[EvilGoat]

Can anyone tell me or post a linkw in how to install 650cc injectors? i know i read it somewhere but i now i cant find it thanks. some people say it is a 2 min job is that true?

[Icecreamman]

are they plug n' play, or something that needs an injector driver?

I have 625cc's that were direct replacements for the stockers.

if they are plug and play then i do believe the removal of the fuel rail and replacement of injectors shouldn't take but 2-5 mins from what i was told..i've never taken my stuff apart but my friend who has said it only takes him 2-3 mins for his first time removing them

could'nt be easier dude, they basically snap right into fuel rail......take neg battery cable off....locate fuel rail.....undo fuel rail cover bolts they hold both the rail and the fuel rail cover ( there long black bolts right under the black cover that says srt4 on it)...gently pull and wiggle the fuel rail untill it pops off the intake maifold.....at this point the fuel rail should be off all four injectors will be stuck to the rail......each injector has a small metal clip that holds it to the rail, undo the clips and take off each injector, install new injectors....

If you need more room to install you can take the fuel rail off the fuel line at the grey quick connect right at the end of the rail... you'll see it, its a small grey thing with two tabs you push in on and pull off the line....

If they are just plug and play its pretty easy.

1.Pull the Auto-Shutdown relay in the fuse box under the hood. Crank the car up and let it die. Do it several times to vent the pressure in the fuel system.
2. Take of the injector cover.
3. Use a deepwell socket (13mm I think) to undo the studs that hold the fuel rail on (the same studs the cover pops onto).
4. Carefully pull the rail/injectors out of the motor. Have some shop towels ready as there will still be fuel in the rail, just not under pressure.
5. Pop off the injector clips with a flathead screw driver.
6. Pull the injectors off of the rail.

Reverse directions for install of the new ones. Don't forget to reinstall the injector clips when putting the new injectors on the rails. Also be careful to make sure the O-rings stay on the injectors, you don't want them to pop off and end up pushing them into the motor.

Hope this helps

there is a o-ring at the top and bottom of each injector. They seal the injector to the fuel rail and intake manifold. Make sure they are installed properly or you will have leaks

[Icecreamman]

The rubber rings are the O-rings, blue up top, black on the bottom. As you can see, one of the injectors in this pic is missing one.

yeah i can see that, thanks guys a bunch. This will help me not to mess that up

Most importantly, clear any and all debris surrounding the injectors before removal. If any of the crud that collects there gets into the engine you'll likely be screwed. I'd get a long wire brush and some canned air to clear the area thoroughly before removing the stockers.
