in new cars and old cars respectively...
Excellent diag. You went the extra mile. I would have shipped it with that stank to a detailer immediately after fix.
This was probably the best, most easily understandable automotive video I've ever seen on youtube!!! The full video showing mistakes and every detail was awesome! I thank you for this amazing video!
Que bien trabajas, sigues los pasos que debes seguir hasta llegar al problema.
Felt like a kid from those interactive shows trying to tell you your light is on the positive terminal 😂😂..love the content stay safe and continue doing what you do ..mutch love from Cali
Salute.. nothing else to say what a Comeback after a major Setback... wish you the best!!!! So inspirational watching you, as a young automotive student starting in trade. Don’t stop the videos, just know that you have students watching you and learning from your craft. Thanks!!! 😊
you probably dont give a damn but does anybody know of a trick to log back into an Instagram account..?
I stupidly lost my password. I appreciate any tricks you can give me
@Frederick Nixon Instablaster :)
@Joseph Maverick Thanks for your reply. I got to the site thru google and im waiting for the hacking stuff now.
Seems to take quite some time so I will get back to you later with my results.
@Joseph Maverick it did the trick and I now got access to my account again. I am so happy:D
Thanks so much, you saved my ass :D
@Frederick Nixon happy to help =)
He needs to go back to the other shop and get his money back, they were just guessing and replacing parts at the customers expense.
The old parts cannon indeed.
That's why I always do my own repairs. Any idiot can throw money at a problem.
This one was really interesting, really it's very difficult to fix a vehicle that had been sitting under sun on such hot day😉
Stay Safe
Being from New England, it must be actually be fun to work on a thirteen year old truck that isn't a pile of rust. I couldn't believe how clean the underside was. But I guess rodents are a universal problem. Somehow they always end up dying in the blower motor wheel.
to them it's the treadmill of death lol
"Engine cranked." Oh that priceless feeling.👍
like the way you follow your procedure. it's hot here in georgia, i know it's hotter in houston
Love it when a plan comes together! Nice job!
What a great video, this is the exact issue I had on my Colorado. You save me a ton of time, money, and trouble. Kudos, sir!
what was the problem and how did you fixed it Sir? btw I have 2016 colorado 2.5 with same issue wont crank, I wonder if the truck are all lemons
@@humlocker it turned out that the wire that connects the ignition lock to the starter had corroded away. I had been using a paper clip in place of the relay to jump my truck, so my mechanic just installed a 7$ push button switch on my dash. Hope this helps.
@@humlocker a
I became a mechanic just by watching your videos...😀
That is actually cool for us here in Phoenix Arizona come and spend a few days over here so that you'll see what the real heat is
Dude you explain this better than anyone else i struggled for so long to learn this i am getting it i cant thank you enough you could be a great automotive instructor keep these videos coming you also have a great personality
i would appreciate you being so humbble as an automative engineer explaining evry single step so that everyone could understand deeply what's going on there.
warm greting from iran
That’s awesome! You have to acknowledge someone that can diagnose and find the problem. Not just throw parts at a car. Two dumbs up for you 👍🏽👍🏽!
The huge difference between a really good mechanic and a really bad one in one single video. Excellent video and very very easy to follow what you're saying.
I just dealt with this exact issue on a 08 malibu. Same scenario, ended up taking the fuse box apart and load testing the copper wires. Turned out bad pcm. Was so stumped what happened glad to see somebody else ran onto this. Thanks for content!
Erik you're the freaking man. Love your videos! Wish there was a new video every day!
Ditto about clear explanations! Your vidios are just what the novice DIY electrical needs. I even caught the test light mistake before you did! Great learning experiences! THANKS.
All these TH-cam videos and people still just throw parts vehicles without doing a little diagnosing lol. Good job Eric 👍👍👍👍👍
was searching no crank no start issues cam across this video. Had to pause 3 times and buy tools, don't need em but they all looked handy! great tips and links. I work on a lot of stuff and have to say never 1 handed and never talking to a camera... Man you are in the right business, but you should be running a vo-tech! You are right there with South main auto Repair! Great video!
