- This video is about my CoPart Hummer Purchase and the issues that I am discovering along the way. This Hummer was bought to be a Father-Daughter project for when she turns 16. We will learn and fix it up together, I just have to get it running first. But, a potential Rod Bearing problem and a Stalling issue is keeping us from diving in and really fixing it up for her. On this episode, we try to diagnose the Stalling issue by installing 2 Camshaft/Crankshaft sensors.

My 2006 3.5L was doing the exact same (extremely rough idle, stalling, no power on acceleration, dying out, was exhibiting a little knocking but more like when it's running too lean) thing after replacing the coil packs. What mine ended up being was a dirty and loose MAF sensor. So I cleaned it, made sure all connectors were snug and thoroughly cleaned the throttle body. Haven't had an issues since. Just sayin, in case someone else with a similar problem stumbles across these comments.
Awesome, thanks for commenting. Mine ended up being 4 out of 5 crankshaft bearings were bad, but, the same changes I made with the sensors and so on have fixed other Hummers according to the comments. Thanks for watching.
The h3 is 👏 love mine. Easy to work on. Quite reliable if you go easy on it. Does most everything you need it too do. Mine has 415,000 I’m now and still going strong 💪 I’m decently mechanical so I go over it twice a year and replace whatever it needs 4:28 myself. Blew the cat last year and dropped in a new manifold. Blew the water pump the year before. Changed it myself. Alot of the parts now are pretty new. I try not to question too much if I need it I just get it. Can’t go wrong because it will always be far less than buying a new vehicle 🫡🇨🇦
Wow, that’s some impressive mileage. Love the H3’s. Sold it and got an H2 as that is what my daughter really wanted. Love it also. Easy to work on. Thanks for watching and commenting.
It's a good thing that this project happened five years ago because you would have one hell of a time finding some replacement parts.
I currently own a 2009 Hummer H3 with 3.7 liter 5 cylinder engine with 121, 700 plus miles that I put on it. It was never abused or driven hard. Mostly Highway miles. The only problem I have with my Hummer is the ECM -- engine control module might be going bad. It was displaying several dashboard codes. I had the ECM reprogrammed by a good programmer and he cleared all codes for 1 day. Then I parked it for a day and the same dashboard codes displayed when I started the engine the next day, I let the engine warm up for a few minutes and the dashboard lights went off and the check engine light came on steady. So I connected my diagnostic tool under the dash and it was showing the O-2 sensor was bad and the EVAP valve was bad.
If your still dealing with this ...clean the throttle body flap..they build up deposit really bad and mess with the position sensor on it..also clean or replace the maf. Good luck as for radio..when you take it out there is a little box that allows you to adjust the door chime and excessories beep
@Frodo Baggins mass air flow sensor
GM went cheap on the battery cable terminals. Replace them with mil-spec style. Also, the H3s have problems with corrosion on the underside of the fuse box which puts the entire vehicle into an erratic "brown-out" condition.
The orange wire to be exact
my h3 was staling when it was at idle and hot out , engine light never came on..i fixed that issue by cleaning throttle body flapper, like dave haag had suggested.
Hi, I would check your timing chain assembly, sounds like it's loose and hitting the timing cover. A loose timing chain can throw the engine out of time and die.
Common on GM/Izuzu made motors. Change the VVT solenoid, change the oil, clean MAF and throttle flap. Runs like new.
I was about to say the same thing. I drive a 06 and it does same thing. I did exactly what you just said and runs like new again. Now I know if it get that RPM up and down crap I know the throttle body needs clean. In a years time I've clean it twice. If your hands on like you or I. It's a fun job when your bored. Hey babe what you doing today. Me; oh I'm going to clean my throttle body real good today LMAO. Woman; what🙄🙄. Honey never mind. Her; oh ok lol. Fyi little humor LoL 😂. But nevertheless all jokes aside. Your correct 🤷🏿♂️👏🏿👏🏿👏🏿👏🏿.
What’s the VVT solenoid?
@@MrJruta Variable Valve Timing solenoid
@@vanblindguy4600 thank you
My H3 had a similar knock sound also with camshaft sensor errors. Run a quart of Synthetic ATF for a few hundred miles, change the oil and add a quart of Marvel Mystery Oil, and the Problem went away. For my situation it seemed to be stuck lifters from gummed/gunked up old oil. It also solved my Cam Sensor issue (due to gummed oil on the sensor).
Will give it a shot. Thanks.
Tried your solution and the video is coming out tomorrow morning. Mentioned you in the vid. Thanks for watching.
