How to replace leaking fuel injector o rings on a 03-08 Corolla / Matrix / Vibe

[@josephgray3738]

Hey Sebas, great content - funny enough, I just ended up doing something similar for my 03 GT (poor idle, misfire #4, random CEL for lean bank 2)..was pretty much spot on this same issue. Sure enough, cylinder 4 injector was COVERED in oil/grit/gas (same puddle), and coil #4 was a generic JEC (Not a Denso). I got lucky and found a relatively low mileage donor car here in IL; grabbed all 4 coils and injectors. I ended up doing a (Denso) refresh kit for every coil, a valve cover gasket, new NGK's, and cleaned/swapped a junkyard injector and matched seals. I also took the time to clean up the other 3 injectors, seals, and the area where they seat. No more Misfires, idle issues, and CEL's. I might go back and use the Toyota (new) parts you supplied and replace with NEW o-rings. 03 1ZZFE Celica GT with 210K. Thanks man, your knowledge and expertise has been a lifesaver with these engines!

Thanks for the words fam. Really appreciate the feedback people leave in the comment section like this one.

What is serviceable on the coils? What's in the refresh kit?

[@josephgray3738]

@@g.bergervoet4505 I think my replies kept getting removed by YT for linking - Coils have 3 serviceable parts (Boot, Spring, Top Seal). DENSO Refresh kit has 4 bags (each coil) containing those 3 parts. Hardest part was figuring out how to get out/get in the new spring - took some tinkering, but best way I found was needle-nose pliers to twist out the old spring, same pliers to twist in the new spring. The spring should freely rotate twisting out and twisting in - the opposite way "locks" the spring to the coil and wont move. I found my kit on Rock Auto > 03 Celica GT > Ignition > Spark Plug / Coil-On-Plug Boot > Set > DENSO part 6714319 (at the bottom). Make sure you get the right kit for your car, mine is a GT, there is a different part for the GTS.

Good stuff bro. Mexicano from NY with an 04 Corolla LE so I can relate to your videos when fixing them up 👍🏽👍🏽

Thanks fam! Keep supporting the channel!

Came to watch this video as I was just quoted $2450.50 for replacement of all 4 fuel injectors (a single one was found to be faulty and causing rough idle and fuel economy loss). Seeing how easy to access it all is, I'm quite confident in changing the injectors myself and saving myself quite a bit of money lol.

[@2zzlow]

Very easy stuff, one thing I probably should of mentioned was Lubricate the o rings so they don’t rip putting them in the fuel rail. Maybe with some thin coat of oil

[@eamonnparsons3155]

@@2zzlow I have watched a few other videos and read some forum posts about the job that mentioned this, so definitely will do, cheers.

[@Commando484z]

2450 for fuel injector replacement...what in the hell .....man thats crazy

[@eamonnparsons3155]

@@Commando484z Worst part. It wasn't even the fuel injector, the rough-idle continued after I replaced the injectors. I wasn't sure what to do, found a recommended mechanic and took it to him to diagnose. Found a faulty ignition coil in about 2 minutes, fixed and replaced for $150 within 15 minutes. Some mechanics are so dodgey and charge for the most random, unnecessary work.

[@hanielbomb]

Thanks for the content.

[@2zzlow]

No problem!

[@isaacsmith5611]

Thank you for the part numbers 🙏🏼

[@g.bergervoet4505]

I assume the process on the 2zz is about the same? Just checked mine and there is a puddle of gas near one of the injectors. Thanks for reminding me yet again about random maintenance items on these engines. You are my go to channel for Toyota tutorials.

[@2zzlow]

Pretty much the same process! thanks for the kind words!

[@SeanBeyond]

So My Corolla has a rough time starting and dies immediately after idling, changed mass airflow sensor, throttle body, fuel pump and battery and the same thing happens. Started to smell gas and checked the fuel injectors and rail. Unplugged the electrical and when I plug them back down the injector leaked out the side of the insulator donut. Could this be why my 08 Corolla is stalling after turning it on ? Turns on good after 2-3 tries and runs great tcc is going bad I have a code but no stalling when coming to a stop and drives well . Only problem is starting and dying immediately

[@user83200]

Hey thanks for the video. I’m looking to do this on my 2ZZ. I see 2ZZ has different lower insulators (23291-0V020). Are the top o-rings the same between 1ZZ and 2ZZ?

[@jeo8275]

Bro make sure u change the camshaft position sensor the exact same thing happened to me i changed the fuel injectors and it was having a bad time starting up and i changed it and now is good

[@2zzlow]

ill keep that in mind, thanks!

[@craighelmrick5713]

What is the torque spec on the fuel rail? Gaskets are a little different on my 2000 vvti, I seem to squish/ruin them but if I go light they still leak

[@reddemon52]

lol the pintle caps? are they important? tip of injectors . I went to junk yard removed injectors but they did not have the caps... will it affect spray or not work properly?

[@jakemaksin3273]

I’d appreciate more content on how you did it for instance how it went taking off your fuel rail and talking about releasing the fuel pressure. Also trying to do this on my own if I just watched I feel Like I could be more comfortable with mine.

[@2zzlow]

I didn’t really release the fuel pressure since it was low to begin with but what you would want to do is remove the fuel pump fuse and run the vehicle until it dies

[@gorehammer1]

It’s stupid easy, don’t worry about depressurization. Just pop that shit off and flip the fuel rail out of the way. You will only get a few drips. Only thing to watch out for is o rings rolling and pinching when you reinstall the rail. I like to lightly oil the rings and seat the injectors in the fuel rail first to make sure they seat properly and then put the rail with the injectors into place. Don’t over torque the bolts for the fuel rail, it doesn’t need to be that tight.

