I use vaseline all the time.....On the Fuel injectors o-rings,....that is!

 

hey i'm about to attempt to replace one of my fuel injectors on my 94 maxima. my engine looks a little different then the one in the pictures. does anyone know if there are anything i should do differently anything i have to know about my engine thats not explained here. my engine is a vg30e. thanks

 

What's different about your motor? Sure you don't have a VE?

 

YES! finally, after nearly 2years of just sitting there (95% slacker, 3% looking, 2% doing )... I've gotten the air plenum off!!!

I was initially going to use a wrecking bar and just get any point and just "fulcrum" it off. But as I was shopping for a wrecking bar ($10 for a 24"), I was thinkingThen I thought of this!


with a few upward thrusts, it popped off! Jubilation ensued


Looking at the RTV that I put there, it didn't seem like much, but as you all know, RTV is some resilent stuff.

Anyway.. time to attack the collector, pull the fuel rails off, and get them injectors DONE!

... just wanted to share
Happy driving!

 

 

Good job there MacGruber! I am actually doing my car again. #5 injector went bad. No RTV for me!

 

Hi i just recently replaced 2 Fuel injectors in my 1990 Nissan Maxima. After replacing 2 fuel injectors, fuel pump, and brake booster, the engine wont 'start". It turns over and will start for say 1 second or 2 then die, and from there will only turn over but not start. I also recently purchased a Duralast battery (2 months old new from autozone) Help?

 

Hi all, thanks a lot for your nice and kind help. I have a 1998 Maxima GXE. I am doubting that one or more of my Fuel injector is bad I am wondering does anybody has a video or a detail instruction series with photos to change just Fuel injectors (not the rail) for 4th gen maximas ??? I appreciate all your help guys in advance.

 

I know this thread hasn't been active in a while, but I'm hoping someone will see this. I had a dealership tell me I needed to replace #2 and #5 fuel injectors and charged me $800. They said they reduced the labor because they didn't have to remove the plenum. The car runs poorly and I think they didn't want to get into a 17 year old engine's plenum. Is there any way they could replace the #5 without taking off the plenum?

 

Dudes,

Thanks a lot.. I have been helping a friend to get his injector changed. upon reading on the stuffs above, I feel confident we can be able to do it, and we just did. All are DIYs...

Regards.

 

If I have a bad injector on my 1993 Maxima, will it throw a code? It was running fine, then suddenly started running-idling rough?

Thanks

 

Hi Kiron, I am a learner, but from the chilton's manual, there are self-diagnosis codes in Mode-III for fuel injector issue (45 - Injector Leak, 51 - Injector circuit) But these only apply to the california model. You could try checking the resistance of the injector. They should be between 10-14 ohms which seems to be the valid range. But there could be several other reasons for the engine to run rough. This forum has a lot of good info. Maybe run some searches with specific keywords for the issues you are observing.

 

I noticed that the link to the tutorial has died. I was able to access it using the Internet Archive "Way Back Machine." It will work for now:

I took a copy of the tutorials HTML and images. I may post it up somewhere else to help out the community in the future.
