I'm impressed you decided to post this considering the outcome. It says a lot about your character. I'm always looking for the next video. Thanks man.

That is what I like about Ivan T, a real straight shooter. Ivan’s still the man!

You're a great example of standing by your professionalism. We all learned by this and I thank you!

Always enjoy your trip videos! Not only that but you're a good egg to stand by your work!

That is so great that you guarantee your work even during road trips! The world needs more honest and thorough mechanics like you.

Its great when a professional is honest enough to show the bad side of the job and be a real man to do it.Great video and info.

So cool man, love the road trip! A true Mobile mechanic, with honesty and integrity! That guarantee is what it’s all about. We are here to help people not take their money! As always this great content is much appreciated, thanks Ivan!

Almost no one in this industry has and stand's by such a guarantee. My pops used to say that sometimes its better to be paid in experience .

A rare occurrence for you Ivan but still, this is the sort of thing that actually makes a person a better diagnostician. Great job as usual and I'd bet that most of us would have called the high pressure pump too.

This is 💯 why you’re one of the best on YT, not afraid to show your mistakes. We’re all only human 👏🏻👏🏻

What amazes me is your reading comprehension and your ability to take on things you haven’t seen before. Figure out how they are supposed to work and then devise a fix. I think with your diagnostic ability you could excel in absolutely any technical discipline. I can barely jumpstart a car but love watching you solve problems.

It happens to the best of us brother.i have lived by the old adage you learn something new every day and some of this shit is deep.your the man,one of the best I have followed.keep up the good work

wow, this was an amazing diagnosis video, I would have concluded also with a bad high pressure pump...I guess I learned something new tonight. Thank you for the video , Ivan!

I respect you for posting this video it shows the character of a great gentleman

Wow!!!...serendipity!!..awesome video Ivan 👍😎

Very impressive! This was a case of more than one thing that was true at the same time. The obvious fuel pump issue and then the stretched chain which was hidden. Nice job!

Great video Ivan, We all make the wrong call once in a while especially being away from home and having time against us. As always your honesty shows the type of person you are, Keep up the good videos I look forward to the next one 😀

Thank you for bringing us along on this diag, all the way through to resolution. The owner "should" be very grateful because without your skills I have to bet the parts cannon would have been unloaded. You are a stand up guy!

I was surprised that you didn't check to see if timing was the issue, but seeing that you were mobile I can understand why you didn't. That's why I have the utmost respect for mobile mechanics. Time or lack there of, can be our worst enemy when trying to narrow down a quirky issue. Great vid, Ivan!

I'm originally from the Baltimore area and recognized some of the area from your video. I have lived in TX for many years and so it was good to see the old town. I thought as you were making this that to put too much into a 'road trip' can create a bug-a-boo in terms of quality due to the pressure created by such. Mobile sounds like a great idea until you consider that condition. It occurred to me that you may be cutting corners to make the timing work out, which as we saw here, sometimes doesn't work out well. And that is especially true when you encounter a really tricky one like this. All in all, you're experience coupled with your analytics make you a quality mechanic. Having spend years doing troubleshooting on control systems in another field, I can appreciate the way the system can and does trick a mechanic. I've had to, more than once, make some phone calls to get help. It happens. It can leave you feeling a bit inadequate until you realize all the good you do.

That is why if I suspect any fuel issue, I always put a little curb cleaner in the intake to see if it will start then stalls. That saves me a lot of pain

Impressed by your honesty, this is what social media is lacking, a little bit of real life!!

Very good job, you KNEW what needed to be done and ALMOST pulled the trigger!

Nothing abnormal man! Its the way it goes sometimes for one reason or the other. But the reibusement is the shining part of that video man !👋👍

All of the signs pointed to fuel starvation. 🤔 I kept thinking air lock or the high pressure side needed bleeding, 999 times out of 1000 this would have been the problem. A timing chain jumping sprockets is very very rare and the last thing you would blame. Great stuff Ivan.👍👍👍

Learned a lot, great Job Ivan !!

Good job posting the mistakes as well as the successes! Very admirable! Especially when it sucks so much to have to eat the cost of the pump and all that time you put into it too.

Another great video Ivan. Not easy when you're at the job site. If it was in the shop, I'm sure you would have nailed it.

Very cool and informative Ivan! Respect for posting the video anyways. This will of course just make your diag skills even stronger!

