Hi, sorry for the delay! What is happening with your vehicle?

Hi, I really do not see myself as a teacher. I am just sharing information to help people. I hope my struggle with my smoking addiction does not limit the help I offer. Thank you for your concern.

Sorry for the delay! Did you do a OBD2 scan or read of the codes? Many thing can prevent it from starting. Crank position sensor, seized/bad alternator, fuel pump, etc. The codes may help us to figure it out faster compare to going component by component.

This comment is now pin in the comment section!

I have a Cosco battery: Group size 24DC, Cold crank at -17 degree 550 and cold crank at 0 degree is 685. The item number is 207200. I don't have the battery holder in my H3, so I'm not sure if it fits within the original battry box.

@@kevinthompson7694 Hi! Here is a link to a shorter video that covers only the process of resetting the TPM. If you have problems in the process or need more information watch my video or request help in the comment secton! czcams.com/video/Oa_LcnB5_L0/video.htmlsi=-oZf50NG_jXQN_0N Hope it helps!

@@reedron seems like the control module is working. So either the motor is turning but maybe doesn't get enough juice to move properly or something is preventing it to get in gear. If the fork was broken clean off, you would see the bottons switching correctly, per example 4x4 low, but you would stay stuck in full 4x4 within the transfer case. Best bet would be to unscrew it and try to see how it behave when you click the bottons on the module. It would show if it is the transfer motor that is behaving wrong or if it works well you need to drop your transfer case and check in it to see what ia going on. First let's pop that small motor, it's a cheap diagnosis. Do you have someone who can help you?

I'll ask a few questions to help me try to figure what could be the problem. How was the idle when driving? Did it feel as if the engine was strugling to move? Did you do any OBD2 scan to get a codes? (To scan you can use a 10$ scanner to get the codes). Do you have a sunroof/moonroof on your H3. There are a few things I can say to test which doesnt cost anything. 1: check oil level in engine, if low the engine can land in limp mode. 2: remove the throttle body and air box. Check the throttle body. If it is blacken and full of residue it will need to be clean. 3: if you check the intake air warmer box. There is a short hose that connects on the intake manifold. That hose can crack or become loose. It will make the idle barely impossible to run. 4: if you have a sunroof, is there water building up in your sunroof? You can open the sunroof to check. The side pillar plastic cover can be remove to check if water is dripping due to the build up of water. If the carpet is wet, it can be another sign of water build up. It cause humidity in the ecm connection. Sometimes just cleaning the sunroof drains to prevent future problems and disconnect the ecm to let the connectors dry it could hopefully fix it. I'll give two links below for the small hose and how to reach the throttle body. Finally, last question. Did anyone work on your H3. Repairs, parts replacement, maintenance. Anything. A loose battery terminal (connection) can do that.

Here is the video for the short hose located on top of the engine: czcams.com/video/AidQa7VZ2do/video.htmlsi=bMHn0j7v0W8eA8WN This is the video that shows how to clean the sensor and throttle body. I mostly want you to check if it is in dirty: czcams.com/video/dPsy4U6hM8U/video.htmlsi=2ZmLGYfUBnryvF2q

@@trevino9136 there could be a few things. I always ask to see if there are any codes that pop on the OBD2 scan. Beside that the injector fuse or it could be the anti-theft systems that is still on.

@@probonomechanic no codes, when i insert key and turn it the security light blinkS doesn't go away i was thinking it was a security issue i greatly appreciate it u the man

@@probonomechanic 1 more questions does ur fuel pump prime when key is turned to on not run

@@trevino9136 if the line is already prime it will not make a sound. If you tried to start ot often you may need to clean the spark plug if they are full of unburnt gas. Cleaning the spark plug will shownif you got gas in the cylinder and help to unflood the engine

If you put an 5efa engine, did you try to do a quick OBD1 scan for codes? An OBD2 scanner could work depending on the year of the wiring harness and year of the ecm. Anything under 1996 is the OBD1 connector. 1996 engines and earlier (1996-2024) os OBD2. Try with a scan first and check the codes that pops. This could help to narrow the possible problems here.

@@DOSdaze I can confirm that you are not a fool. My H3 give me constant problems where I need to leave my key in the ignition for 20 seconds before it reconize it. And now cars use your cellphone as a proximity key.

Glad it help!

I just saw both of your messages. Where you able to solve the problem?

@@probonomechanic no got me stumped good I changed the relay the starter and nothing I took out the ignition starter switch cleaned it greased it and it started up first turn lasted about a week so swapped that out and nothing at all it bump starts but I have to keep giving it gas to keep it running otherwise it wants to idle at 400rpm and stall

I'll give you an exemple. If the alternator is bad, it can still turn. But if you remove the belt, and you turn it with your hand. You can feel that there is a resistance and it will be harder to spin. In good condition, it should be easy to spin the alternator. Nearly no resistance at all. It is the same with the other pulleys and tightner. If you can't spin it easy with your hand, it mean it is seizing up. Does it help?

​@@probonomechanicoh ok so the stiff pulley is keeping the full serpentine belt system from turning over fast enough to start? It's like the engine is trying to spin but the stiff pulley is holding it back, therefore it's not enough to turn over and start? I think I understand now. Especially with these smaller engines and batteries usually on bigger engine with stronger batteries it can just crank right over and shred the belt on the stiff pulley but these engine are small with smaller battery so a stiff pulley can keep the crank from spinning enough to get it started? I'm going to take the belt off and check the pulleys.

​@@probonomechanichey one more question, if the pulley is giving too much resistance to allow the engine to crank over, will the compression be low also because of that or will it have the same compression?

What he means is you remove the belt and check the pulleys without the belt attached to see if the pullys are seized

You did an amazing job explaining the symptoms and the practical way of checking it

Verify the alternator first. If you remove the belt. You should be able to turn it by hand easily. If not, it is the alternator that new to be rebuilt or change

What a great video , Thank you so much

You're welcome!

You are welcome!

No, no, there are plenty of videos that are shorter on the subject on youtube. My video is general informations with the reality on what work and I what I do for these type of lock rings. I still suggest watching my video since other videos could make you believe that you are doing something wrong or at a minimum not buy a 100$ tool when a 10$ tool or plank of wood could do the job. All in all, feel free to ask question if you hit a road block.

Fuel gauge is not working? The replacement fuel pump have a new sending unit and it should fix it.

Any time!

Keep me posted on the work!

Just switched it out without an issue. I appreciate you man. Switched the pump and an injector

Anytime! I'm glad it helped!

You're welcome! Glad it helped!

Tysm for this comment, had the exact same problem. Worked like a charm, thanks again

No security sys.​@@probonomechanic

Ya, I really need to redo this video. At the time I wasn't expecting it to become an actual channel for H3 owners.

To reinstall just make sure to slide the hoses from the bottom and then attach the top part first. It will keep everything in place while you instal the bottom
