This is the best vehicle related video I’ve ever seen.

Pro tip :
Watch the RPM while cranking, a little raise in RPM indicates computer receiving a signal from crank sensor. If the RPM is not moving at all then there's an issue with Crankshaft sensor or something related to it.

Super helpful. Just grabbed an obd2 from amazon because we have an old 2005 cavalier we are trying to fix up and it wont turn over. changed the whole fuel system. Pump, filter, spark plugs.... Still won't turn over. But your video now leads me to believe its an airflow issue somewhere so I'll check that tomorrow while I wait for the obd2 reader to arive.

Use your deductive skill and Spray starter fluid (ether) down the intake duct. If the engine runs on that the spark system is working, (crank sensor OK) so your problem is in the fuel system. Next step would be to verify fuel pressure at the supply to the injector rail (Screw gauge onto test port), then, verify fuel injectors are pulsing. If a bad crank sensor, I think the engine controller doesn’t even know the engine is turning over so it won’t spark our pulse injectors, and won’t throw a code. If your fuel pump fails on the road, try kicking the fuel tank as your key on and off and it might start turning again to immediately drive home or to a shop. Hope that helps but that’s what I did to figure out if it was a fuel issue or a spark/ignition problem. 👍🏻

Very good vid. You missed out one other probable cause and thats a fuel cut off switch that is usually in the glove compartment. They can trip if you hit a pothole. Thanks for this vid. Cheers. 🍻👍👍

THANK YOU SO MUCH! This is one of the best videos I have found on here by far. Very informative and easy to understand. I subscribed as soon as the video was over. Looking forward to whatever else u have!

I’m working on a 2000 Honda Accord 2.3L. Never had any issues with the car until recently. This baby has been a BEAST! 250k+ miles. Never once broke down on me. Ever. Started quickly every time. Drove smooth.

I had a massive oil leak for a very long time. I had to carry 5qts on me at all times. It was bad. I took it to a shop to see where it was coming from. They told me to scrap it bc it was leaking everywhere it could. $2500 quote to fix maybe 40% of the leak. I decided to look myself. I narrowed it down to the vvt solenoid gasket. Changed it and no more oil leak! $10 fixed what I was quoted would be $2500-6k.

My ac control head would lose power. I could wiggle the harness around and/or flip the control head upside down/sideways and sometimes get it to come back on, until it wouldn’t anymore. I got a used control head and had ice cold air!

After this I decided to change my plugs, wires, distributor cap and rotor. Might as well give her extra loving since I got the rest fixed.

Only after this have I had issues. It’s currently in my driveway not wanting to start. Last time it did this, after it sat for a week or so, it started. I drove it the other day and it died on me. I had to pull it home. Wife was in tears before it was over. Great times. (Not from me being a dick lol)

I first started noticing issues when I was using the air conditioner. Sometimes my rpms would get weird and act like the car wanted to die but wouldn’t. Then, all the sudden the air was only cold while I was driving. It may be my fan assy. I’m still checking into that. If the condenser fan isn’t working while I’m idle, I do understand it will cause the air to get hot. Just mentioning this incase it’s relative to the issue.

Very sorry this is so long. I’m hoping someone reads this and knows what my issue is. Can the ac cause the car to have issues where it will die and not start? I wouldn’t think so but I’m obv not a mechanic. After I changed the plugs, wires, dist cap and rotor, plus got the ac working is when I started having issues. I don’t think it’s the ignition parts bc I checked if I had spark and I do. Plus it was running beautifully. All the noises I heard before were gone. It was running silent. I don’t think I’m getting fuel. Is this a coincidence or did the load from the ac cause this issue to arise? I checked all my fuel pump fuses/relay and they’re good. No blown fuses, the relay clicks when I turn my key like it’s working. When I sprayed starter fluid into my intake hose, the car will start right away. Obv it won’t stay running more than a few second but it starts. I changed the fuel pump and pump filter last night. (Just the fuel pump, not the whole assy. My gas gauge is working so didn’t need the whole thing) and the car still won’t start! What am I missing? Noway all the injectors have failed all at once. Maybe I got a bad part from oreillys… it happens.. could it be the fuel pressure regulator causing it to die and not start? I stopped and got a fuel pressure tester to use tonight. So we’ll see if that helps me.

