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.
this guys channel and yours are some of the best on youtube, been subbed to you both for over a year
i have been diagnosing engines exactly the same way you do since i was 14 , on top off it i sent myself to college and added a machining degree . I am impressed ,good job!!
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.
Fantastic video. It covers all eventualities, right up to the diagnosis. Best channel on CZcams for learning about how it's really done.
I love how straight to the point this guy is ! LOVE IT ! No BS, no silly sally dilly dally bs jokes or run around ! Love it !!! This is professionalism at its finest !
Migizzl Empires what does fuel at the rail mean?
Great stuffs

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.
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.
Hey Matt, just thought I would drop a line and tell you you are doing some great no BS Videos. You are doing a great service for us folks. THANKS ALOT BROTHER! keep up the good work!
Thanks for the heads up man! I'll keep on truckin!!
You gotta love the armchair mechanics who subscribe to this channel for the express purpose of thumbs-downing the videos as soon as they are released, and yet they still watch the entire video and learn about stuff that they have never done or will do.
Just sayin....
Schrodingers Box I know 1 person that would certainly do that for every one of your videos, not gonna name any names. :P
***** Hahahaha.... He's not a sub though!
Schrodingers Box He's on mine. I don't continually call him out though. ;)
***** It's no one subscribed to this channel that's all anyone needs to know.
Schrodingers Box Why would anyone thumbs down any of your videos? They're all informative, interesting and accurate. It must be someone who manufactures plugs, wires, and coils for a living and they're afraid you're going to cut in to their profits. LOL!!
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
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.
Had this before on a focus. ....dodgy connector on the fuel pump...they even changed the pump but neglected the broken connector which would works loose in a couple days...
Nice channel and diagnostic routine...subbed.
Excellent thorough diagnosis from one perfectionist to another
Ozzstar Can't argue with that!
Like the intro. My number 1 observation for fuel pump failures on identical vehicles is constantly running the vehicle with low fuel level. I only like factory fuel pumps or carter. The rest of the aftermarket pumps are hit and miss. 👍
Steve Rob That's exactly why I am waiting 5 days for the new pump--- it is in lieu of getting an airtex in 2 days, and then repeating this job next year lol
Schrodingers Box Sad, airtex used to make great pumps.
Derrick Hodges I always had good experiences with airtex,but I haven’t bought one in a decade. I wonder how Bosch is nowadays.
Thanks sir.
I followed your progress and found out that the wiring inside the sending unit was open after I was convinced that the pump was bad. So the best thing is put all possibilities up front .
Thanks again!
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.
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.
Realtime diagnosis was awesome, hope you do these more often-
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.
+pramponi I agree with your instructor very much!!

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...
(automatic transmission)
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.
You are awesome man! I really like your videos because you cover everything fluidly. Alot of guys leave things out. I'm subscribed as of now
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
just WANTED TO SAY THANKS FOR THIS VIDEO . i was able to get my girls car home last night after watching your video.
As usual a very good explanation how to make quick diagnose of a no start. And for a German like me your english language pronunciation is proper and clearly understandable. I watch all your vids and have already learned a lot. Thank you very much.
Thank you very much! I do get a lot of compliments from foreigners on my english!
Hi, just watched your video.Fantastic.Your fault diagnosis covers all the possibilities. Better than any manual.Keep those movies comin. Thanks.
Great job you are an amazing teacher
Great process! just curious, can you swap the fuel pump motor, use the old casing with the right slot pattern?
Yes
Thanks for you great work in this car and your very good explanations in all the process..just simple and usefull!!!...greetings from Guatemala City!!!
very informative the way you conduct your work ,not to much talk but a lot of information.
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
+James Blevins If fuel comes out at the filter how do you its at the right pressure?
+Schrodingers Box . i would use a fuel pressure gauge on the fuel bleeder on the fuel rail
You have a lot of knowledge mate. I’m a qualified automotive technician and you have a lot more knowledge than most that I’ve worked for or with!. Keep up the great work mate🍻
Much appreciated!
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!
Thanks man. You nailed it- almost every video is the first time I have ever seen a particular car much less the problem with the car. Its the process, not the experience that allows accurate diagnosis.
Please get a power probe i dont know how i managed without it.
Thank you...i have a 2002 ford focus....cranks wont start.
Changed fuel filter, spark plugs....im gonna do the starting fluid test today....awesome video keep it up
Dude, you are an absolute badass at diagnostics and you make it understandable as well.
thank you. My hope is exactly that- to make it so anyone can do it. And they can!!
