- Today we talk fuel injectors! As part of my rebuild project I had the fuel rail and injectors out so I decided to uninstall them and clean them before reinstall. Below you will find a link to the cleaner I used and be sure to drop any questions you have in the comments below. Thanks for watching!

Good guide. But remember that if you got a newer car you need to place the injectors where you removed them or reprogram the cars computer.
Yes be careful not to mix them up.
Wild, Didn’t even know that was a thing. Great tip! I will pin this comment.
Yes good idea to number them, I am ocd about that everything is numbered, firing order and distributor map/rotation etc drawn under the hood for quick reference - some bolt torques too
Excellent video
I dont believe that because what happens when you need to replace one do they make a specific spare now you can't change with different types only because they have different connections please tell me which vehicle needs reprogramming for new or moved around injectors
I remember cleaning mechanical injectors on my old Mercedes. Always did it with diesel, or at least the final rinse. Good cleaning agent, lubrication and no fire hazard while testing spray patterns.
Glad to see a new video. Cool seeing you in CO!
Hey Clayton!
It was awesome meeting you! Thanks for reaching out. 💪🏻 this video was pre-recorded but I plan to give you a shoutout on my next video 😄
Have a great weekend.
Stumbled on your channel, like the way you present things, subbed!.
Thanks for the sub Santiago!
Bro thanks for the video. Had a bad feeling about this shop talking about replacing basically my whole fuel system as they knew I didn’t know much about cars. But saw your method and thought wouldn’t hurt trying it out before spending the 800 bucks they quoted me. Needless to say my car is running and feeling like it’s new again. I had an engine light on after doing this cleaning code is gone hasn’t came back and you literally saved me 800 dollars. Thanks much my guy
That's so awesome to hear and it's stuff like this that makes me love making these videos. Thanks for sharing!
What symptoms did you have before you tried it?
Love hearing things like this i thankful for people that make videos and share knowledge
Thanks for providing the principle of fuel injector cleaning, in the past I replaced all for new ones
No problem 👍
Also good to try and spray the cleaner before pulsing to check if you have a leaking injector, nothing should spray or drip without power being added. Thanks for the video.
Thanks car dude! Excellent! Thanks for sharing our knowledge
Thank you sir, great video and explanation
Glad you liked it! Thanks for watching,
Nice Video and Helpful 👍
Glad it was helpful! Thanks for watching.
This will help me save on buying new fuel injectors for my 89 miata mx5 new ones are spendy an the fuel. Injector tester or cleaner on Amazon is cheap 25 something not bad man thank u on the heads up on finding a tester or cleaner tool. Gonna buy me one to clean out my injectors and gonna buy new rubber rings for the injectors as well this will help an save me money n time from buying new ones thanks again man glad I TH-camd this. Have a blessing days a head of u man an be sage working on other people's car's 🙏
Thank you for your excellent explanation!
You are welcome!
Thanks for making this👍🏻
You're welcome. ☺️
Well explained, has going to be doing mine, been looking through various sites, clarity 10 out of 10,
👍🏻👍🏻
That was interesting. Had not seen that procedure before.
Never tried it before. Seems to have done the trick.
I remember I did this, and the pressure made the Injector flew out of the tube and Carb Cleaner sprayed right in my right eye 😂😂😂 I stumbled my way to the faucet. And my eye was red and slightly blurred for the next few days 😂😂😂
Want to try this on my 2000 GMC Sierra. It’s got over 300k on the dash with original injectors
Wow 300k that's amazing I love it 😁👍🏾
You should! I might help out power if they are a little clogged over time.
Don’t those trucks have the injector spider setup that lives inside the intake ? I don’t think you will clean those ones up so simply it involves removing the upper intake, annoying fuel line connection nuts are buried behind the firewall. Those ones I wouldn’t try to clean just buy a new spider and a seal kit as they are upgraded design kits.
Thanks for the tip
No problem!
very helpful video
Thanks man!
I was wonder if You could help me. I a 1995 Oldsmobile 88 and was testing the fuel pressure regulater and I drained some fuel into a bottle and there is oil in the fuel. What does that mean?