Just swap
Yeah I got to h307 and it's doing the same and I thank I think I'm going to check the timing chain and it's got a balance chain in the back of the moto
I have exactly the same error code, with the difference my engine runs nice, no knocking sound and it doesn't die. So far, I've been done the following:
- Oil change
- Injectors cleaned
- MAF sensor cleaned
- Replaced Crankshaft position sensor
- Replaced Camshaft position sensors (both)
- Replaced Crankshaft position actuator solenoid
(with an OEM AC Delco)
- Engine starts easily right after turning the key and even remotely with an aftermarket alarm remote control
- No engine odd rattling noise, so I discard a timing chain issue
- No rough ridding
- Checked crankshaft position actuator solenoid after a long ride if it has any metal burr and it didn't
- Cleaned all sensor connections with electrical cleaner: Crankshaft, camshafts and solenoid
- I clear this code with an OBDII scanner and appears every time I re-scan.
In a few words, engine runs normally but this engine light is making me nuts because I want to scan the ECU every chance that I have to make sure than any other error comes up, any advice?
I wish I could help you. I am still fighting mine. Changed out all of the sensors and then the engine blew. Had a mechanic look at and he could not figure out either. I am to the point of just putting in a new engine, however I am worried it will just do the same thing. If I find out anything will definitely let you know. Thanks for watching.
@@SimplybEpic which engine do you have. The 5.3 spits lifters from the fuel mgt system. Does it have a miss as well ?
I'm not sure about the noise but I think the engine shutting down and the car shaking and running really bad is because of something called "reduced power" which is a really common problem on the H3's. You can search about it.
The fix for that is cleaning the relay and fuse terminals… in most cases
I had the same issue with a knock. It was a spun rod bearing on number 5 piston. The knock is most likely the piston hitting the head
Yep. 4 out of 5 bearings gone. Had it rebuilt and all good now. New video coming out today about it and finishing up the project. Thanks for watching.
The throttle body need cleaning but that knocking is a rod bearing!
It sounds like it needs the variable timing solenoid replaced. It is on the exhaust side of the engine, toward the front and is held in with one 10mm bolt. It will throw various codes when bad. Sometimes the screens on the solenoid get choked off and it only needs cleaning. I Run full synthetic oil with a good filter. Mine has 300k on it and I pull the VTS and clean the screens every oil change. It about a 5 min job.
Its your ignition switch sensor. Pass Lock failure will cut your engine off
Who is this fixed?
Well all engines have what they call a knock sensor and it tells the computer to advance or retard timing though what they call a cam phaser found on the end of the cam shaft and this is your problem. The rod knock is causing this stall. I work for GM and have been for 30 years and my H3 had this very same problem. Now all that being said it's time to make this a Alpha truck.
Thanks for the comments.
My 2007 had same knock. Had to replace engine
I’m in this phase but I’m so skeptical about taking my car places. People are sketchy with hummers
@@josephthompson9328 In the same boat. Something about H3’s absolutely fascinates mechanics and they get real sketchy.
@@urisquirt im actually having mine done having to wait for the motor to come in about 6500 bucks for it and to have it done mechanic said it broke a rod or bent it it made the same noise.
wow i hope you got it for a deal! i've seen H3's around here for $6k in questionable condition but still running (barely).. avg for one in good shape seems to be $20k, was hoping to find a fixerupper myself for a deal , love the vid!
Thanks. I think I purchased for around 4000 from CoPart. Then I put another 8000 into it. Was a really good project. But I sold it and bought my daughter an H2.
Sounds like it jumped a tooth giving that reading , that knock was the camshaft jumped 1 or two teeth . he could have saved it by replacing the timing chain with a timing chain kit , front and back includes tensioner . when ever you hear that knock shut off immediately, timing chain is stretched and will jump out of time destroying the valves. Stalling is map sensor dirty or needs to be replaced
Thanks for watching. When I rebuilt the engine, 4 out of 5 rod bearings were bad. Someone ran it out of oil before I purchased. But, have a new engine now and she is running great.
This is what mine was doing with the engine, ended up shearing all of the bearings
After changing all the necessary Sensors , i would do a Compression Test , and see
the Results , and maybe a Leak down test too , to make sure Engine does Not have
Mechanical problems such as oil leaking inside the Combustion chamber or Anti freeze
leaking inside the Head cylinder and combustion chamber [ there is a Liquid Test
that you fill up the Tube and put it on the top of the Radiator cap [ first take out some fluid
from the radiator cap , to have some empty space as not to touch the Tester's
Suction Tube ] , then pump the top to see if the color of the liquid turns yellow which
is the presence of Antifreeze in the Head cylinder ] ...Did you as well change the
Variable Valve Timing Solenoid ? [VVT ] ....