Excellent video. You are a good teacher. I need to learn how to read a wiring diagram, it’s all Greek to me.
Thank you for keeping it unedited. Great to see you drop the relay in the engine bay like we all do. Thanks for making this video. Funny how hot it is & as of this writing, it's the coldest in Houston in 100 years.
You are a true problem solver my friend. Outstanding and appreciate your candor and honesty.
Weird they replaced the fuel pump for a no crank.
I think it was a crank no start at times, but when I checked it wouldn’t crank at all.
Did they checked for fuel pressure first before making a desicion?
@@mtsanchez27 look they watched the scotty kilmer video, ok?
@JEJU S CLASS 600 are you serious?
No, way. What that got to do if it didn't even crank
Thank you! I love your "won't edit this." You appear humble, methodical, yet brilliant! :)
My Colorado has all the same symptoms as this one. Thank you for posting this video, as I now have something to reference to figure out the problem.
Did you fix it?
I’m having the same problem haven’t checked for that wiring spot
@@efrenestrada1482 Didn’t fix it, I think mine has a bad ECM.
All diagnosticians know that familiar laugh of achievement 🤜 .Keep on keeping on
i live in Miami and i'm old best money i have spent has a 100 dollar pop up canopy takes a couple of minutes to assemble
juan rodriguez, pop up tent a really great idea!
@@unclemarksdiyauto you can use old brake rotors on the legs to keep it down in the wind
@@juanrodriguez-ry6yt you are spit on with that. I’m in Naples and I’ve been doing that for years
Thorough, meticulous, patient diagnostician, very well done!!
Great eye Eric!
That feeling when you getting it running. Awesome feelings. Good diagnostic.
That 3.7 5 cylinder engine was great. GM should bring back this truck.
Just repaired my Colorado with the same problem, but behind the ABS valve, Also in the past squirrels have eaten my fuel lines three times. Thanks, you saved me a lot of money. I sent you a small thank you thru paypal.
Thank you very much. I’m glad I could help!
excellent job of troubleshooting. reference wiring diagram and use voltmeter to find fault.
This was the funniest diagnostic I’ve ever seen. “What did that rodent have against me” lol, I feel your pain brother….
Most electrical problems are in the wiring or connectors. As you demonstrate, there is no tool better than the eyes and using them for a thorough visual inspection. Working in that sort of heat and concentrating on the task at hand isn’t easy. Well done!
Great Video. So sorry to see that you lost your shop space but am glad you are still wrenching. I am a mobile mechanic here in central Virginia and the heat and humidity is nasty. I spent two months in a shop and one day a similar problem in Mercedes. There was dog food in the housing of ECM. I was told not to pull out the computer to clean out the dog food but just vacuum it out. I KNOW there was a wiring issue under the ECM but wasn't allowed to trace it due to "it would cause more problems". I left shortly there after.
Another advanced diagnostic video, Eric 👍 👍. I notice Houston's heat this year is a bit hotter than usual. Stay safe.
Very hot!
Thank you Eric. Good job. Have a blessed and safe week to you and your family.
Just another day in the life of a Automotive Technician! The last guy to work on it was just a Mechanic,and that's ok.. but Dont charge a customer for your Education, or the lack of. And Most don't take the time to Really Diagnose problems. Or don't Possess the skill sets to brake it down to really diagnose something! Always looking for a quick answer.
Nicely Done ! Good Job!
Please show video on how thermistors in power window motor behaves to protect them from over loading current...
You're the only one on the channel who returns and answers comments and knows electronics you're the only one who respond to a comment other than a love heart keep up the good videos love your channel
Thank you
@@ADVANCEDLEVELAUTO have you ever seen Scotty kilmer respond to a comment other than doing his live chat of course not and I'm not the type to talk about dealerships and car manufacturing how bad they are especially when you put your house on a social media and everybody knows where you live that's not the smartest idea maybe that's why he had to move
@@Joeelectronicschematicsforauto He probably gets so many comments that it's hard to keep up. I do question how he is actually helping anyone by bashing every manufacture and telling you that your car is a piece of crap and you shouldn't have bought it.
