[@stuckinthe60s69]

Watching your videos has given me a new appreciation for you guys being called technicians rather than mechanics. I grew up working on cars that had absdolutely nothing "electronic". For engines, points and condensers, plugs, distributor caps, rotors and wires where the usual culprits, other than carb issues and the occasional fuel pump, discounting compression related and charging system issues. I was an electronics tech in the US Navy for 10 years in the 70s and I definitely see the integration of electronics into today's cars. My hat's off to you folks. Having grown up near Johnstown, it's cool to see a guy from State College tackling these issues. Thanks for the videos.

[@mattbrown5511]

Yeah, but for all the younger guys of today, you can watch their heads explode by handing them a magneto. Or a dual points distributor, or a number of other mechanical based systems. I do give them credit for their understanding of the electronics, but never give the knowledge that came before. (Like how to build pyramids)

[@vpimike2646]

Great video, Ivan. You have some great troubleshooting skills. I enjoy your videos. I'm a retired auto tech after 40 years .

[@adamtrombino106]

The 43psi was the give away. That's primary pump pressure. Also, I'm willing to bet the reason the psi was slowing going up, KOEO, was fuel percolating in the rail. I may not have looked at the roller/lifter cup either had I not been burned on a Ford 1.6 turbo that had erratic f/p due to a cracked lifter cup ( on the bottom, you had to take it out to see it) . As far as throwing a cat at it, if they suspected clogging, they could've simply removed a the upstream o2 or removed the cat itself and see if there was any change. $$ thrown at it..

[@Stoney3K]

The fact that it only showed primary pump pressure and the pump clicking had me screaming "CHECK THE FILTERS!" at first, thinking the pump was cavitating due to bad fuel flow which would have caused the ticking sound.

[@jtjones4727]

I find it hard to believe that somebody changed that high pressure pump 2 or 3 different times, and no one noticed the condition of that roller. Also, that thing sounded pretty bad before you took it out. I guess it's hard to know for sure until you've been the tech in that position though. I will definitely remember this for any future direct injection diagnostics. I imagine it takes a good bit of force to drive that high pressure pump, considering the high pressures needed in the rail to overcome the cylinder pressures. I think if i were going to engineer a direct injection system, I think I'd use some type of dual lobe setup to help spread the pressure out over a wider area, make it a little easier on the pump and camshaft lobe that has to drive it.

[@chrisc2813]

called it at the beginning,had a mechanic actually leave that out doing head on a 2.4 and couldn't figure out why it had low pressure at rail code.

[@wallebo]

[@TheOnespeedbiker]

"Something is wrong here". 👍 In 2011 2.4 Ecotec engine went to low tension oil rings that caused them to burn excessive oil. Supposedly they addressed the issue with 2013± engines but failure to change the oil every 5000 miles pretty much guarantees the oil rings will seize resulting in excessive oil loss, even though the oil level tends to remain constant due to oil dilution.

[@wallebo]

Very good tip!

[@OtherDalfite]

dealing with this very thing on my 2010. such a nightmare of a vehicle to own. should have done my research before letting the girlfriend decide to get it. lesson learned!

[@jimmykulik3438]

After 2013 they did use different rings, higher tension, but people don't take care of them. Even the 3000 mile oil change intervals are too long! When the oil monitor says 20% left you change it! Mobile one synthetic dextos additive. You never let the level drop not even a bit! I have seen 2015 2.4 l with over 200,000 miles and they were fine no timing chain changed. But if you live were it's really cold you need to vented oil filler cap incase the PVC system freezes and blows the rear main engine seal!

[@Sandmansa]

I had an 18 Ford Escape a few months ago, similar issue. They didn't change to oil in a very long time. Wound up eating a hole right through the high pressure fuel pump tappet. I replaced the pump and the tappet and it did run a whole lot better. Unfortunately, the cam was badly damaged and the engine was burning through a lot of oil. Oil level had dropped 1 quart in about an hour of it running and wasn't leaking a drop. I had no other option then to just replace the engine.

[@PineHollowAutoDiagnostics]

[@ahrenreinhardt705]

I just had a low pressure code come up last night right after firing my 2014 up after changing the oil. Cranked for ever and ran like crap with reduced engine power message but also a service stabilitrak message. P0092 and P00C6. Shut it down and restarted and it’s fine. Cleared the codes and none since. I’ve got 205,00 miles on it but it runs like a clock. Oil change every 5K since I bought it at 69,000 miles. Other than the intake gasket, coolant tank and VVT solenoids, she’s been perfect. Shifts can be a bit “crisp” here and there but at 205k, she could blow up tomorrow and it still would have been a good car for as many miles as I got out of it. Even the front end is still tight and not worn out. Never thought I’d see this much good service from an ecotec 2.4 but here we are.