Appreciate your honesty. My brother tells the story of when they had an old Honda that bent a valve after a broken timing belt. They were so disgusted they just floored the engine. It didn’t blow up. In fact, it started idling smooth. I’m not sure how much Olympia was involved. Remember that beer brand? It’s an old story. But he says it’s “true”.

The early 3.5 ecoboost engines had one chain pulling all of the cams and stretching is an issue with these engines. The later models have 2 chains, one for each cylinder head. It's good to hear that the ecoboost engines are lasting that long especially 1st year engines.

A Time constraint is a very difficult issue to overcome. Thanks for bringing us along.

I love the road trips!

Awesome logical diagnosis. The thing I take from your story is that without time and the correct equipment, you are sometimes going to make mistakes.

Awesome video! Like others have said you didn’t need to post it up with an unfortunate misdiagnoses at first. You still have this logical way to talk yourself and others through what you are doing and how. Thank you for your service Ivan! One thing though did the bloke buy a lotto ticket after winding the engine backwards making it skip teeth then have the balls to try and start it after said event 😮 1 in a million chance hahaha 😂

Good channel !!!!!! I enjoy hearing you talk out loud as you are diagnosing the problem. It helps "backyard mechanics" (like me) understand what is going on !!!!! Like !!!!!

First class video , and loved the follow up , very impressed , every day is a school day for Me!

Ivan, thanks for a great video ...as always. On the subject of the GDI HP pump, the fuel quantity valve. I was looking into how the fuel quantity valve work on my engine too, Mercedes M276 3.0 Turbo. Bosch HP pump. So I want to share with you what I learn on this : This HP pump TDC or pumping event is equal to the number of fuel lobe/s of the camshaft. Some camshaft has 1, 2 , 3 or 4 fuel lobes. My engine uses 4 fuel lobes and the cam is on its Bank1. My HP pump is a normally open version for the fuel quantity valve, that means if the fuel quantity valve is not energized, pressure can not build up and it will allow the 5 BAR fuel pressure from the tank's LP fuel pump and limp home mode is using this method. Normally open type is safer too. The piston or plunger on this kind of single piston HP pump, make pressure by activation (closing) the fuel quantity valve during the upstroke of the piston. The downstroke of the piston is to let fuel into the "pumping chamber", no need to energize the fuel quantity valve as it is a normally open version. So for my 4 fuel lobes camshaft, 1 camshaft revolution there will be 4 pumping action BDC to TDC of the piston and is 45 degrees and TDC to BDC is another 45 degrees. 4 fuel lobes is 360/4 = 90 degrees. In the each 90 degrees, only 45 degrees make higher pressure, more than 45 degrees is to reduce* pressure by limiting fuel entry or quantity into chamber ( *if activated beyond 45 degrees) So this kind of HP pump, we can not simply energize 100% of the time its fuel quantity valve hoping it will deliver maximum quantity/pressure. The part I am still "blind" is, I do not know the exact location of each 4 of the TDC in respect to the camshaft 360 degrees. I have to physically inspect the cam itself to learn of these TDC... too much work, no thanks. Initially I thought using a picoscope I can find these 4 TDCs, I can yes but not with 5 degrees accuracy, perhaps only 15-20 degrees. You see the ECM activation using PWM for the fuel quantity valve is variable depending on engine RPM and load. At idle I can see 33 degrees worth of fuel quantity activation per TDC, so there are 4 of this PWM pulses sent by the ECM. I would assume the start PWM signal would be at TDC dead on, well it does not seems that way by the time I scope more and while revving up the engine. LOL. According to Audi tech at OPUS IVS channel, fuel quantity valve failure or not being "accurate" is also a common problem, aside from worn out/broken piston. I think not being accurate means the activation of the magnetic coil vs the actual reaction-to-execution time of the mechanical portion responding to the PWM signal is way off the target.

Love the honesty man. Being in the trade I'm sure u know burn to learn

Great video Ivan..

You're an honest and honourable man Ivan.

Another great case study, Ivan!! You don’t win them all, but the original diagnosis was an educated hypothesis based on a failure prone part with a large amount of miles and suspect scope data. I know, I would have made the same call. Thanks for the follow up!

Your still the man Ivan ! 👍👍👍

Hey Ivan, I loved this one. It just proves you are human and not some kind of diagnostic android from outer space who makes the correct call every time. It also makes me feel a little easier about all my bad calls :-)

It's always better to put check mark on what comes to your mind, as i see you suspect the issue but you leave because you believe in the DTC. But it's always a lesson, and that's refund is the fee for that lesson Great job as usual man Waiting for the next one 💪

Timing codes only set when the engine is running, damn. Good lessons in this one Ivan. Thanks!