If you remove a new o-ring before cleaning (for some reason even a new o-ring gets slightly torn during cleaning by that white plastic connector, which sprays, so I use a separate o-ring for cleaning, then remove it and put back the original new one) can you put it back? Or once removed the o-ring should be replaced even if it is new? Thank you for a great film.
Your question seems a little self contradictory, but I would use the old o-ring for cleaning the same as CG did and then replace it with the new one.
@@CycloneCyd Yes, I'm sorry, just thought about 2 procedures and described one. See besides that cleaning I also replaced the o-rings on the bottom of course, but they were wrong ones (too thick, I couldn't install w/them into the Intake Manifold. So I removed them and put thinner ones fm/another set. I'll use those removed for cleaning, and asked out of curiosity, could I possibly reuse them. Also could be you installed the o-rings and then decided to clean them, so you remove those new o-rings, clean the injectors and put back those removed. Also there are methods to clean without o-rings, but rather using a clamp. Thank you for the replay.
@@olenaerhardt7725 yes you can reinstall newer ones again as long as they aren’t damaged
Good video Ray. On the injectors, if the spray tip screen is covered with varnish, brown or even black, should it be cleaned or get new ones? They work fine and spray good, but look like crap.
Did you try soaking a q-tip in cleaner and rubbing the tip? That should clean it up. If that doesn't work you could probably soak them in a shallow tray. Afterward be sure to run cleaner through it to get anything that may have gotten in there out.
@@Rythecarguy don't soak injectors in a tray where they lay down. Find something the injectors can 'stand' in (like an aerosol lid or old mug), place the injectors pintle down and put in enough cleaner to cover the pintles only.
If you soak injectors laying down so the cleaner gets inside, it can damage them (in particular dissolve the coating on the copper wire of the coil causing a short).
@@CycloneCyd thanks, yet what is a pintle? Sorry, I m Dutch, don't know the word
@@TheMrBennito The pintle is the spray end.
@@CycloneCyd figured so, thanks! I had checked out yr vid first before I got here, straightforward stuff!
Is it true for 2006 infiniti vehicle that injectors are specific to their spot on the rail?
good job
Thanks!
My car is Nissan Xterra 2008, but I cannot open the valve that connects the tube and the injectors. I apologize for my language. I am from Iraq. Please help, thank you.
Those look suspiciously like Denso injectors. Don't they have a microfilter at the top? Nor any plastic o-ring retainers?
No I didn't see either
Can you apply 3M Silicon Paste (Dielectric Grease) on o-rings instead of car oil or always oil?
Yes, that's what I showed in my video on injector rebuild. Just a smear mind.
@@CycloneCyd O'K. Thank you.
👍🏻
No inlet filters?
Have u seen a difference in gas mileage? Ive run many fuel injector cleaners the years but ive never taken it apart. My Frontier runs great other than terrible mpgs
I'm sorry but I don't know. I have never tracked it,
Quick question. Would it be a good idea to replace the dampener since you have the rail out already?
You can if you want to knock it out for maintenance sake but it's usually a simple diaphragm that lasts as long as the car.
@@Rythecarguy Thank you for your vids. I plan on tackling this job but I plan on replacing all new plugs, injectors and coilpacks. For peace of mind
If I recently changed my O rings like a few months ago can I reuse them or do these become bad as soon as you pull them out?
Eh. I would send it, you should be fine. Just check for leaks when you first start it back up
I saw a guy putting some automatic transmission fluid inside the injectors after cleaning them 😳 i just wonder why?
I've often wondered about clogged and or dirty injectors, I'm still driving my 2000 F250 V10 and have NEVER done this. she runs like a top. and yea. I run Walmart fuel!
I would think this would be something you would do only if you're experiencing symptoms
Which preserving agent do you use for long storage time?
Sta-bil all day.
The retaining clip on the 2004 mustang is AWFUL. I have no idea how to get it off without breaking it....
Im sorry, jump on amazon and get yourself a new set. You are technically not supposed to reuse them anyway.
What about a back flush? Thinking about doing this
For coolant?
good
Thank
Thx
Yw
I hope you have a fire extinguisher handy , carb cleaner is quite flammable , and you have a battery and open wiring all on the bench there , just a spark , and , poof !
