www.toxicdiesel... How To Check if You Have Bad Injectors Without Paying For a Diagnostics Fee. Do It Your Self. Weak or Bad Fuel Injectors and Solenoids
When I had a leaking injector in my semi, I discovered it by the increased level in my oil pan. I did an oil analysis, and found it was fuel causing the increase. Took the valve cover off to verify that it was an injector leaking, and which one it was. I only needed to change an o-ring, but did all six. No problems after that.
Been chasing a problem for 2 months on my 04 cummins, watched this video and found out 5 out of the 6 injectors were puking fuel out of the top just like your video showed. My symptoms didn’t match injectors but this test just summed it all up. I had no smoke at idle just ran like 💩 driving under a load. When I data logged it, it had 127.4% engine load didn’t make any sense to me nor did it have a check engine light. Hopefully this saves my truck and brings it back to life once again!
@@xmo552 yes it sounded like a heavy knock from the mid portion of the motor. I luckily had a thermal imager to see if one of the injectors got stuck open. And sure enough cylinder 3 had a stuck open injector, I had it sent out and tested and the solenoid was junk, aka a fuel knock is what mine was
@@bronsond7552 I just replaced my #3 injector today. It's better but it still does it. It knocks hard between 50-60 mph. I'm at 288k, I may have more bad injectors. I have to drive very slow to prevent the knock OR stomp on it and get past the 50-60 mph but then I overheat asap. 2 techs at 2 locations told me it was #3, but I think it makes sense that I may have more than just #3 bad. Maybe that was just the worst leaker.
Update: Head came off. Found a broken ring caused by turbo leaking oil. It's been down a month and nobody in the damn country can find parts to rebuild a stock 5.9 Cummins right now.
06 5.9 noticed when I start it’s louder faster idle. Doesn’t go away when warmed up. When you put in gear it’s rearing to go . Dumped heavy dose of hot shots extreme in fuel and their edt. Yesterday I started seemed calmed down but back again. Could anyone point me in right direction thank you
Hello I have 2006 dodge 2500 and it just started to do this, starts normal idle normal but when I start to drive it quits accelerating and then accelerate again it keeps doing it until I can get to a speed of above 30 or 40 at hi speeds doesn’t do it but if I stop at a light it starts to do it again it has new filter and new fuel pump what could be the next step
I have a 98 24v 5.9 cummins. It starts and idles fine but when you touch the accelerator it jerks violently. So bad you cant drive it unless you really ride the clutch. Also it will not go over 2000 rpms. Bogs down near 2000 rpms. What can this be. Im pretty new with diesel engines but more than willing to learn.
I have 2000 Dodge Ram 3500 5.9 Cummins it cranks up but the it hesitate then shut off after a while the code it gave me was p0216 I just change the vp44 on it but it still does the same thing.
I have a 01 and it started throwing a 1690 and 1693 I believe code and it sounds like a power stroke running or like it's cold sounding when u push on pedal driving wat could it be I can't figure it out
believe doing such a thing would increase pumps output to provide more fuel to the rail providing increased fuel. ... curious.. where you read of this procedure.?
just being realistic. 25000psi of fuel pressure....for 3-5 mins with no real load you'd leak a lil too. much safer to just ohm them like dmax injectors
BAMBAM359 that only test the electrical portion of the injector not the mechanical side. Leaking injectors usually come from over pressurization. The correct way to test the injectors is to pull them and send them out for bench testing.
Can anybody tell me what could be wrong with my truck I recently rebuild my injectors and after that I have a white smoke coming out a lot of it I did not to replace it nozzles
TKS FOR LET THE PEAPLE KNOW! i tow my 07 5.9L cummins at the dealer shop for a mecanic problem some times start fine and some times do not start,they tell me that i need to replace the full (6) injectors cuz have a fuel leak. BUT THEY DONT TELL ME WICH ONE HAS A FUEL LEAK.! thanks for help peaple.!
I'm having the same problem and I thi k it's my injectors, just don't know for sure would hate to remove them and that not be what's wrong with it. I have power and speed it just smokes alot

Did it sound like rod knock?

Your video saved my truck motor Thanks for the info.
I did it on my truck and less than 30 seconds found two bad injector thank you for your help!!!!
Thats the exact noise mine just started making today after 250 Miles on brand,new injectors
Change the solenoid and replace the 2 orings and call it a day.

I'm having to do the Same thing in my 07 5.9 and it only has roughly 170,000 miles. Wish I could be prevented this before.

So it was leaking oil into the crank case?
leaking fuel into the crankcase. If your oil level is going UP this could be why

More than likely it’s the injector pump. They’re well known to go out on the 98.5 to 2002 24 valves
I just got this issue.
seems like it would be better to replace them all ...
Couldnt you just start your truck let it idle for a bit then pull the cover off? if its leaking you would be able to see it correct?
If they're just start the mansions just firing buying save what can cause the problem pls sir
What symptoms did u have? How did you know to look for this? Thanks
I have a motorhome that needs some work done
I have 2000 Dodge Ram 3500 5.9 Cummins it cranks up but the it hesitate then shut off after a while the code it gave me was p0216 I just change the vp44 on it but it still does the same thing.
Is the customer keeping up on the oil changes 🤔
Your oil looks well past due
I have a 01 and it started throwing a 1690 and 1693 I believe code and it sounds like a power stroke running or like it's cold sounding when u push on pedal driving wat could it be I can't figure it out
What was the final diagnosis
How the hell did you do that and help a brother out how can I do that.
I have a 2002 Cummins throwing a injector timming code
Where is the fuel pessure reg sensor?
Its behind the injection pump, on the left front of the motor You'll see a pulley on the front of it since the pump is gear driven.
You'll see a pulley on the front of it?? I thought you would not see a pulley since it is gear driven.
why did you pull the return line off and monitor fuel out? that would have give same answer less deconstruction?
Alex Zippay how is that?
Why disconnect the fuel pressure regulator? I've read about this diagnostic procedure several times but no one else has mentioned this.
It maxes out the pump so you can see the leak easier
believe doing such a thing would increase pumps output to provide more fuel to the rail providing increased fuel. ... curious.. where you read of this procedure.?
What causes them to leak? 2 of mine are leaking right now on 03 5.9 HO motor.

I have a 07 cummings dont know much about them but my truck is smoking alot alot white smoke any ideas
I'm having the same problem and I thi k it's my injectors, just don't know for sure would hate to remove them and that not be what's wrong with it. I have power and speed it just smokes alot
Blue is diesel I think
And white is water
I’m gonna bet you have low compression
These fucking ads are getting ridiculous. any good ad blockers out there?
Skip to the end of the video and click replay. The ads will be gone.
We can test common rail injectors and rebuild any that do not pass 406injectors.com/products/common-rail-injector-testing
they aren't junk they are just bad. wtf. lol
Could just be the o ring inside. Pop the top off with a socket and change them out and put it back together.