Or maybe if you have found the problem please let me know in here , thanks .
Change oil as often as you can [ once a month ] never use FRAM oil filters
they cause deposits on the Engine , they are the worst Filters in the world ,
next change all the car's oils , such as front and back Differentials , Transfer case oil
and finally the Transmission filter and Oil , PLUS the Water Pump , Thermostat ,
and for NOW ! hehehe , the Thermostat Sensor ...
Adding Marvel Mystery oil to the Engine [ not all of it but lets say 400 ML ] can
keep engine healthy , i would also add full bottle for the Gas tank to clean all the
pipes clean and Lubricate the Gas pump .....
Worst thing is that you may Need another ENGINE all together .
Sorry to be so offtopic but does anyone know of a method to log back into an instagram account?
I stupidly lost my login password. I would appreciate any tricks you can give me!
@Thiago Mitchell instablaster ;)
@Ellis Cairo Thanks for your reply. I got to the site thru google and im trying it out now.
Seems to take a while so I will get back to you later when my account password hopefully is recovered.
@Ellis Cairo it did the trick and I actually got access to my account again. I am so happy!
Thanks so much, you saved my ass!
@Thiago Mitchell You are welcome xD
Sensors will make these h3 vehicles act all kinds of stupid. And the BCM is basically garbage in them. Not throwing shade on them they’re great little snow trucks and great climbers. Towing isn’t terrible other than the mirrors and tiny windows. The dying is a number of variables. Be aware that if it gets the dreaded flashing check engine light and starts rattling like it’s about to explode stop driving it and replace the spark plug and coil pack and if that’s not it look forward to injectors. They certainly require a lot of maintenance if you daily drive them. But the cam sensors they have two one at intake one at exhaust side. The oil sensor is accessible from the top without removing anything it requires some reach. The EVAP Thing can give a fuel cap light if replacing the cap doesn’t fix it and the hoses are good it’s likely the purge valve solenoid. I can list all sorts of reasons they’ll act and sound that way. But again not hating on them I know this because I have one of these as a daily driver and it’s a constant project to have these once they’re older. Definitely a interesting vehicle and good 4x4 but it takes a lot of care to make them reliable and maybe buy back ups of all of the sensors and just store them in it because it’s always bound to happen when you’re far from home. What’s under the engine cover that has the vortex logo is the coils and plugs. There’s a spacer you’ll need to get for your catalytic system otherwise it it eventually always throw a code for it because once they’re older the sensors don’t detect right and the spacers are cheaper than replacing the converter.
Hi Richard hope you are doing well. I have H3 Hummer 3.7 motor block broken and I bought motor colorado 3.7 same 5 cilindros so should the computer of hummer can be used for that motor colorado please help me I in Mexico and lot of problems with Mechnic
Thanks for video make me rethink about this suv
Diều Hâu it’s a great car just this guy doesn’t know shit he should of never let the car gets to this condition in the first place
I agree but it would be the original owner. This dude bought it off copart.
How many miles are on the engine?? High mileage or Low mileage???
I have a hummer h3 2007 if the transfer case motor goes bad will this cause the vehicle not to go into drive gears its all will drive 4 will don't work its like its in neutral
Yep. Sounds like transfer case. H3 do have a neutral and if in it, the truck won’t go anywhere in gear. Are you still getting power to the actuator switch above the radio. Does it say it’s in 4 or neutral. Thanks for watching.
MAF. Mine did the same. Cleaned it problem gone.
Will give it a try. Thanks for commenting and watching.
S. Vance hey buddy i have the same prblm and i didnt understand what thing have u cleaned? Can u please explain it
@@jaipalsidhu9791 I cleaned my mass air flow sensor. It somehow got oily residue on the air sensor wire and made the vehicle run terrible and times not even start.
That knock sounds like it is a motor mount. I had the same noise in my 06. Replaced it and never had noise again. Was passenger side mount I replaced.
Motor mount HAHAHA... MOTOR MOUNT... I can't stop laughing! Yea because motor mounts have all those moving parts inside them. Ok you are not aloud to use you keyboard anymore you are on time out!
Have you done a video of you rebuilding the engine? I wanted to rebuild mine
So people here seem to think the Alfa is a less troublesome engine than the I5. I am looking for a H3 and I can't decide which to get. What is your opinion? I can easily rebuild a 5.3 but the 3.7 is more complicated? Help please
Robert Skillings I would definitely go for the Alpha. Probably more reliable, more power and about the same gas mileage. The 3.7 is a little better but I would personally would still go for the v8. I bought this one out of Copart so took what I could get. It was cheap with a clean title. Al still thinking about a conversion to the V8 but it’s expensive. Thanks for watching.
