This video is awesome!!
Im 65 female, and I understand everything you're saying. I'll check my car in the morning & hopefully fix it 😊
Thanks heaps

Thanks a lot you gave me a peace of mind how to diagnose my vehicle not starting. Cheers to you bro! - from Philippines.

I appreciate how simple you make things for anybody, thank you!! ATM my car is having a hard start but I just watched it other video and is about to test it out! Thank you

[biturbo]

Josh is very clear to understand and logical..I reckon its one of the sensors on my car

[hengwang]

Thank you, this is very helpful. I would like to add my two cents here. My Mazda 3 was cranking but not starting, and the reason was a faulty mass air flow sensor. No code was recorded. But the culprit can be pinpointed by disconnecting the sensor and the car can actually fire using it's built-in dummy mode. Worth checking if the car hesitated to start, dropped in mpg, or had thrown a P0101 code recently

if hard starting first thing in the am or after it’s been sitting awhile, but it eventually starts; check fuel pressure regulator. turn key to ON for four seconds, then OFF. repeat 3 times. on the last time, turn to START. If it starts right up, it’s the fuel pressure regulator. If it still cranks without starting, look elsewhere in fuel or ignition systems.

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 gage 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 won't spark or pulse injectors, and won't throw a code. If your fuel pump fails on the road, try kicking the fuel tank as you key on and off and it might start turning again to immediately drive home or to a shop. I took a bad one out once, gave it a little rap on the bench, and it then turned with 12 VDC applied (worn bearings can seize like that). Most cars with a MAP sensor, instead of MAF, will run fine with a vacuum leak but will idle too fast if the leak overwhelms the IAC valve (it is fully closed).

This is the video I've been looking for! Thank you so much.

I've had a handful of problems lately, the main one is the mechanic

[mirsadmemic]

He is good. He is so good that this is just routine for him till others make rocket science from that

This is very helpful to me I'm working on 97 grand prix it's getting fuel pump is primeing should I pull line to see if filter is clogged

I just got a 2010 Sentra’s for $300 because the owner thought he blew the engine. Was cranking and not starting, lol I fixed it with a $12 pull a part air intake tube. The original intake tube had a big hole in it which messed up the air/fuel ratio and stopping the engine from starting lmao 🤣

brother very informative i been researching this for a month just to get all this information in such a clear form know i have a glimps of hope that my car will turn on at the moment im dealing with starter not engaging with fly wheel but ones thats good it should run in theory! checked everything else even learned how to check sensors on the way haha thank you subscribed right away

I just bought a used 2008 nissan xterra, 2 wheel drive. Ive only had it a week, and immediatelly it sometimes difficult starting it makes sounds trying to start but takes 5 - 10 seconds sometimes to finally fully turn on and engine run. But usually if its been running and only recentlly turned off, if i start it soon after it seems to usually start right up. I may be misremembering, but it seems to have more difficulty starting fully if its been turned off for a few hours or overnight. Guy who sold it to me said nothing about it, but i dont trust him at this point, as no way it literally just started happening the day i bought it from him. I had battery tested and its good, only a year and a half old.
And i noticed a slight fuel smell today inside the xterra while driving it.

Unfortunately i was told by oreillys auto parts when i asked about getting a new fuel filter that this model xterra doesnt have just a simple fuel filter that is easy to access and remove and replace alone, as its instead supposely inside the friggin fuel tank and has to remove the friggin fuel tank and replace whole fuel assembly and buy and whole new fuel assembly to replace fuel filter. Which is nearly $400 for just the part! What batshoot craxy dumb design instead of jjust having fuel filter outside fuel tank easy to access and replace like some vehicles..

And this xterra has a built in alarm system connected to a chip in the key, apparently. When locking and leaving vehicle apparently after getting a certain distance from vehicle thealarm automatically arms. Suddenly today when i drove to auto store and turned engine off and removed key, immediatley as i opened door to exit the vehicle the alarm suddenly went on making alarm noises for a minute. Had no idea how to turn it off or why it suddenly started alarming as i was still in vehicle with the key in my hand. It at least stopped alarming sound after a minute. Just concerned as it shouldnt do that and have no idea why it did or if its going to again and how to stop it.

So after watching your video and leaving a thank you comment and stating I'm a 65 you female....

I decided to buy a new battery because mine was considered old.

My car almost started, so I did what you said and changed the fuse, and my car started 🌞 but it's taking 2 turns of the key, so I'm wondering if there's more issues like the ignition. Getting late here, so I'll check in the morning.

[RobertHicks-uhzy]

I really enjoy the channel very informative completely I have 97 grand prix I've never changed fuel filter last week it acted like it didn't want to run so I took off tube for throttle body and cleaned it and it started but now it just won't start it's getting fuel pump comes on what can I check at fuel rail to see

[ToolsandTime]

Cool and useful video. Some very pragmatic information there, many thanks!

My 2006 VW Beetle was doing this after sitting overnight. It was a 5$ sensor "coolant temperature sensor"
Of course after spending 215$ for nothing, this 5$ sensor was the issue 🎉🎉

Hello, nice vid. I have a daihatsu sirion 2 with K3-VE engine and it stopped running all of a sudden. It cranks, but no start. I checked all the fuses/relays, they seem good. I checked the crankshaftsensor and it's giving me close to 2000 ohms. So that seems ok. I tested the harness with ignition switched on, no voltage. Any idea what that could be? I still have to check to camshaftsensor though. Regards

Great video! I like the way you explain what to look for. I learned some new things.

Also, it looks like you live in Hawaii?
