Thread: How the hell do you get the injectors out

Someone tell me an easy way. I took the caps off hoping they would kind of pop out and no, sprayed some sea foam to lube them up, no. took of the fuel rail hoping that was the problem no. My finger and thumb tips are killing me lol. Is there an easy button i missed?

I took them out by first taking the caps off and with 2 hooklike tools got one tool on each side of the injectors and pulled out slowly appling force. This was on a highport B13

I grabbed a piece of carbord box folded it so it was nice and thick put fuel rail with injectors bottom facing up then started hitting thwem with a hammer slowly and they will pop out but listen slowy or u will break the bottom plastic.... I was just tapping on them with cardbord box in between the hammer and injector

Turn the injectors to where the connector is parallel with the rail, put a flathead screwdriver under them, and gently pry them up.

We first spray all around between the injector & rail with PB Blaster while wiggling the injectors.
Then protecting the injector with shop towel, we lock on vise grips to the base of the injector.
Carefully by rotating the injector back-&-forth/side-to-side, pulling up at the same time,
and pushing-up from the bottom with your other thumb.... The injector will eventually pop out!!
Hand & finger muscle fatigue is a requirement for this!

You should avoid apply to much pressure to the plastic pintal at the bottom.
Age and due to the heat, they become very fragile with age and will easily break.
But they can be replaced by one of the injector cleaning services.
Most of the ebay ones dont fit... (ask me how I know )

yeah i broke one plastic piece so far using a tap lol


i tried the screw driver thing but these are so jammed in there that its chipping away the plastic, im just going to do the hammer thing i guess with cardboard on the bottom, im sure you can get the plastic pieces at nissan

lol i'll try that too, ive been using seafoam to wiggle it out

Nope Nissan do not sell the Pintals!! They want you to buy the WHOLE injector...
Seafoam is too dry... You need something more oily....

I really dont think that the cardboard and hammer is a good idea..
Unless you use something much softer between the cardboard and the pintals.
Several Layers of towels maybe... But, I personally wouldnt do it...
You may damage the spray head or deform the tiny spray holes!!

Oh.. I almost forgot this!!

Another Alternative...
You can really cheat on this!!

Just send the whole rail to the injector service for cleaning and testing.
They will properly remove the injectors, throughly clean them, replace the filter & pintals,
and do a performance test on them. Then ship them back to you in nice little ziplock bags..
Will cost about $50-$60 for the set IIRC..

i had to man, they were rediculously stuck in there, i couldnt use the vice grips because it was cracking the plastic sides of the injectors and i want to resell these lol
do you know any place online i could pick up those lil plastic pintals? and are sti injectors supposed to have them?

Yep... Call Tim at www.CleanInjectors.com (231) 598-1227

He's a great guy and I know he has the correct pintal caps..
Not sure about STI Injectors...

Good luck