That knocking tells you a valve is hitting or a spark plug is broken inside a cylinder sounds like a valve is hitting a cylinder
HUMMER AASIF LIKED THIS VIDEO💪💪💪❤❤❤
Thanks.
Cant believe you are not pulling the engine out with it knocking like hell
Steel Mill I have done more digging and looks like it may be a timing chain issue. I think it jumped a tooth and got everything out of whack. Will have a video on this soon. Thanks for watching!!
I don’t mean to be negative, honestly. But, this video was like watching the video version of Facebook. Just 23 minutes of you explaining YOUR personal issues (mostly) without helpful information for the viewers. I deleted FB 5 years ago because I didn’t care about the constant updates on what my niece bought at the grocery store or that a co-worker went to a water park last weekend. Have not regretted that decision for one single second. Again, don’t take this negatively as perhaps a routine Channel Follower may find this “life update” interesting. Your channel so you are totally the captain. God bless to you sir.
Is the tensioner hitting the clutch fan???
interested to find out. cant learn enough about a truck you own yourself! sorry, i have no idea what to tell you
Did you figure it out? What was the problem?
What year is your H3? Are these issues attributed to a specific year or is it all model years from 2006-2010?
My radio turns on and off is it the battery?
Maybe. Could be a short though in your radio wiring. I would check your ground terminal to the battery and make sure it's tight also on the other end, usually attached to your engine or frame for a ground. That would be first step and then if still happening, go into the radio wiring harness and check for loose or chafed lines. Thanks for watching.
The issue i belive from oil pumper that not able to pumping oil to rntire part of engine !!!
Entire
That was the issues with my sis hummer h3 the oil pump inside the engine went bad so it was not pumping oil in the engine and starved the engine of oil
the car is automatically shutting itself off as a good cause so it wont damage your engine, check your PVC valve, also soon you will be removing the seal from your Damper cause it will brake, clean off your PVC
Yeah NO shop would put my H3 on the lift because of the weight
Sounds like some weak lifts
Clean that throttle body and that mass air flow....helps a lot.
Sounds like its about to blow up any ideas on the knock yet mate ?
Interestingly, just got word back this morning from my mechanic on this project. Not good. Will be doing a video soon about the results and plans. Stay tuned. Thanks for watching!
Epic Cars thanks maté yeah would be good to see what he says
Where the hydraulic oil is made it is clear they add colors to it for different types of applications like transmission fluid they had a red color to it it's still hydraulic oil
Would have been nice to really know what was wrong with it
That would help me more then all these guess
But since its the guessing game my guess is timeing jump and driven way past the point of no return fixing it
Less a new or used engine to heck with a rebuild.
I will have an update video coming out soon. Actually in the shop as I type this and supposedly out in the 20th. Will give full details and will be happy to get it back to start upgrading. Thanks for watching and commenting.
Throw a 5.3 in it like my Alpha.
Thanks for watching!
Need some 6.5L videos.
Rod knock.
Sounds like you blew up a spark plug in a cylinder or a valve is broken somebody put in wrong oil threw timing off oil too heavy.
Hi! dear; what type or brand of your OBD tools using to scan the code?
I don't remember the brand off hand but it was a few hundred dollars so not a cheapy one. My mechanic uses a Snap On scanner and got the same codes. But, just had the engine completely rebuilt and will have a new video coming out soon. Thanks for watching!!!
Maybe bad fuel pump / fuel filter / fuel pressure regulator
I haven't finished watching the whole video yet . but I'm going to think that when the camshaft sensor went bad that the camshaft was out of line , and something under the valve cover went wrong . and I'm assuming it's probably a bent push rod. either that or a broken push rod... most likely a bent one , and that's what's making all the noise....
try changing the oil i have a 08 it made the same noise
I wish that would have worked. Had to rebuild the engine. Take a look at my later videos and it shows all that I had to do to get it running and driving again. Turned out to be a great project in the end. Thanks for watching.
is the amazon the web-site to buy needed car parts for my Hummer H3?
and sir, if you can manage to solve that problem, please take the video and reply me the Link
Bielle problem ,bad oil pump
How many miles does it have ?
Found a 2006 h3 with 126k miles for 10k is it worth it ? Its at a ford dealer not a side of the road kind of place. I dont think it means much i guess maybe i can trust an actual dealer then a shade tree on side the road. I just want to make sure im getting a good reliable car.
