How To Diagnose Cranking No-Start Conditions 

Training starts @ 13:05

Quick pre'fuel injection story. Back in the early 80's I was making a delivery to the D/FW airport and driving a 1972 Datsun w/over 300,000 miles on it; original engine and had never been opened up befire. Our trucks always had oil changes every 3500 miles so they lasted forever. Anyway, Im on one of the side roads at the airport and the engine dies. I crank it over and it sounds like it wants to run but doesnt. I pop the hood, open the air filter housing, crank it over and the engine runs. I think great, put the air filter housing on, as soon as I clamp the air filter housing on, the engine dies. We tow it back to the shop. Take the cam cover off and the camshaft was snapped in half. I was impressed w/that little Datsun. When the air filter housing was off the 2 cylinders attached to the oil pump and timing chain drive were still firing. Put another cam in it and the truck never skipped a beat; ran till we sold it years later. Engines are always fun. Throw in fuel injection and an ECM and the fun just never stops. Really enjoy your vids. You and a few others are great teachers ;)

I don't even know what to say other than "brilliant". Extremely educational.

Some of the best teaching video's on Automobiles around. Fantastic Job Mike and Crew.

I'm not a mechanic so I don't know why I watched this from start to finish, I guess I'm just curious what makes things tick. What amazes me is the wealth of knowledge you have for a comparatively young age. Seems like it would take an entire lifetime to learn such complicated systems. You're a great teacher

Wonderful training! Walking through your crank/no-start step-by-step thought and diagnosis process was really helpful. You are an excellent teacher. Looking forward to more of your instruction. Glad you're back.

Another great presentation!! Lots of people in the industry forget their humble beginnings and perhaps that's why they are annoyed by your method in this video. However the majority of viewers are thankful that you took the time to educate us from the ground up! Continue making tutorial videos for the general public, those "experts" really shouldn't be here since they know so much

Your going to make life a whole lot easier for a whole lot of people who struggle with this sort of thing. Keep up the good work !!!!

Thank you Mike. Good job. Have a blessed and safe week.

Great class Mike! That diagnosis was done in a few seconds of cranking and only equipment needed was my ears :D Now to find the cause would take a little longer but I wouldn't even charge a diagnostic fee unless they wanted me to find the root cause. Nice diag...Jumped time, bent valves, spit rockers and your right customer's repair choice .

Thank you and all your crew on showing us your knowledge, I really appreciate

Thank you Mike. Always enjoy your videos. Very educational! 👍

Pretty intense presentation with all avenues covered. Can be used as a reference video for any tech that has come to a cul de sac in his or her diagnosis, The range of tools used are awesome and every tech is covered from the novice up to the professional. Videos are too long when there is no content. This video screams content and is a credit to Mike and his team. Well done and looking forward to more exciting car problems.

Excellent class as usual. Looking forward to adding to my wardrobe this year.

Incredible tutorial ! Thanks for sharing your knowledge and skill .

Thanks Mike for you great class, I like to see again , regards from Spain

Excellent vid Mike thanks for posting.

Great work on this video. Timely info for me. I just sent a contact us email to you guys on a hot start condition. I just got most of my gear together for my first laptop scope (Pico 2000 series the lowest mode). I just got my first waveform today. I will run through these test to try to fix my 04 Venture 3.4 that is just about to reach 200k. Thanks to all of you at Wells for putting together these wonderfully information packed segments. Thanks, John

Great video and excellent information as always. Appreciate you sharing your knowledge and experience with us!

Watched the whole thing end to end - great stuff as always, Mike! 👍👍

Thanks mike very informative video as usual

As usual first class presentation!!

Good presentation!

Superb presentation, Mike! The way you explain and handle tools and cameras for two hours straight... is nothing short of magic. One subtle mishap with Picoscope cursors happened and went unnoticed at 1:01:06 : you grabbed a cursor, but it didn't "catch" and dropped into 180mA zone. So you grabbed another one. Thus your cursors window made it seem like you have 176mA current, when it should have been more like 20mA. Which, of course, only bolsters your point of that circuit being a low current one. The thing is this issue happens to me more often than I want to, I wish it was a little bit harder to lose a cursor while it is being dragged...

Love it!!! Distributor, t belt... It's awesome that you post all your training on RU-vid!!! But but but....!!!! I'm sure you don't like when a vehicle comes in when it's hacked to crap from the customer!!!!

excellent video Mike thanks

Great class Mike! 👍 Sorry I’ve missed it!

Go Tech Mike Becker Good Afternoon take care and have a great day Mike Becker Tutorial great 👍 👌 👏 thank you From Nick Ayivor from London England UK 🇬🇧

Thanks good training

Excellent video

Very nice video!!!