Fantastic video. Full of information in a short amount of time. I didn't have to fast forward through any of it.
Now I gotta check an old car, 1989 Mercury Tracer with 401,000 miles on it, for a no spark. Just totally died while driving it. I need to see if you have a video on that. I purchased a new distributor & coil because they are a few days out once ordered. I need to diagnose before installing them.
Good job.
I was expecting spark. My Focus had an ignition control short to ground. The control line rubbed through insulation on egr tube and, of course, pulled down circuit and fried the coil. The coil had a big crack in its bottom.
Thanks for posting.
informative , direct , and clear diagnosis , Greeting from Saudi Arabia
Superb! Inertia fuel cut-off is another 'quick check' (for me). When I crank I check for a slight movement on the tacho - to 'quickly' verify the crank position sensor.
I love you man , straight and to the point and very well understood , we both think along the same level but you got me beat on some things , love your vids and i watch hous of them , god bless you and keep going
Tim Westminster ALL people with critical thinking skills think the "same". The difference really becomes knowledge, not thinking strategy. This channel is designed to give people such as yourself the knowledge to "plug into" your already existing critical thinking strategy so you can cover all the bases.
you right I follow your channel and you help me a lot. I do mechanic most are my cars or family and friends, you should have millions of subscribers you teach really good I just replace fuel
pump of my dodge 2500 v10 thank you for all your teaching
Another great video!
If i have a crank no start at work with no sounding fuel pump prime (vehicle dependent), my go to tools are usually a dead blow and a test light lol
dreamer2355 Nothing wrong this the dead blow test! But is it bad fuel pump or are you shaking up a loose ground to the frame? Still need to directly test the pump to be 100%
Absolutely! But if it starts, it makes it easier pulling it into the bay!
I loved your full in-depth video
Very thorough and clear explanation with high quality video
Matt, I bought a new Focus the first year they came out and in the next two years had Ford replace the fuel pump five times. Kind of like the Takada air bag story. Love your chanel. Dave
Great job well done step by step process for someone who say that he not a auto mechanic by profession did a fan good job ,I having the same came car problem but after watching this I comfortable I can fix this problem You get a five star rating
Thank you!!!
One of the best parts of this video is at 0:58 when the car comes off the flatbed truck. That is priceless. The next time it comes out of your garage it is diagnosed and fixed if the owner has the funds. Has to make you feel great.
Sandbag1300 Yes it is satisfying. That tow truck driver is Joe- coolest dude ever. My driveway is VERY sloped, he perfectly lines up the cars so they just drop right into the garage so I don't have to figure out how to push them up the hill. Most every other driver will just drop it in the driveway at best. Takes him longer but he gets regular business from me.
i think this guys video is just as important as all the mechanic video,s i watch. so please dont thumbs down mechanics, we are just as important to you as dr,s are to you, everyone sees a dr, and everyone sees a mechanic from time to time so be nice, if you dont think its right or you dont like this guys video you dont have to watch ,,
I"m having a no crank/no start problem but there is a fast ticking sound (from the starter). My problem is highly likely to be the battery and I'm waiting for a boost (my car had the windows open last night and it rained so a short somewhere probably drained my battery). In the meantime, I watched this video and I am so impressed with your skills not only with the mechanics but your ability to explain in common language. I would heed your warning and never touch the relays but I am learning about the general functioning of the engine. Thank you so much for your videos and I will subscribe and I've learned so much already.
Private Netizen Your possibilities for that situation are bad relay, bad battery, bad starter/solenoid or voltage drop at the starter. I have videos on all of these so solving your problem is assured.
I like your channel the best, great logical direction and results.
Really ,thank you for your extra work! I hope your channel will rise up!
Great fast clean diagnosis. Puzzled by the 17 thumbs down - I couldn't see anything wrong with your explanations and methods at all Matt. As the saying goes "you can't help some people"
+mrghiax Exactly. Many of the thumbs down are from "over the hill" professional mechanics that realized their vacuum gauge and dwell meter are useless in today's world and the fact a DIY can work on computer controlled vehicles frustrates them.
I see it all the time.
Others just thumbs down because the video is longer than 3 minutes.
And others, believe it or not, are just trolls that actually subscribe to my channel and thumbs down the instant I make a new release despite the fact they watch and learn from the entire video!
