My 2007 corolla verso 2.2 Diesel will start the first time without a problem and idle normally. After about one minute or so, a warning light will show up on the dash then after another 30 seconds, the engine cuts out. When the engine dies, I can restart again without a problem and the whole scenario starts over this happen until the engine warms up. once the temperature reaches 60 and the blue light goes off the car works fine the rest of the day. I cleaned the EGR, polished the glow plugs and tested them, put a new fuel filter, tried a working SCV from my mate's car, and did a full tank with fuel treatments. None of the above-mentioned worked however the car performance is much better. I tried to warm up the fuel rail line with a hot cloth soaked in hot water and will top it with hot water every now and then and the car did not cut off but won't drive as normal unless the engine itself is warmed up. Once it is warmed up it runs fine. Any idea what else could it be? Thank you
Thank you very much for this demonstration ! I constantly clean my Injectors with the Liqui Moly Diesel Purge (see my videos) and the return flow per injector are nearly the same.
Excellent video presentation, very well explained. Trying to get a 2007 Nissan Qashqai with 1,5dci engine non-starter started, will do all these tests to determine where is the problem. Thank You Very Much. COMMENT All the way from Maputo/Mozambique
On my car , all the injectors returned same values , what amazed me is that in 5 minute the return line from the rail leaked 1l of diesel , is that normal or what could be wrong as i believe it shouldn't be returning any diesel through that line ,instead flow the diesel from the injectors back into tank . Any suggestion?
We had the problem the engine feld out if asking for power. Normal driving was 95 % no problem but as soon as we wanted to like overtaking a car fast, motor fail and out. Restart with in a second so no problem. With this test we noticed 1 injector had a full jar the others normal. To mutch diesel running back to the tank in that injector. Refurbished injector brought the solution and the car goes as it was new. But I do have a question. In the early days befor commonrail we use to do some petrol in the diesel to prevent from freezing in the winter. Now I am been told in common rail you must not do it it would arm the engine. Is this true? And more in the older type of dieselcars I use to do some simpel engine oil in the dieseltank before filling up the tank with diesel. Made 700 to 800 K in km with no ever problem. So what if I would do so in the common rail car?
happy working my friend, I want to turn on the PC300-8 engine without a monitor, he is a common rail type using PCU ECM, can you explain how and what I have to prepare
Are you trying to start komatsu pc300-8 engine out chassis. Yes it can be done.if your monitor is password protected then u need to removed the monitor from the machine.then rewire .we have almost 20unit of this model.yes is commonrail engine.

and even a big BAG from the engine while is running at moderate revs. That is what you can get as well from a back leak injectors, when sendind 3-4 times as much diesel back to the diesel tank... BMW E90 M47 2 LITRES ENGINE with 300k miles on the clock, original injectors since.. 2005. All system treated with 2 stroke oil 250ml/50 litres of diesel from 250k miles. The engine never missed a start. At present day 2 injectors were rebuild.
You can even have a really really loud BANG, like a hammer hit on a metal plate, or as you stall a diesel engine when you try to start driving. It happend to me while I was driving at about 30-40 miles/h, about 2000rpm.. It was nasty and scarry bang. I found out that 2 injectors were leaking almost 3 times as much fuel as the other 2... after 300k miles on the clock with these injectors. I dismatle the tip, spray .. brake cleaner, all 6 holes clear of build up.. Try to understand what practicall happen to get that BIG BANG to almost stall.. The car was still running, the engine didn't stop or anything...
Waaaaaw tank U very much. I have Toyota hiac 2016 model on the morning it was starting but shcking for one minute bad noise. After some minutes it becomes normal. Please waht can you gesse.
An excellent demo about the excess fuel returm. Do you have any idea why my diesel engine oil level raises? It's not the coollant, but diasel fuel got into the engine oil. Are the injectors to blame? Thanks!
Or sticky injector, nozzel pin staying open - but you would have noticeable economy / driveability symptoms. ALSO depending on the the type of diesel engine - if its a passanger type diesel after 2007 fitted with a DPF and unlike commercial diesel. This DPF does not have an seperate injector for the DPF- it will just send extra fuel into the cylinders to reach the DPF in the exhaust stroke. Have a look into it if you are unsure.
Very helpful and brilliantly explained
Very good video. You spend alot of time for this demonstration. Thanks
Thank you for sharing this information. Very helpful