I’m impressed with your honesty and that you refunded the guy, your honesty will pay off in the end with customers trusting you 👍😀

Thank you Ivan. Great video

Definitely that means you are very honest man I’m a mechanic & not mechanic is perfect, but definitely you the man bro

Very nice tour, blessings

Great video!

i learn from the two best ivan and eric o you guys are amazing i am learning to be a mechanic

Thanks for the video and the update. I was thinking that you do not want to directly connect the HP pump to 12 volts, it would draw about 40 amps. I also thought that maybe an injector failed open and caused the pressure to drop. It takes a big man to admit he doesn't know something!

Wow I admire you more, what a character. I have that same problem working on as I speak. Same symptoms on a 2012 bmw M V8 twin turbo. I don't have a pressure transducer as yet and was convinced it was the pumps although having a gut feeling it's the timing ,I took a break and thought about it. It has two high pressure pumps would both go at the same time, they could but highly unlikely, I'm still in the process of proving it's the timing.

Love you video, your a top gun and a very honest person 👌

shit happens mate. i had the feeling when the engine wanted to start and didn't i wasn't so sure it was the high pressure pump the problem. any way thanx for sharing i always watch your videos. i i do appreciate your honesty in this diagnosis you don't see much of that any more specially on video. keep up the good work!

You win some you loose some Ivan. We all human beings. Appreciate the video.

Ivan! I feel a relative compression test would have aided you fast here in confirming your timing suspicions. Then after seeing an anomaly you would have more evidence pointing to get the in cylinder transducers out and syncing timing etc, that would of helped you out way better with that variable of calling the pump. I’ve been caught out with a couple of jobs like this before and on all crank no starts now, my first port of call in all these situations is disable ignition or fuel and do a relative compression test first before I do anything else to try and get faster direction regardless of the fuel OBD codes that are present as they can lead you down a rabbit hole. That pico 600+amp clamp round the battery is the life saver when trying to see the engine mechanical condition. Great vid mate and good see you showing total honesty and honouring your customer policy. Keep up the great work, These videos are excellent. Everyone can learn from these including the customers. All the best Wayne Scope3

Thanks for sharing. Based on the engine sound, I would have checked RC along with pulse sensor on the intake and exhaust. I made the comment right at the moment I heard the engine I did not know yet at that point the conclusion, those hpp are time to the timing activation of the cam lobe and electrical signal to the flow control valve .

I work at a recycling plant with metals like aluminum and stuff like that and there is a abundance of those high-pressure fuel pumps coming back from Warranties on not just Imports including Domestics they're not dependable. And failing in an alarming way!! 10 to 15 I see a week!! All the best from Surrey BC Canada

People on the east coast are lucky to have you available for diagnostics.

Your insight is amazing, I would have never thought timing. But I do not work on Fords. I just try to keep my own older junk running. So it turns out the crank jumped out of time, time for the new owner to address that issue. Personally, I am not a fan of VVT systems, repairs can get expensive real fast.

Your a honest man brother we more like you cheers

Timing chain problems with a lot of miles. Probably why it went to salvage/auction. You're an honest person.

I am having similar issue with my Q7 glad i found your video here...I have a fuel rail pressure sensor (G247) that needs checking as i think its intermittent due to the battery being deficiently low possibly because the vehicle begun shutting down lot of components as well modules...I have iCarsoft OBDII reader as well Ross-Tech software

YOU ARE SO HONEST

Thanks for the video. Going to do my first eco-boost diagnosis. He has a cam sensor code. Not sure of the mileage yet. He replaced all cam sensors and it ran fine for a couple days, now dead again. Wish me luck.

I worked on a car that had a very intermittent crank-no-start issue with no codes. Once I caught it, I noticed that there was not enough fuel pressure. In the end, when the issue got worse, I could pinpoint it to the exhaust camshaft phasor. Apparently incorrect timing can prevent these types of high pressure fuel pumps to build pressure. I wonder if the pulses that control the pump are synchronized to the position of the camshaft?

Hey, you can’t win them all! You are a stand up guy and this video shows that! I was hoping while I watched that you would check the timing. Those Ecoboost engines are very particular about their timing and I hear lots of problems when they’re not in time. Thanks for sharing this!

Nice Job And Sometimes Goes Like That Refound And Life Continue

Wow, good ethics man. All Respect.

Good video and terrific ethics! Was the basic engine function impacted by the timing and then fuel pressure loss a consequence of not starting?