[@grandsea2]

[@tomvleeuwen]

One trick that you can do to test the high pressure fuel sensor is to just test it on the low range, e.g. let all the pressure out and then see if it follows the low pressure. It won't give you a measurement on the actual working area but at least you know it is correct in the 0 to 5 bar region.

[@secretsquirrel9722]

Brilliant as always! Can I ask from a business standpoint, how does it work when you got to the point of telling them they needed to swap back to a genuine hp pump? That would not be cheap. Doubt they would be able to return the aftermarket one too. And although an educated one. You were technically firing the parts cannon without definitive proof. Ultimately, it was no high pressure being produced but it wasn't the aftermarket pump/pressure sensor at fault. How do you approach the shop on that, back when you were suggesting replacing it? Yes they missed the initial and actual cause. But the part the fitted wasn't faulty either. Now they're wearing the cost of a 2nd pump that wasn't required off your recommendation. Not criticism, genuinely trying to learn how you deal with these situations.

[@PineHollowAutoDiagnostics]

Yup valid question.There is always a balance. At times when aftermarket critical components are installed, it's cheaper to install the OEM than to pay for more diag time to 100% condemn the aftermarket part. Once that is ruled out, then makes my job easier :)

Yikes.. I'm surprised it wasn't making more noise. I still wish I knew how the high pressure regulator works on these, and whether it's built into the pump or not. I think I'm going to look up a few direct injection diag videos, and see how it all works. It still has a few mysteries for me.

[@mattbrown5511]

I'll be joining you. I already know to steer clear of CVT transmissions.

[@ferrumignis]

They are fairly simple, at least conceptually. It's a reciprocating (piston) type pump and the inlet valve is solenoid controlled. The valve opening is synchronised to the cam position. Pressure control works somewhat like the intake valve in an Atkinson cycle engine, to reduce pump flow (and therefore pressure for a given demand) the inlet valve is closed later, allowing some of the fuel in the cylinder to be returned back to the fuel supply rather than being compressed and pushed into the fuel rail. The later the valve is closed, the lower the fuel flow.

[@dharley189]

@@ferrumignisif the solenoid or circuit fails does the pressure go excessive or possibly hydro lock ? Thanks for the explanation. I’m retired after 45 yr career. GDI was still new when I retired so it’s a new system for me.

Had one of these similar situations, forget the model year, but the high pressure pump has a little button that fits on the pump that fell off and wouldn't allow any fuel pressure to build. Wasn't even contacting the cam.

The bashed out roller would also explain the jerky cam phasing, since there would be particles of that roller all over the oil system, and possibly clogging up the cam phasors (unless they're completely electrical). I still remember your videos on the Ecotec control solenoid screens causing more problems than they fix. So an oil system flush may even be in order.

@@jimyep9971 job is done, says all good to go, pay them, drive car and no better than b4, like i said, mechanics in my area are crooks. either they charge 4hrs for an hours work and\or theyre part changers that give 90 day parts warranty but still ding u for their labor which they over charge in the first place. thats why i have learned to do my own work with the help of ivan and like minded youtube mechanics. i have to thank the shitty mechanics that ive gone to for forcing me me to learn and fix my own stuff

wow craptiva strikes again, tricky one Ivan, without working diagnosing these often that looks like a needle in hay stack for commoners LOL..kudos mate.

Just started the video but I'm going to guess that there is a timing problem due to oil pressure issues though I would like to see what the fuel alcohol sensor is saying as it will cause all these same symptoms if it does the error and gets stuck with a false reading of high alcohol content and when it does it it's dumping pretty much double the amount of fuel than it needs on regular gas. Disconnect the battery or if there's a way to reset with the scan tool reset it and the problem goes away

[@richardcranium5839]

i'm surprised it ran off low pressure pump. that should have been checked.

Wow, bad roller? All the parts cannon was unnecessary!! At least you found the problem! But the customer should not have suffered the high cost of ask this unnecessary fixes. Shop has to eat the cost. Idk, maybe.

[@dosgos]

Would the camshaft be trashed from the bad roller? One could see the camshaft through the hole, just move the crankshaft with a big wrench. When the original HPFP was changed, the tech should have taken a minute to inspect the roller, clean it, and bathe it in oil IMHO.

That engine reduced power must b a general motor problem. I seen it in multiple cars

[@rickycrews4172]

Even OEM fails when new unfortunately

[@maxeaves]

Ivan. That engine sounded like a bag of bolts. I'm not sure that it will be long for this world as it sounds like the bottom end is knocking...

[@freedellis6619]

HPFP runs off a cam lobe that maybe worn causing the changes in fuel psi.