Bro your video is amazing ❤ thank you very much 🌹

hi mike. always good info to know. awesome video

Top vid, it is shooty not being able to catch live streams because of the time difference but I always look forward to catching them after. Masterclass

Nice video enjoyable 2 hours.

Hi Mike. Man I'm sooo disappointed I missed it LIVE. You did and awesome job sir. As soon as you cranked it for the first time I wanted to see relative compression but was even more curious as to how it would look if all cylinders were low. I'm familiar with one low cylinder already. Now I know. Awesome. I really would have enjoyed being in the chat room also. Great people today. Fantastic job as always Mike. Looking forward to next months class.

👍👍👍👍👍👍👍👍👍thanks for the training video 🙏👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

Really good stuff

wonderful training on youtube.thanks

way to go !!! super amazing , excellent video man. Also, do you teach auto tech at a school?

Perfect excellent performance

Sir, you are the only one I know who can help me out with this car problem. The car is a range rover 1998 p38 4.6HSE and v8. Many people were invited to start the car even from a far State but the couldn't. The challenge is a crank no start, no spark,no injector pulse but good communication with a scan tool. I have added fuel to the intake manifold and crank the engine no change at all. It is not starting. In addition, I checked for spark, but there is no spark as well. Hence, I have just checked for injector pulse but there's no injector pulse either. There is also no ignition current to the injector circuit with key ON and engine off. All the fuses and relays are good. I also checked the injector circuit for continuity if the wire is shorted but it was ok. Scan tool communicated and showed only p1843 and p1842 code. There was no RPM during cranking. What I noticed today when I compared the ignition, earth and DC with the same car that was starting and driving to the car that was not starting, what I saw made me to flabbergasted. Where the was ignition for example in the working car there was DC in the car that was not starting. Also a particular relay circuit for example RL-2 one of the pin of the connector when my test light was on battery ground and relay removed, the pump buzzed and testlight dim but when I tried that same location with test light and same pin the test light was dim and ABS relay was actuated no buzz from pump. It is like that in many places in the fuse box and PCM circuit. Please what's the cause of the problem and what do I need to do to fix the problem?

Good job scanner danner

it's got a bicycle chain for a t chain belts last longer it's a cheater way to add vvt this is common on this engine great class like always

You should use your pico scope and do a relative compression test first. It takes a minute to do. Every driveability concern should start with a relative compression test imo. Another quick thing I will do is try to get it to fire on some brake clean or starting fluid. If you suspect broken timing chain/belt watch for valve action thru the oil fill cap ( not always possible). These 3 tests will take me less than 5 minutes.

Great video! Do you have any experience with changing the camshaft sensors on a Hyundai 2007 Santa Fe 2.7L? I have a crank / no start issue w/ zero rpm indication. I cannot remove the Bank 1 camshaft sensor (seems the engineers at Hyundai designed the water lines that go to the cooling assembly to encroach on ).

Very intriguing video, But, wondering about your use of a scope attached around the fuse testing the fuel pump... Is really helpful to be able to test the fuel pump when it's in or on top of the fuel tank and is not immediately accessible... - Is a scope necessary, or is anything possible using an volt/ohm/ammeter? - Related to the above question about using a volt/ohm/ammeter, if possible and measuring amps, then I wonder if a clamp-on meter can be used. - Are you testing only for bad/good fuel pump, or some condition? Or, maybe even if for some condition, maybe it doesn't matter if it's some condition serious enough to warrant replacing? Thanks in advance.

Hey Mike, good video! I have a 2.4 engine swap, dodge 2011 block ,08 head , in a 2015 dodge journey got it installed an it won't start ,throwing codes for crank an cam sensors malfunction, replaced all 3 sensors an still no change, took a scope an looked over reluctor wheel, looked ok, checked all relays an fuses, timeing to my knowledge is on ,looked over it several times unless there's something I missed, I'm lost on where else to look ,wiring to sensors looks fine unless there's something hidden, I put scan tool on Dtc an its telling me pcm checked out ok. I could use some idea on another place to look, Thank you

SWEEET VID 👍 👍 THANK YOU

great vid

Help please. We are just starting out. What would be the best Lab Scope Manufacture and Model to start with? We would like to buy the best so we can just add to it as we grow. Great educational videos, thank you for sharing your wisdom with us!!!

I've never seen that before. The roller mia crazy

Scanner danner never told usthat we can demage the pcm using a test light to check the controles. Thanks dude

God Bless You 😇🙏💖

If a late-model car won't start due to spark, it's usually a crank or cam sensor. If a car won't start due to fuel, it's usually a fuel pump relay or pump. Once in a while it's the wiring. Usually not the ECM or timing or compression.