The journey won't have helped. Traffic Frazzles my brain now. I wish I lived somewhere peaceful, your house looks perfect for those of us that like to think 😁

many have learned a lesson here with you Ivan fallow your intuitions. chock it up to road lag ,

Hey next time you suspect a timing issue use starting fluid (ether)! If it’s a fuel problem the engine will start and run for a short time if it’s a timing problem it won’t run. This is also a quick test to determine if the ignition system is functioning! It’s just an old-school way of quickly diagnosing an engine problem! A real time saver to help you pinpoint where you need to start looking!😸

The carbon buildup on the bottom of the high-pressure pump seems to hint at a lack of oil changes in this truck. Since it has number stickers on the fender, I assume this was a fleet truck, which explains why they kept driving it until it wouldn't go anymore. With proper maintenance, it could still be running like a top. Interestingly, I learned that new engine oils rated with API service specification SN Plus and SP were developed with these Ecoboost engines as the test units. Apparently, it was discovered that the older oils were contributing to abrasive wear of the timing chain rollers because the carbon bits in the oil were wearing them like sandpaper. The new oils are said to keep the abrasive bits under control.

That customer is a very lucky mechanic. Not many will ever put an engine back in time by just turning the crankshaft backwards.

I would have charged extra to have someone watch over my shoulder. 😂 I don’t know how you do it, Ivan.

You did good I'd fall in the same pit hole and would never suspect timing

I applaud you for owning up to a misdiagnosis. And I know first hand how bad I 695 is around Baltimore. It's not pleasant, especially in a big truck.

Well Ivan sometime you win some ,sometimes you lose some, that’s how it goes . But you should finish your dairy of timing issue before you make that call . But you still a great mechanic 👍👍👍 by the way ! I would love to see more footage every day ?

Great video Ivan win some lose some.

Thanks Ivan for another interesting video. With reference to the high pressure fuel pump viability; would disabling the GDI fuel injectors before cranking allow the HP fuel pump pressure to rise and hold its maximum level (assuming injectors are good/no leak down)? Could this be used as a diag process without breaking something? Please advise. Thanks

Very very good job . Better luck next time .

Us techs have all been there, Ivan. Sometimes I'm happy I have finally retired at 72.

Its been my experience that most GDI engines can start and run (not well) on low side supply pressure. Also depending on design NO or NC solenoid if you unplug it, it will force full pressure. If the pressure gets to high there is a safety blow off valve that sounds like a high pitch squeel

Like you said, weird! You should have gone with your instinct, that has proven to be very reliable but, I guess, the fuel smell pulled you off to a worn out pump (which might still be worn out and leaky). Costly replacement of chains / tensioners ahead. In any case, good call on this, Ivan! Pleasant video to watch, while scratching the head, looking for the culprit 🙂

Thanks for showing that no one can get them all right all the time.

Nice work Ivan as always, stand up guy. That ThinkCar scanner looks so much like my Launch, but an upgrade it looks like, how do you like it?

Good job, integrity is rare

What a great guy to refund his money and learn from this experience. Very interesting to me how you diagnose these things. Wish I had your skills.

The primary timing chain is probably stretched out more than a couple links like they do as early as 100k miles so the timing of the fuel pump isn't in step with the position of the rotating assembly

The ford V6 are known for broken cam phasers, I saw one where it was broken in the back and the front look ok!

good man for giving him the refund and owning up to a mistake! youd be surprise how many people make up stories and lies about how something they cleared fucked up and try to make it not their fault. we all make mistakes and honestly i think any of us would of called that HPFP with 220k on it!

A couple of things jump out at me Ivan. I've had a couple of bad GDI pumps, not Fords, and the vehicle would usually run, idle only with low power, on just the low pressure pump. Secondly, not sure how you are equating the mechanical timing issue with the low pressure fault. The GDI pump is not timed and as long as the cam is actually spinning, it should be creating enough pressure if the pump is good. That pump may have indeed been failing.

So the bear nipped You a bit and You learned and made it right. It’s all part of the process but unlike most You took care of the situation. Your a good Man Ivan!

I am glad I don't own one of those. Great video!

I'm sure you would have figured it out if you had sufficient time, Ivan. You solved much more sophisticated issues than this one.

if you ever plan another trip to fla i will set up several for you in southeast alabama one is a F150 keeps running after turned off and key in the house you can unplug abs and goes dead and i probably cccould round up several more and provide a shelter to work under

Thank you!
