Is there a secret, simple, easy way to remove the injectors if you're not also removing the fuel rail (i.e, popping them up and out) without damaging them?

Loosen both screws with a vise grip when your car is cold (screws might be too soft for just a screwdriver):


Remove both screws and the metal cap. Then put the 2 screws back in (not all the way):


Use L keys or small screwdriver as leverage to "pop" it out:


You can see the damage to my injector from just using a vise grip on top (tried to pull it out that way but that didnt work)

Thanx, guys. I got the Phillips head machine screws out OK, and replaced them with Hex-head bolts (M5 x 16 mm - 0.80 pitch (metric)). Good idea about using the loosened bolts as lever-posts.
Oh, and BTW, for loosening those as well as other such soft, Phillips-head machine screws on the MAX (e.g., the ones holding the VIAS to the 00VI), I find very effective the hand-held impact driver I got years ago at Sears.

An impact driver is awesome on screws like that.

I just want to bump this and say thank you soooo much for this. I destroyed my old injecor and could not get it out. Put the screws back in and used to allen wrenches, popped right out. THIS SHOULD BE STICKIED!!!

I have a whole set of injectors I've been putting off replacing because I hadn't quite figured out how to get the ****** out. So they're getting done now.

It's stupid how easy it is after finding this thread. I literally DESTROYED mine and then they popped right out doing this.

And if you strip those screws, instead of drilling them out, just take a dremmel with a cutoff wheel and cut down into the head to make it a big flathead. Had to do that with one of mine and it was soo much better.

Ain't this some crap. Never saw this thread either. I was doing it partially right though by breaking screws with vise grip first. Getting the injector out, I used the same vise grip to hold top part and twist and pull at same time. Good thing those injectors were not getting reused. Is there a special tool for this?

Def neesa to be stickied. I went to the junk yard today to get some and couldnt get them out so said F it and went for the fuel rail. Damn idiots tried to charge me $35 for it and told me they cant and i cant take out an injector. Have to purchase the whole damn rail

oh yea this really gud i have a bad injector, tried to mess with this morning and it woundnt come out. i think im am going to go bck and try it again using this.

You are using bolts to replace the stock injector body screws?
Id like to upgrade those soft heads myself. I had to get some extras at the junk yard when I was doing some work(those bolts are used all over the engine).

Off topic; those fuel rails in the pics are pretty nasty looking. Lol

Thanks for the great tip! The L-shaped hex wrench along with putting back the screws helped me pull out the fuel injector very easily.

I had code P0302 (Cylinder 2 misfire) and white smoke was coming out of the exhaust that smelled like gasoline. My 99 Maxima (239,xxxx) had a rough idle too. I noticed this problem recently and the CEL came on really quick. After reading some threads on this forum, I knew it had to be the fuel injector since I replaced all ignition coils (OEM) and spark plugs (NGK Platinum) 3 years ago.

After replacing fuel injector #2 and resetting the CEL, the problem is now gone. This forum is great! Thanks everyone...

BUMP!!!

So i narrowed my misfire down to cylinder 6. Came across this thread and YAY!!!

My question is how can i test the injector? Put a screwdriver up to it and listen for the click? I know i can do a ohm test per FSM as well.

Food for thought I pulled 12 injectors for my 3rd gen today at the yard.


Remove screws (carefully they are soft metal)
Remove plate. ( throw across yard if applicable)
Then I twisted the injector
1/4 in extension with 1/4 socket and closest Allen head that fits into injector hole
Pry off another screw drivers handle while pulling up with your hand ( prevents injector and your tools going flying when it pops)

See photo (minus my hand holding injector as its holding a camera.)