Please do more video like this. I'm new to your channels best of luck man.
nice vid, enjoy the clarity. Wish all on call outs and garages followed this 101 procedure. I usually teach my apprentices and staff to give the tank a few wacks while ign on or someone cranking,often pump will actuate and verify quickly a fuel pump fault. (of cause ensuring brake on and out of gear or in park!)
+Peter datechmen How do you confirm if the whacks indicate it was the pump vs wiring?
Simply brilliant. Absolutely... brilliant.
Perfect this is the most understanding video I see with all explanation from the beginning and finish thanks recommended
Great to hear!
Love your videos, very informative and to the point. I've learned quite a few things from you, thank you.
Thanks man!
This guy is awesome. Great video bud and lots of good info. Keep up the good work.
ARE YOU A TEACHER OR INSTRUCTOR IN YOUR COMMUNITY COLLEGE? CERTAINLY YOU SHOULD BE A GOOD ONE. YOUR VERBIAGE AND EXPLANATIONS ARE RIGHT ON POINT. EXCELLENT VIDEO.
Easy, simple one.
I've been here, anyway. ;)
BTW. Very nice call for voltage drop as one of possibility. I smiled at this moment ;)
you are the best and jimthecarguy and fordtechmakuloco your videos are the best tanks
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. Thanks for taking the time to make these diagnosis videos! Oh and GO BILLIKENS!!!
arcdraw That's exactly how I would have done it!
That's great to hear. I'm on my way to being in the 2%!
arcdraw Nope that is "has joined" to the 2%. You have arrived with DVOM in hand and for some reason a brown cardboard box?
Agreed with Mike! people don't properly diagnose things by accident. They may guess right, but not diagnose right. You clearly "get it" arcdraw!!
Thanks for the worm welcome, guys!
your work is shining bro.
Great diagnostic video as always....Thanks for sharing.
mikedevv1 Thanks Mike!
Great Video! You throughly explained everything!
Great video. Just subscribed to your channel. I am trying to educate myself on vehicle maintenance, and your videos look like they'll do a pretty damn good job. Keep up the good stuff!
kakalala09 Technically, I don't cover maintenance very much- mostly advanced diagnostics and repair. I only really have a few maintenance videos from my early days and I have since swayed away from that.
Another logical diagnosis to a problem. Awesome job, Matt.
wysetech2000 It's the only way to go, eh!
Schrodingers Box As a Canadian, I would say that's right eh! {:-)
wysetech2000 Or would you say it's "aboot right"
Well, maybe some of us.
I learned a lot from this, well done!
Brilliant Stuff Matt, many thanks for this. Regards Jay
Matt, the no crank, no starts are the best. Your viewers get to learn real direction so they won't make the incredible mistakes that neighbor did and waste a lot of that woman's hard earned cash! Great vid and congratulations on the 20,000 subs! Sweet!
Billy R Thanks Billy! I agree- no starts are the most fun- take a break from the scantool!!
Easter to drop the tank than remove the child seat. LOL I'm with you man! Awesome videos!
Great job,love your videos.very helpfull save me a lot a money and learn a ton with your videos,thanks for your valuable info
"If you're anything like me - and my apologies if you are...". I nearly jettisoned my English tea over my English monitor... Great work Matt, I can lose a lot of time on this channel. Time well-lost in my view.
Thanks for the teaching and your pacience for comunicate your knowledge brother 🙏👍
So nice of you!
I will never forget watching a video on CZcams of some guy ripping the back seat out of a Focus like that one and taking a sawzall to the floor pan, while saying "There's supposed to be an access hole here," thinking that the shape of the indentation was them forgetting to cut the hole...
Another awesome diagnosis! Quick, efficient, and methodical; exactly what I like to see! Amazed that the parts store gave you the wrong pump, though. Wonder what the deal was with that...
Lol Sawzall to the floor pan?? Gotta see that one lol.
Yeah the pump turns out that the wagon (this car) has a slightly different style than the other models. Parts store computer didn't have that info so ended up with wrong part. I'm actually not even 100% sure the one on the way is correct in fact!
Schrodingers Box Oh geeze, I hate that! Good luck man, and keep us posted!
I must say, that has to be the most adorable, tiny little fuel tank I've ever seen come out of a car... LOL
Forget the naysayers... awesome job!!! 😊
This helped a good bit for my 2001 my valve for my fuel rail is under the rail on the passenger side under that little bracket
Nice and clear............ wonder full job Mr:Schrodingers Box
Thanks for the video . It is a sound algorithm but for me I can't tell if there's a good compression or not because I am a biginner
Excellent diagnosis.