I was called to another garage to fix a 2005 300c chrysler. The problems they noticed with the car was Hard or no start, red lightning bolt flashing, no throttle response, headlight stays on, battery and ESP light remaining ON during, most times immediate stalling after starting however, if it doesn't stall there's a rough idle throughout idling as a result a old PCM was replaced with a new one however problem still persisted. I scanned for DTC codes and saw a P0340, P2167, P2166, P2115, P2116, p0603 and more module codes like C2202, U0168, U1414, B1A25, etc. Please, how can I fix these problems? Can you also 🙏 provide me with the wiring diagram to CMP, CKP, APP factory values and how to test them? What should I be looking for in fixing the blinking red lightning bolt limp mode light, how can I reset the throttle without a scanner? 🙏 How do I fix that?

The engine oil appears to be super thin. Makes me wonder if the previous oil change included the improper viscosity of oil, which lowered the tensioner's ability to keep proper pressure on the chain. I don't foresee Honda specifying 0W-20 oil in an engine this old, if that's what was used.

Hello, Mike. What voltage is expected to see in a pcm controlled ground before and after the pcm provides the ground? Some type of bias voltage before and 12 v (Voltmeter on battery pos?)

Awesome video mike . Did the customer fix the car? what did you have to do to fix it?

Actually injection occurs while the cylinder is coming up to evacuate the exhaust gases, the pulverised fuel is kept in the port until intake occurs.

Good Evening Mike Becker Go Tech Timing chain should be replace 80,000 ,120,000miles on vehicles 6years On Timing belts should be replace 4years ,40,000miles or 100 000miles Well done 👏 Mike Becker Go Tech water 💧 Good for your body 👏 👍 👌 💪 From Nick Ayivor from London England UK 🇬🇧

Doubt it. Point is better. To do a pressure test in most cases to see what direction your are going. And then see if a scope is needed to be pulled out. I have also up sold pumps regulators and even some Injectors due to leaking. Wasn't the cause of their problem but it answered questions they had but didn't tell use about.

U guys should to do a video about no crank no start

first look sensor might be the best way to tackle these problems my humble opinion

09 jeep grand cherokee . it stops runing and it dont want to start. swap fuel pump and clean injetors . found the map sensor doty with oil and dirt. clean it and put it back and still tas the simtom

Mike a quick question.I have a 1.8 vvt engine .one cam sensor and crank sensor and two solenoids for the vvt.I have a 2 channel pico and would like to get a known good cam and crank corralation.Would i be better off disconnecting the vvt solenoids to get a better waveform or should i leave them connected?Also if done with them disconnected would it harm anything.Would like to see a vid on testing vvt with basic tools and advanced tools.Thanks again for the great explanations.

what I would like to hear explained is how does the transducer in one cylinder indicate a problem in all the cylinders.?

Yes please 🥺

What if you have fuel in vehicle but flashing low fuel help please

Tiguan 2014 Right hand side Back brake light dead, flicker light working. Tested not the light unit or globe. What is the control box fuse for the right break light? 25? left hand side break light working no problem? Please advise?

(I, don't have any crank and no start. I, notice that I've got 3 fault codes that popped up on the cluster. I, asume that 1 out of the 3 codes is keeping it from cranking and starting)

how can i sign up

(I, took a jumper wire to were the starter relay is at and sprayed 3 shots of starting fluid inside the air box then the car started up. I, need to find out what those 3 codes are that popped up)

I have a 2003 f150 5.4 engine can I manually inject fuel too straight to try to start the my truck

Can I manually inject fuel to try to start my truck

So by clamping an amp clamp around the fuses that feed power to injectors and coils you can tell which ones are firing and which one's arent?

I'm having the same issue kinda.. My Tucson 2006 v6 2.7 is doing that. This just occurred out of nowhere

Way to go . Have intermittent No Crank No Start on CLK 220 Cdi Auto car runs well smooth Tick over but can suddenly cut Engine while driving.?

about fuel : isn't old bad fuel also be a factor of a no start?

It normally take longer to do a fuel pump current test then it does a pressure test.

I used starting fluid to see if it will start and no start. Do I still need to check fuel pressure?

Hey, Mike. Will a car ever run without a crank sensor?

I'm have problem with the 2007 pathfinder nocrank

A faulty ECU may not supply spark and injector pulse signals. Replace the ECU. Been through this twice.

lift back seat up to get to fuel pump...how hard is that?

@19:45 thats some nice corrosion on the battery cable! Lol

Ignition lights not coming on

Low oil pressure may also cause timing chain issues.

Hi, what about the WELLS VE channel?

I wonder if it is wise to use an impact on a spark plug?

Would you take that motor out the bottom? You should show how that's done.

Timing

Cranking no RPM. WHAT WILL BE THE PROBLEM?

Hola mike clases en español porfa

what would you do without that computer?

very nice intro music dum dum .........dum-dump