@@ADVANCEDLEVELAUTO I agree with you 100%. How can you talk bad about every manufacturer and car dealership and stores don't buy from this store I would be afraid to show my house where I live I mean we have to remember it's not our job to rate the quality of cars just to fix them that's all
@@ADVANCEDLEVELAUTO and he's bashing the cars manufacturers like you just said he's he's been making a pretty good living repairing those cars that weren't good in the first place like he says so you really can't complain
I was a mobile mechanic for year's. I always used a 12' x 12' Colman easy up.
Man... My 05 just did this exact same thing the other day. The low fuel light and everything! I was really hoping you found something other than cut wires. At least I know where to start now. Thanks
Great Job
I have numerous problems with my 08 air conditioner works when it wants to heat gauge won't work unless air comes on blower works intermittently what headach now it's not wanting to crank now and then.
Wish I had your talent
that is how its done! good technique eliminating possible causes, dont stop your ways
That’s some master tech diagnosing 👍
Thank you, I would like to give you five stars on your fine work and explanations.
Great video man, I have learn alot from you and I thank you for that
Also I didn't watch all of the videos im changing my Colorados Transmission so I was just getting pumped up and helping out along the way lol but have a good day.
Your the best...watch lot of vids and find your the most straight forward and complete...keep them commin
I shared that victory with you at “Waalaaaaa!!!” 😂😂 Great video and you simplified that waaayyy too much! Lol Good job Eric!
your vids are so real world. valuable
No better feeling than when she fires up.
Good work.
Great diag and visual👍
You're talking about being hot wait till Feb 2021 when we all froze in Texas! 🤣🤣 Another good one bro, keep em coming! Peace
I have the same problem here in Ohio. I was told that GM used some sort of coating on their wires that mice love to eat. My brother has a new GM vehicle the mice already chewed up some of his wires. This is a great video, thanks I am going to try and fix my Colorado now.
Momento de magia! Felicidadees 26:03 !
Thanks, I am having an intermittent issue of this effect where there’s no crank no start but it’s totally intermittent and runs more than it doesn’t. I will definitely start looking for the check engine light. Goes to show you with electrical it could be anything. Most mechanics around me were advising the starter, but this goes to show that I shouldn’t jump right to the starter.
I like you so much bro. I have learned alot from you.. I wish I was your student.. Warmest greetings from Abbas.... Kurdistan region of Iraq. Infinite 👍 to you bro.
your a smart mechanic I wish you where in my area
Good find. Stay safe.
Excellent job. I love your unassuming approach to troubleshooting. Most people would have went in a different direction. Like thinking a defective clutch switch. Because of you, tomorrow I'm going to check the ETC FUSE, POWER TRAN RELAY, AND all visable wires.
I just love when I hear that the vehicle came from another shop....
I was listening to the video while I was driving & I spent a good 20 seconds looking for the ambulance!!🤣😂😁
Nice fix except next time, "listen" to your nose and put gloves on, rodent droppings can be extremely hazardous to your health. You can disinfect your hands with brake cleaner or carb cleaner on hand if nothing else available. Don't forget to wipe any tools that may have gotten touched/contaminated. Can't be too careful especially when you've got kids and/or wife back home.😷🐁🚑
Brake clean and similar solvent are NOT disinfectants, do not think they will sanitize your hands! The alkanes contained in them will have no activity whatsoever against any biological contaminants. 70% ethanol or isoprop will though!
@@jovangrbic97 Firstly, I said IF nothing else available. Secondly, if you don't believe brake cleaner or solvents don't kill biological organisms, try drinking the stuff . There's ample warnings on those products regarding adverse health so don't be a wise guy or girl if you identify as one. Cheers!