Amazing diagnostics keep them coming
More to come!
thanks man that helped me out alot i got my focus running thanks again
Thanks for the video, I learnt something today.
as always just awesome matt well done sir !!
+Chad Cohoon Thanks bro- Happy Thanksgiving!
Well done.
And congratulations on your channel's success.
GeekDIYMechanic Thanks Geeky!
Nice one working logically always works --- well we live in the real world so make that nearly always.
I was looking on ebay last week and came across a assorted set of special test relays that have a switch in place of the relay contacts. Not available from sellers where I live (UK) so I will have a go at making my own from old relays.
Good job as always Matt. I have a suggestion though that will save you some time in the accuracy of the diagnostic. When you unplugged the relay for the Fuel pump you should have found a way to tap off of the contact and coil side of the relay with it still plugged in. I know you put power at 87 and the pump didn't work, but you didn't get a true Voltage drop for pin 30 and 85 and 86 on the coil side. So if you had a problem on the feed side or coil side of the relay circuits you wouldn't see it because you are checking the wires with the relay unplugged. So if it was a problem on either of these two circuits at the relay base, you just pulled the tank down for nothing and wasted your time. Hope you don't take this the wrong way, just observing and trying to help. Been wrenching 18 years and have been around the block a bit, including getting my butt kicked on different problems, and learning from my mistakes. However I try my best to share my knowledge so other people don't have to make the same mistakes I did, and hopefully it will save them some time and frustrstion. Like what you have done with the channel, looks great dude.
What Juergen said. the power probe has a green indicator light when it makes contact, so I know for a fact I sent 12V towards the pump from the relay box. The fact the pump didn't run means relay box is eliminated- the problem is downstream of that.
The decision to drop the tank was because it was such an easy design. if I had to remove exhaust or whatnot, I would have gone to inertia switch and tested from there.
I understand that the pump did not turn on when he put power to the contact output. And I am in agreement with his thought process, it's just in the past I have encountered multiple problems with circuits and you need to Volt drop check all circuits involved that make a component work, that was my point. Another thing you could do to the relay if possible is take off the relay cover and see if it clicks when you crank the Engine over then look at the contact side output Voltage and make sure this isn't much drop between the contacts with a Voltmeter and with the relay plugged in. Of course you might not see very much drop at all in this case on the relay contacts because the pump is open, so no current flow, no Voltage drop. Unless the relay had extremely bad or corroded contacts.
Schrodingers Box I understand perfectly Matt, you were spot on there, it's just like I said in a previous post I have encountered multiple circuit problems before and you need to verify all circuits involved by doing a Voltage drop test with the relay plugged in. That way you know the contact supply wire is good and that the coil control power and ground is good. That way when you finish the job you know all circuits involved are good.
Had the pump started when I sent 12V to it, I would absolutely have been voltage drop testing those contacts. In actuality there wasn't even a need to verify the relay box at all if you think about it- I only did that because I was already there and wanted to promote my relay video lol.
Great video, thanks. Trying to diagnose no start on '99 Mazda 626.
Very HeLpfuL ! Thanks for that testing.
Tell me you a Car Genius without telling me you a Car Genius....👍👍
Im so happy I found your channel!! subbed
+stefan fann I'm happy too!
I do like the fast flowing format.
Tiit Saul Me too- I can see after 10 no starts it would be cumbersome to re-explain how to do the testing and what to look for each time.
Good video matt !
excellent channel bro .... a lot of great info on your vids.. cheers from a DIY garage fab guy
B Cage Thanks bro, welcome!
Great Video as usual thanks again for the TIPS!
great job love the way you think
Great Video !
I did until the part, from Carburator Starts and the 15 Amp fuse, now i see there more thing to test...but I dont know have that tool.
Can a Gas Pump during the night broken or be a Filter completeky stucked?
Because Focus mk1 reached home with no issues, next day no more gas intake to the Carb...
SO WELL said on the flat rate pay issue vs. "diag guessing" when the percentages are in your favor. Any full time certified tech faces that decision every single day. Once in a blue moon u eat one but you must use expediting guessing to bring home a good paycheck consistently. Thx. Great video too man.
To cheack the wiring intergrity from the fuse box could you put your test pen to positive battery and then to the load side of relay pin 87 and if you see it light it means the wiring is good from connector 87 to the pump windings and back out to pump ground chassis ?
this one is actually one of my favorite videos and fasttec video. you're good for a diy.