I would suggest you take your vehicle to your nearest dealer for further diagnosis
Excellent demonstration

Did you find a solution???
Maybe you have error codes,
You can do an obd test with an error codes reader
Do you know what could be the minimum allowable amount of returned diesel in ml? Thanks for useful video
i think that is manufacturer specific. on my bmw the new injectors are 1-2ccm/min and if it is greater than 10ccm/min then it is a bad injector
I have a 2013 deseal engine crank no start i found out that there is no power on the egector it it right or wring

Sir thier is an engine oil passing thrue into common rail pressure pump?
Can a bad fuel pressure sensor caused an injector to leak?
Great job!
Thanks Teacher
Great video!!
Good massage
Unconnect supply pipe from ramp end install plug in rapm, start motor and watch on supply pipe. If you see some drops from it -injector leacking.
How can dealing with back leaking please help me

@@vsheavy2792 ok thanks the information is very helpful
very good master
Thankyou sir
Very well demonstrated. Where does the Leaked Off Fuel normally go to, and is it pumped to it's destination?
Fuel tank
on case of my om648 it goes back to be filtered again to the fuel filter! and back again!
🎉very good
good
Thank
Bravoo
Excellent demonstration and explanation, thank you so much...
The best l have seen the way you discribe
how the systems work
is very understanding
and a bonus to the people you teach .
Every day is a school day! Solid instruction. 👌 Great production.

Thanks you very, I need more lessons on Desiel electronics, how can I join
As an automotive trainer myself, I like your set up with the board behind with pre-done connectors.
Or 3 injectors could be bad and 1 good
Did we know how much=ml is the flow of return diesel from injectors???
You don't show that crankshaft sensor is with 2-wires
And camshaft sensor is with 3-wires
Thank you sir, thank you so much for your clearyfeecation
If the injectors leak to the bottle full the engine will start ono
Very good demonstration. Better than a lot of manufacturers courses I've been sent on.
Thank u so much. I benefited and acquired some knowledge from your outstanding training.. by the way where does your college locate ?
Hi Mohamed, we are located in Mount Edgecombe Durban

Thought of asking possible reason when one injector back leak is less compared with others
What if you had diesel coming through the return line for the injectors , how would you diagnose that problem, help anyone ,plz
Hahaha, the apprentice looks like a cardboard cutout in the first part of the video, great video by the way
Thank you for the information sir ,
How i can translation english to Indian language .
Am so grateful for your education
Please how can I get your contact
And also need the diagnostic machine so please how can I get it please?
Beutiful explaination on common rail system..
So cant do return test on duramax. By look of it
I am honoured to be one of your students Sir
Thank you so much sir. It was so sweet
were is my freind "deClerk"
This is not a pwm signal
Excellent demonstration
Very helpful
thank you sir.
Excellent work..

Fantastic.
excellent

My skoda Octavia not returning fuel form return value
Whats tha reson
From the return valve of one injector? If so then that injector is most likely bad.
An excellent demo about the excess fuel returm.
Do you have any idea why my diesel engine oil level raises? It's not the coollant, but diasel fuel got into the engine oil. Are the injectors to blame? Thanks!
Leak on return line or pump!
Or sticky injector, nozzel pin staying open - but you would have noticeable economy / driveability symptoms. ALSO depending on the the type of diesel engine - if its a passanger type diesel after 2007 fitted with a DPF and unlike commercial diesel. This DPF does not have an seperate injector for the DPF- it will just send extra fuel into the cylinders to reach the DPF in the exhaust stroke. Have a look into it if you are unsure.
🙋♂️😀👍🙏
Thanks best videos ever see
Hey mate
what if fuel leaks out of the fuel flow, can it be fixed or retightened to stop leak
thanks
Where does it leak?