All I can say is that they are great cars. I really enjoyed mine and that price may be a little high but seems reasonable. Get them to throw in something (maintenance, warranty, new tires, etc) and you should be fine. Thanks for watching and good luck.
@@SimplybEpic im gonna pitch um $9k out the door tax and title see if they bite. I just totaled my lexus gs430 and i got $12k for it. I was looking for something different and i saw this one. It has a new set of tires with 20 inch fuel zephyr wheels. I looked up wheels without tires are 2k. People here in New Orleans don't buy off road types of trucks and with gas prices so high i think i can talk um down to at least $9,500 out the door.
@@sonnyvito504
Hi Stephen, I just bought my 2006 Hummer H3 3.7 5 speed manual trans with 130,000 miles on it in the Eugene, Oregon area 3 months ago for $10,900.00 The price was a little bit high. but mine was real bad ass looking White and Black with 305/70R16s on it (none of the cheap plastic Chrome on it) ...
and I would not buy an automatic trans. I'm a retired Over the Road Trucker and
I really love driving this beauty !
Sounds like a bad coil !
Where can I find that instrumental I love ❤️ it great vid
Epidemic Sound is the site I use for music. Not sure which song this was but will do a search and let you know. Thanks for Watching.
dude that the engine lol my sis had the same problem but we got is a Chevy colorado 3.5 engine its the same engine and it fit right in wa way cheaper then a hummer h3 engine
Hummers are so iconic. I love them, especially in this grey color!
I recently found a POV with a black H3, and I am seriously considering buying one. I hope I can still find one in good shape. If you guys know someone selling a black one like the one in the video, let me know!!!
th-cam.com/video/WUl3QmCqlCs/w-d-xo.html
Keep up with these great videos! Maybe you can get the chance to make a video with the new Hummer that is supposed to come out this year or next year. That would be an awesome video!
Hello, I am from Dubai. I have a Hummer H3 and I suffer from a little high temperature in the text. Do you have what should I change in it so that the temperature drops below the text
Make sure you have fresh 50/50% Dex-Cool and consider a cooling system flush before the fresh coolant. Thanks for watching and hope it helps.
Lifters most likely
What year Hummer?
2006
That's probably the timing chain really loose and needing changed
Alittle bit of alot of issues. Timing Chain and Rod Bearings. Had the enging totally rebuilt. Have sold the H3, but got an H2 in it's place. Thanks for watching and commenting.
Please please please do not start that engine again get a mechanic in there and see what's wrong before you have three engines good luck. I'm sorry to say that the check engine light is the least of your problems
Broken timing tensioner ?
I am definitely thinking it is something to do with the timing chain. Thanks for watching and hope to have some solutions soon.
👍🔥
Rev it up higher please.
Oil pump failure
That’s the engine
Hate to be the barrier of bad news...but, that's a BAD rod knock! You need a new engine. Sorry...
4 out of 5 bearings were toast. Watch my other videos in the series and you can see how it finally turned out. Thanks for commenting and watching.
Maybe off timing
ahhh, the sweet smell of hydraulic fluid. It's got a damn auroma unlike anything else!
other than death itself.
Yes, that was a fun time cleaning it all up. I am idiot sometimes......well, most of the times and this time was a classic.
@@SimplybEpic listen buddy everyone that has ever serviced their own vehicles has experienced this in some form or another! no worries!
Bad timing chain
I am leaning that way also. At some point I am going to dig into it and fix myself. Mechanics just want to put a new engine in it. Don’t want to fix anything anymore. Thanks for watching.
@@SimplybEpic whenever you get the problem figured out please share it so that others will know how to fix theirs!
That does not sound to promising
Jeremiah, oh it wasn't. Found out that 4 out of 5 crank rod bearings were gone. Had the entire thing rebuilt. Ran well after that. Thanks for watching.
God did not make you break the hose.
Thats a diesel riiiiight😏
I wish. Sure sounds like one doesn’t it. No, that’s the sound of 4 rod bearings going bad. Have since rebuilt the engine and all is good. Thanks for watching.
Is like this guy was waiting for the engine to stop working the whole time lol 😂 does he really asking why the car is running like that lol 😂 the engine is dead get a new one brother
your a knock sell it for parts
Rebuilt the engine and drove it for about 6 months before upgrading to an H2. Thanks for watching.
co- part robbed me of 10000$ Never recieved title. Engine was swapped to base model instead of high performance one, the main reason i bought the car. Vehicle was flooded.... was suppose to be able to drive it... yeah right. it was a complete scam never again...stay away from junkyard vehicles ...there is a reason why they are not at a dealership.