Great diagnosis and fix. I wonder if it died biting through that second wire, there was a curious stain right where the harness was at.
Did any one else see the bad green wire 🤔 he missed. But good job on finding the bad wires 👏 👏 👏..
Wow !!! you really show passion and love for what you do, Thank you so much for making this video, I and I am sure many people appreciate the effort you put to make this video for teaching us how to troubleshoot this electrical issue. God bless you and your family.
Nice one bro🤪....Always amazed how our little rodent friends can chew on just the right wires to cause so much fun....Broken Orange wire was the Bat+ from fuse 30 to PCM, and the semi-intact WH/BK wire was the PCM relay control wire, hence why we saw no control at the relay👍🇦🇺
Ur absolutely correct had to look over wiring diagram CHEERS wh/bk pcm ground
@@anthonysova7117 Umm no, the WH/BK is the control wire that the PCM grounds to control the relay, not a PCM ground!! It's pretty straight forward, just refer to the wiring diagram Eric showed in the video.
I said it once before you are the man very nice job I’ll give you a 10+ on that go get something to drink and cool off.
HELLO ! Fantastic car repair SUPER MEN !!
I appreciate your teaching style. That's how to learn!
Thanks good video keep like that god bless you and you family
Nice work Eric! I wonder why they changed the fuel pump for a no crank situation? SMH
Brandon C because they a bunch of amateurs bro! Just chuck a bunch of parts at the car until something works..
Expert point A to B troubleshooting, keep up the good work. I viewed your going out of business video and things will work out for you because you have a lot talent that comes from attention to detail and research and will take you to the top. I know what it's like to hit the schematics and research right to the cause. Thanks for your videos and your talent will take you to the top.
Awesome as usual dude, "YOU DA MAN"
Great job.
It's not the problem I have on my Colorado (no start, except that's intermittent) but I think I have an electrical problem - somewhere. It's too dang cold where I live right now and I no longer work as a mechanic so I'll wait till it's a bit warmer. Wish I had the diagnostic machine like you have there. Shop quoted me $1100 for a fuel pump replacement and maybe it needs one but I'd rather do it myself for that kind of money. And I no longer "get into" working on my own stuff.
Need to do a video on why the windows don't roll up or down, except right after the truck starts :)
That was absolutely brilliant, You are a true professional
*@**2:20*
Not only is the CEL Telltale out, but the PRND321 is also blank.
On an older vehicle- the Neutral Safety Switch could be tested,
by holding key in RUN and jiggling shifter from P to R. If it cranked
the NSS was loose, "out of adjustment" or faulty.
Excellent to outstanding you are a true professional bro
Hitting you up from the Bahamas. I had the same problem with my 2008 Colorado. Unfortunately I had already bought the electrical part for the key switch (couldn't return it). Rodents bit up four of the wires leading to the computer. Good stuff my brother, good stuff!!
All your videos are full of priceless information. Thanks for sharing your experiences. 😊
Systematic Troubleshooting!
Xcellent Work!!!!!!!!!!
you are the man, nice fix Mate
Love your videos brother!..explain everything very well and you go through the entire diagnostic process..I was just as excited as you were when she cranked..
This was unbelievably informative. Thank you for uploading this and sharing your knowledge and expertise. Much appreciated.
Will it start? Our favorite question, LOL. Great video and the proper way to diagnose a vehicle.
Hey Eric ,great video! I really appreciate... I am sure all of here appreciate your extra work to make these videos! Thanks and God bless you!!!!
Liked
Thanks for the video!
Life is a learning curve!
HINDSIGHT is 20-15!
Thanks for leaving your mistakes in the video! We're all human!
Even though I live in Leeds England and work on european cars your videos are great and very good for people to learn from as the electrical side of cars are very similar on all vehicles keep up the great videos and I hope all the best for u and your famliy
Thanks for the upload 👍👍👍👍👍