Yea, I should really get one of those, started welding recently too.
Do this job outside I'd say. That way cleaner fumes blow away too
@@pobinr way less fun that way though 🤪
Hey Ry, I have an 07 nissan frontier and have the factory fuel injectors but my lower oring is shaped like a circular square. But when I go to name brand auto stores they have the circular round ones like the ones in this video. Have you seen this before?
Is it just deformed from being pressed into the manifold? What is the shape of the hole it goes in?
What about changing out the filters?
Only tackle that if cleaning them does not help the spray pattern.
What about seam foam cleaner with an ultra sound cleaner device? Does it work as well? Have anybody tried it to clean injectors?
That sounds like a good plan. I don't have any experience with it however.
@@Rythecarguy Thanks for the feedback. :")
What would cause the injector to stay slightly open after the car is off, leaking into the cylinder, causing a sluggish/rich start if tried to restart after sitting 10 mins. The gaa will evaporate over night and starts fine. Do you feel the injector is fixable/cleanable?
There's a spring loaded seating valve in injector and an above solenoid that lifts it off the seat per pulse, spring can go bad are like a engine valve the seat can wear and cause the leak down,, replace the injector but keep an eye on engine oil for gas smell in dip stick,, a leaking injector can destroy an engine
@@elgastsos210 how do you know injector is slightly open,, only way is to have it out too see the leak at bottom, what the needle in fuel pressure gauge it should jumping insyinc with injector pulses,
@@georgespangler1517 yup, I’ve seen carbs do that too and mech fuel pumps
👍
is there a difference in the fuel consumption?
I'm sorry but I never checked any of that.
That is such a cool little fuel injector tester. The issue I have is the spray can I have does not hold pressure. It leaks where the straw and the push nozzle join so I have to buy a different can.
You can put some heat shrink tubing between them and heat to form a seal
Where I can get the o ring for injectors? Thanks
Auto parts store
I would go with OEM from the dealer.
I did my injectors on my Xterra but left the fuel rail on the engine. I lost one of my blue o-rings for a few minutes and started freaking out.
Oh yea. I would have freaked. Sounds like you worked it out. 💪🏻
i did this and didn't know i had a fuel filter inlet inside the injector , it destroyed it .. did you remove yours prior to doing this or did it not come with one
No, mine must not have had any, how did you destroy the filter? There is no way you put more pressure in it than the car does.
@@Rythecarguy
i forgot to mention i did this for a 8th gen civic ...i did exactly what u did and i decided to clean the inlet hole, by surprise there were broken pieces of the inlet filter inside the injector from the force of the spray due to the inlet filter being brittle from old age, it was my fault then, shouldve check before i did it... i didn't know there was a filter on mine 😀 , should've had taken if off before i did the cleaning.
How can I clean without that cleaner tool
soak just the tips?
Use steps of various size heat shrink to adapt to the tip of the cleaner
I wish I had seen that before...but I was pretty the same except the clips 11:04
🤘🏻🤘🏻
Isn't it better to just replace the injectors?
Not if there is nothing wrong with them.
@@Rythecarguy Thanks for replying. I've got a 2007 titan 190k miles gas mileage in city has been terrible. used to get 17mpg now like 10mpg. I've replaced plugs, coils and no difference. So I thought about replacing injectors. Your thoughts.
Can you please give me the address of your place so I can go to my apartment i
😆
Personally, not very helpful for your average joe not trying to spend $1k cleaning these. I'll let the mechanic do it, too many moving parts here. Thanks for the video though.
Not sure what you mean, I spent less that $50 cleaning these. Like 35 for the machine and a couple bucks for the cleaning solution.
Just buy new one instead of wasting the time cleaning them. They going to get dirty again in like in a month
Totally, just spend over $1000 to replace totally functional injectors. Love that idea. 😆
Spray gunk in there of any kind is a huge mistake
Huh?
Why would you not just buy new injectors?
Because to get ones that are not complete garbage you're looking at at least $500. So if they're functional and all they need to do is be tidied up the why wouldn't you reuse the old ones?
