Fuel Injectors

[Dire91]

My car started to smell like gas on the inside and I found that my fuel injector was leaking. Now could I install this on my own having no mechanical experience or would it be better to take it to a shop? The shop wants $200 to replace each fuel injector thats bad on my stock 1997 240sx.

Fuel Injectors are so expensive even for the stock ones, car shop or stealer ship will also rob you, there are website you can order 'em from and trade in your old ones for some money back,

Or you can do what I did and buy some off Ebay. I think I got the whole set for $60 shipped, used of course.

injectors are easy, heres a quick run down .

- remove any obstructions, wires, strut bar, yadda, yadda, out of the way to access the 2 screws holding the injectors in.

- Remove the 2 screws with a GOOD phillips, has to fit good, other wise you will strip the screw.If you need leverege on the screw driver, grab onto the screw driver with a pair of plyers, push down on the screw driver, and turn with the plyers.

- Pop your old ones out with a flat head screw driver CAREFULLY, so you dont breack the plastick, or grab them with plyers, twist and pull. Screwdriver works best .

- make sure you got the O rings on the injector, should be 2, (1 small, one bigger) if you dont check the injector socket, get it out .

- grease the o rings (ONLY) no the whole injector, so that the new injector goes in smooth and doesnt rip up the o rings.

- place the screw cap on the injector, start one screw (dont tighten it down) then start the other screw, tighten alittle, then move back to the other, then back to the other, until you get them both tight evenly .

- Done

No just use an OEM injector, no some autozone or rebuilt ones they fail a lot, the trick it to lub the O rings that come with the new ones. Its an easy fix, if you replace one you should replace the O rinds on the others, just good it as far as how to lube them, but all you have to do is remove the items in the way remove the fuel rail, install injectors and re-install.

Also goog S13, fsm, nico and theres the FSM

also, i hit the junk yards weekly and pocket injectors from altimas (with the same motor) they work fine.

Thanks a lot guys Any good brand if I wasn't to get used, or OEM fuel injectors? Also how do I tell which one is leaking?

[s14derrick]

i can sell you some oem injectors dirt cheap. i just swapped out my old ka and i kept the rail with all injectors . if you want them they are yours i just need a few bucks and shipping moneys lol

[le_ryan]

before turning the car on, pull each spark plug out, the one that is leaking, should smell, either on the plug or in the hole. .

Located on the left side of the valve cover, correct?

straight awesome man. i have been needing to replace the O-rings on injector #1 and thought it was going to be a real pain in the a$$. and your tutorial thread is amazing.

Well I got bad news from the shop today, my fuel injectors are fine the car reeks of gas for some other reason. Also the water pump is leaking and the owner before messed with the "codes" so the check engine light etc... wouldn't pop up. Anyone care explaining that one, the guy who works there is going to see what the problems are tomorrow.

the water pump is designed to leak when the seal starts to fail. it has a small hole to let coolant leak so you know it is time to replace the water pump. good diy job. see tutorials.

I dont know about the codes but I have heard people talk about doing something to turn the light off so they can pass smog. gas problem is a safety issue.

my water pump leaked for years before i fixed it. but sometimes you only have weeks.

freaking hate ppl that fool with a re to mask a problem to pass inspection. one shop was totally going to let me slide with holes in my floor. I want to keep my car for years to come, no hack and halfass it.Anyway, did they check all the fuel line? and if you smell gas inside the car, I would check the trunk and the seal around the tank.

Well it isn't leaking out of the seal, the dumbass I bought the car from instead of fixing it or just saying it was leaking tried to silicone it and now it's leaking out of a different place.As for the gas smell thanks for the tips