[@andyg5004]

Do those fuel rail spacers go bad with time

[@anthonywiseman174]

Great content mate . Carnt wait see fuel pump replacement that's what I'm going todo Toyota celica tho .

[@2zzlow]

uploaded and its pretty much the same procedure

[@justinbuchignani4008]

Mine has 250k I need fuel injectors and a new fuel pump and filter as well. It was sitting in the weeds when I got it so pretty much going to replace the whole suspension as well and fix the exhaust issues as well as replace the rocker panels on both sides

[@ivanrousseau5066]

i watched this because i cant get my injectors to stop leaking .but the idile prob many talk about might be the intake manifold gasket ..its a prob on these engines and that fixed my stalling and idle prob but right now I need a video that show the right way to install injectors because I'm about to lose my mind trying to get theses new injectors to stop leaking.

[@firstname-qq3xp]

Im in the same boat dude. I changed the seals as well. Same problem, gas pooling.

[@CallieCEntertainment]

Go slowly, you can spray brake or carb cleaner (or dip then in a little gas) on the seals to lubricate them and then you hand seat the rail. You do not use the bolts on the rail to seat them because it will pinch the o-rings.

[@seblo8462]

The 1zz is super reliable and strong, but have noticed that at 300k, i started getting issues every month lol. 1st the valve cover gasket got a nasty leak, then the egr, then got a misfire in piston 3 with a "lean code" and replace the intake manifold gasket and ran better, then the coil went bad in cylinder 3, replaced and got better, now got a misfire again and got a feeling it might be this injector problem, hopefully lol.

[@MikeHart72]

Switch injector 3 with injector 1. If the misfire follows the injector that’s the issue. If the misfire stays at 3 you have another problem

[@FusionAspect]

I needed help with this decision i have a low mileage toyota celica trd gt, and i was wondering if it was worth selling for a 93 240sx manual with 174k miles and has all oem parts.

[@reddemon52]

the injector on the side that sprays I noticed it has a plastic or rubber little boot for lack of not knowing proper name I got the big rubber donut that goes on bottom and the o ring for fuel rail. I don't have that piece that goes on tips of injectors . what is the purpose of that? or I'm I ok with just the 2 rings in your video? it's for my 1zzfe celica

[@DavidRodriguez-eh7hy]

Do you ever try changing the intake manifold gasket ? Mine had that problem “idle” problem and I change it issue gone, 1zz engine.

[@2zzlow]

I actually changed it out to the updated orange one Toyota had. I believe there was a tsb for it but my issue is more fuel related.

[@DavidRodriguez-eh7hy]

How about when you took the fuel injectors did you test it maybe one was clog up, if is not that like you said it could be the fuel pump. I saw a video that the guy had same issue and install 2zz fuel injectors 😳 because the car was running lean.

[@Pallidus_Rider]

Is that injector OEM?

is it okay to use the blue injector came from 2008 corolla 1zz to my matrix 2003 1zz which is green? do they have the same measurement?

[@2zzlow]

Yea I’ve seen people use the blue injectors

[@iromero-ki8gt]

Anyone know if those orings would work on a 98 99 corolla fuel injectors the green ones also has the 1zz fe engine only difference they dont have coil packs but spark plug wires..

Thanks never worked on injectors.May look at.😂

You clean everything basically

Would those same insulators work for a 03 Celica Gt?

I don’t see why not? Same engine

[@kamelaouali7144]

Hellom thank you for this good video there are 4 injectors and there is one parts in the middle, [1.2 Injectors and there is this parts it's like sensore and 3.4 Injectors] what is his name and function

[@aaronbennack714]

Same question. Are you talking about the round thing in the middle of the fuel rail, on the bottom? I was wondering if that's the fuel pressure regulator

[@iromero-ki8gt]

Thats Fuel pressure regulator

[@jaylenjackson234]

Nice marketing quote 🤣 3:45

[@LogITECH-jk1ss]

Fuel filters go bad too they gunk up .and the problem is always its to old n the spark plugs always clog up w/ carbon.

[@haroldhirhalin1493]

You missed some steps buddy if you’re going to make a video make it thorough and complete you should’ve illustrated how the rail actually comes up and you never showed removing all the boats

[@fireyourrocketts]

You did not depressurized the fuel? does not show here

[@2zzlow]

You can if you don’t want fuel going everywhere on top of the engine but I didn’t do that myself

[@fireyourrocketts]

@@2zzlow In my case got a 2004 Toyota Corolla, manual reads to lift back seat to get to fuel pump, disconnect the electrical, crank engine to depressurize few times, then disconnect negative on the battery; it does not even mention the EFI fuse which would be easier but I guess there is a reason, have to do that this morning to replace those Chinese injectors I installed Nov 18 with the OEM ones which seems fine, measure yesterday and were ok because the cheapo ones are misfiring like crazy after 2 tanks of gas the first with fuel cleaner for the system; went crazy chasing all sort of misfiring codes and discover it may be injectors after looking the new iridium spark plugs looking newer than when were installed as car is running lean as hell; got to love this mechanic affairs!

[@realmenservegod8229]

Might not be a misfire maybe intake manifold gasket.....

[@2zzlow]

I have the updated orange intake manifold gasket

use petroleum jelly on the o rings
