You are very thorough you don't jerk around and you diagnosed it right the first time. It is literally a process of elimination fuel, spark or air which is it.

Had the same problem as this video...and with the same results. VERY well done and informative. Even though I had gone thru most of the checks I still learned quite a bit. thank you.

I find your videos really interesting. I majored in auto mechanics some 20 years ago in high school. I chose to pursue other career interests, but long before that and to this day I still love working on vehicles, and your videos are a different slant on things, and after all these years I am embracing the "high tech" ways of diagnostics and figuring all this new age out. These videos help a lot. Keep up the good work and good luck.

Fantastic video. It covers all eventualities, right up to the diagnosis. Best channel on KZread for learning about how it's really done.

Great video. Thanks for your time and effort sharing your knowledge. You got what it takes to be a good teacher on this matter. Super, this will help me get my 1999 Suburban up and running again. Stopped working while it was parked with no so much use. A couple of more test but more than likely it is the pump. Although I can hear the noise when it energizes. I changed the Cam and Crankshaft sensors alerady... We'll see. Thanks.

You got me good this time. My wife & I were watching together and as soon as you said 03 Focus no start I looked at my wife and I said fuel pump relay because about 4 years ago we had an 03 focus have the same problem and I diagnosed it back to a fuel pumthe car ran good for a little while but then wound up having a major electrical problem that caused me to have to have the engine completely rewired so I took it to a shop a couple days later it caught fire driving down the interstate that's when I decided to open my shop so things would get fixed properly

You just proved that what my auto shop instructor said was true. "A no start should be the easiest problem to diagnose.", and the hardest, in his opinion ... driveability. Greatly enjoy your videos. The step by step logical path is extremely helpful.

@@SchrodingersBox How about a no electricity problem? any tips? Started as an "intermittent" clicking sound (?possibly coming from a relay/solenoid under dash near fuse box?) and electrical power off/on...(only had it for a few weeks) NOW ... that has just become a "constant" no power at all, ever. (open the door: no dome... Turn lights or hazards, nothing... Turn key nothing ..no power at all... (Except a faint red glow on the little red led near the hazard flasher button, but when keyboard turned goes out) ...and no more clicking either... all grounds tested good, (put jumpercables to bridge anywhere there might have been a weak ground too just to see) new battery, all charged up & good voltage ...but nothing...

I would start at the fuse for the circuit and if there is no power at fuse simply trace backwards from there. If there is power at the fuse trace forwards. It’s actually way easier if there is consistently no power. Is much trickier when it’s intermittent.

Great video very clear and con cise. Right to the point no B/S, my kind directions with a no nonsense tone. Outstanding. Thank you.

Really ,thank you for your extra work! I hope your channel will rise up!

Thank you for the tutorial! That car has a Fuel Pump Module, is a returnless system so the Fuel pump module controls the fuel pump with a PWM signal, that relay you are energizing will not turn the fuel pump on it will only send 12v to the module

Hello and nice work. For safety reasons, I feel that it is important to mention that caution should be used when applying power and ground to a circuit where there may be a likeliness of fuel vapor because of the arcing that takes place when electrical connections are made and broken. I noticed this when you used the Power Probe at the tank. It even appeared there may have been an evap. line or something that was disconnected in that shot. You also mentioned the tank was empty which would make this even more dangerous given the amount of vapor. In a situation like this where making electrical connections is a must, it may be safer to extend jumper wires a safe distance away from the presence of fuel and then making those connections there in order to gain your desired result. Please forgive me if this has been mentioned as I have not read most of the comments posted here, nor am I very familiar with YT usage in general. I am a subscriber to your channel, yet have not had the time to view many videos, but have enjoyed the few that I have seen. Your logic and perspective is a treat to see and I really appreciate how you provide the auto repair consumer with the same. It makes for better communication and understanding when they are in need for professional and courteous automotive maintenance and repair services.

My 07 Ford Focus is going in the shop tomorrow and I hope I have a superb procedure, all steps to check guy, like you are! Mine is intermittent starting.

Great video! Couple of Questions if thats ok? 1. Did you only check for spark on 1x plug? 2. That spark plug tester light would show spark in the leads.. can the plug itself still be bad? 3. Can I use my 12v car battery, connect to the Fuel pump directly to see if it powers on? 4. I have a 2001 Isuzu Rodeo 3.2L V6. Where's the best place to find what replacement model/serial etc.. pump I need ? Thanks :)

im a good mechanic i have a page on facebook and i get lots of bussiness as a mobile mechanic. i sprayed starter fluid in the throttle body and the car started just fine ran a few minutes and died im going to check the fuel pump by taking off the fuel filter underneath the car and then turn on the key if the gas dont come out of the fuel tank then its the fuel pump. but of course ill check all the fuses before replacing the pump. after i check the electrical if the pump dont work ill change it out and that should fix the car. 2003 ford focus also has a starter relay fuse in the box next to the battery and if you change it out it could also fix the problem. but im sure its the fuel pump because the car was being driven and it just died. it starts with starting fliud so that tells me its the fuel pump. blevins auto repair on face book alturas ca

Very helpful indeed! I often have people asking me, 'how do you know so much about cars?!'...i answer back "I dont." Logical deductions, educated guesses, process of elimination. Air, Fuel, Spark. The only things a typical car needs to run properly. Intermittent, all the time, when did you notice, etc are all basic questions that eliminate almost 90% of what the issues you'll test could be. I get Chiltons for my cars but for the most part just start tearing into things....videos like yours have been my education for years and I've even made plenty of my own 'how-to' threads on forums similar to this... to hell with the haters, they'll never amount to anything car related and if they dog do-it-yourselfers in videos like yours, they're not really the enthusiasts they claim to be! I stumbled across this video researching my 2016 Focus ST (performance stuff), but glad i did. Cheers and keep on doing what you do!

I just had a no start this week on my Mazda 3. My fiancé would turn the key and nothing would happen. The cabin light wouldn't dim so I had a feeling that the starter was not getting power. Quick check of the wire lead me to a bad starter. A few taps on the starter with a wrench got it going enough to get it home. Before I even thought about calling the part store I performed the voltage and resistance checks to be 100% that the starter was the issue. Used your technics (minus the power probe, which is on my list by the way) and confirmed the wiring was not the issue. Changed he starter and it's been running great.