Sorry again for this ass novel 😬 💀 😂

I changed battery, starter, alternator, fuel pump and still cranking, and at the end i replace all sensors and after changing maf sensor it was solved.I didnt have any error on diagnostic or dash.

Friend's '02 Camry. Picked it up on the side of the road, crank no start. Throttle body was siezed, plugs are shot, threw codes for cyl 3 and 4 misfire before it died.

Got new plugs in, I flooded the cylinders, so those are drying rn. Tomorrow is a compression test. I fixed the throttlebody, it now moves as it should. I have air, fuel, and spark. Timing is currently unknown. If I can't get her going tomorrow, I'll hit timing next.

I have a 01' lexus GS 300 with an intermittent crank no start. Leaving me stranded often. I replaced crank shaft POS sensor and no deal. Had the idea to : change the air filter, clean the mass air flow sensor, and run injector cleaner through it. Once i did all that i no lobger get the crank no start problem. I was thinking there might have been a carbon blockage in the fuel rail or something but i really dont know.
Hope this helps someone

I know this is for cars that arent suuuper old BUT, I bought a project car from the 1980s that would crank but would not start. For those doing a project car that was not running and has no OBDll port try to first address the fuel system as stated in the video. Previous owner tried to get it to start and changed new spark plugs (checked by taking them out) and new distributor.I changed the fuel pump and fuel sender unit on my datsun along with the fuel filter. It wouldn't crank. I checked the fuses... didn't crank. I was lost until I took it to a mechanic and they found the battery was properly grounded. they simply moved the ground onto a metal part on the actual engine cover and BOOM it ran. I replaced the fuel injectors since it was more than 20 years since it ran and so far it was good. Most people don't mention a bad ground since they assume its wired correctly but to those who have a project car or a car that someone else worked on try that.

I think if we could all just pull the codes or would make our lives easier and we wouldn't need to research symptom. The codes I got before my ECU was reset due to dead battery but the codes helped me find my first problem. Now I have to find what issues the burned wire meet had free caused as such as frying the ECU or other electronic components.

[bribri]

Very important to buy a code reader they're not that expensive it will save you time and money if you work on your own car

[fouadelassal]

Great video. What if no crack to begin with ?

[brandongonzalez]

I had replaced my crank sensor because it was cracked and car started up let it idle for a while drove it around but when to turn it on again and back to square one

[anishkagihan]

Thank for the valuable information.. Its really worked 🙏🙏

[christygarcia]

I have a 2010 jeep commander sport 3.7 v6 engine & I just replaced the flywheel with the new original part because it had loud idle knock sounds but car was running fine before changing the flywheel so turns out I checked with an ob2 & got several codes in regards to issues of crank no start. So since I do know my way around vehicles to a certain extent I changed the following myself new coils & plugs, new camshaft & crankshaft, bought & changed new ecm, did a whole radiator flush & a catalyc converter, egr valve & fuel injector cleaner, new oxygen sensor, new starter, I took off the map sensor cleaned it, checked my battery & alternator, the fuel pump & oil pressure, the plugs & coils have spark, the crankshaft & camshaft are working good as well the truck has gas too but still crank no start the only thing I need to check now is the gas fuel filter to see if it's not clogged to replace it with a new one & checking egr valve see if it needs replacing but other than that idk what else to do on it any ideas on what it can be everything I've replaced is new & are original parts since it's my daughter's truck I Love working on the little stuff myself everything except for motors & transmissions lol but please let me know what you think it could be thanks🙏

[louisville]

TRY THIS FIRST!!!! I had exact same symptoms but I just disconnected positive from battery and reconnected (reboot computer) just worked for me 2017 transporter. 😅

[antonionguenha]

Can you tell me where to get the tools that you are using and they're names please

2005 Toyota Camry 6cy I have a major coolant leak coming from the side where the water pump is at. Im not sure if the car overheated as my mom was driving at the time. Car won't start it cranks but won't turn over.
