Changing one injector?

I will have the passenger side valve cover pulled to check the UVCH in an effort to figure out my P0273 code. I have another thread about that here.

I have seen disdented threads where folks advise that in the end the injector itself was the actual problem irregardless of the code being electrical.

I want to do everything I can while that valve cover is off to avoid having to pull it again any time soon.

So are there any issues with replacing the one injector while in there?

Is replacing one injector difficult?

If that is ok, any tips.

Thanks.

I read so many threads...I'm not sure if yours was the one where they mentioned to replace them all if you have to replace any

I also feel like you don't need all these threads you are starting and could ask these questions in your main thread...I might just be on edge today... and yes, one injector can easily be replaced, swapped, etc. Same process as you would replace all of them.

I hate when people say don't start multiple threads when there are multiple questions going in different directions where a good amount of detail is required for each unique question and asking multiple questions in the same thread can derail the entire thread.

I support multiple threads as an administrator in my vehicular community for that reason and things keep flowing but whatever.

...and no that was not my thread but even if it were then life goes on.

Maybe... In your other thread you said you don't like using swivels, so not sure what your mechanical abilities are.

Triple check your work and take your time.

Thanks, I have been working on vehicles for a long long time and have done many complicated things. I just feel like one day swivels worked for me and suddenly they stopped working well for me. Almost like plugging a tire. One day I was always able to plug tires and not have them leak then one day I was never able to replicate that again.

These days I use a manual tire changer and bubble balancer to balance these wheels and tires to perfection. I hope that gift never goes away.

I feel like I gain valuable skills then lose them. Sometimes I lose very trivial skills. Inability to use a swivel is probably pretty bad, lol. Just feels like I try to turn with them and they bind, I lose patience trying to figure out what silly thing that I am doing wrong and move on.

Is the code intermittent under hard throttle, or is it always present?

It is always present even with just the ignition turned on. Here is the thread and where I am at this morning:

Understood and I am the same way. I work on my own and friends vehicles out of necessity and finding a good, honest mechanic in 2025 is difficult. Perhaps try a wobble socket or adapter if the swivels have turned on you. I try not to use wobble or swivels, but sometimes there is no other choice.

It is rough. I am going to pull all of what I perceive to be "swivels" a bit later and post them here then maybe watch youtube for reeducation. Maybe there is something like how to use a swivel out there. Maybe I am calling them the wrong thing.

Ohm test it all, start at vc gasket, then from the 42 in plug, then back from the idm plug, if all ohms out good, you can try swapping solenoids if you havent already. If code still presents itself, send the idm to diesel tech chatt for testing.
https://www.dieseltechchatt.com/coll...42720423641264

If all that all checks out, then I would check armature screw tightness and armature clearance.

i would move the injector to another position first and foremost to see if the problem moves with it. if it moves with it then change it, but even then unless you changed them all 10-20k miles earlier I would change them all at once as if they are original and one is going....

I think this happens to all of us...there are a lot of things I used to be able to do that i fight to do now or just plain forgot how I ever did things

I thought he tested the wiring but can't recall. He wanted to do one last test before he sends his IDM off.

He is working on a different variation of swapping injectors...he is going to swap the wiring instead of pulling the injectors.
not sure if Erics method of swapping solenoids is the same; if so...that would be better than cutting into a perfectly good harness. After he mentioned it, makes sense that swapping solenoids would do the same thing

There is no issue with replacing just one injector if it is faulty.

Installing an injector is not that bad, the worst part is getting everything out of the way and getting the valve cover off. I went and got the OTC injector removal and installation kit mentioned in the shop manual and that did make the process very easy, you just have to tighten a bolt to both remove and install the injector. Make sure to be careful when putting the new O-rings on the new injector if they are not already installed and oil the O-rings well before installing the new injector. Don't forget to check to make sure the old injector's copper washer isn't stuck in the injector cup before installing the new injector. Make sure to suck out the oil and fuel that leaked from the oil and fuel rails into the cylinder after the old injector was pulled, and pull the glow plug and bar the engine over a few revolutions to blow the remaining oil and fuel out of the cylinder before you install the new injector (put the valve cover back with a couple of bolts on before you do that.) I used a 60 cc vet syringe from the farm store and some 1/8" ID vinyl tubing to suck out the fuel and oil, that fits down the glow plug hole nicely and worked well.
