getting to the injectors???

[2002jm]

On the e30 323i, do you have to take the intake manifold off to take out the injectors, or is there an easier way?
thanks,

You can pull the fuel rail out with injectors attached without removing the intake manifold. You'll need to remove the cold start injector and the bracket below it as well as the valve cover.

Sorry for the hi jack, but if you remove one of the injectors from the rail (say if you wanted to replaced the o-rings etc) would a lot of fuel come out? I've been wondering this lately as I may be removing my fuel rail too.

To relieve fuel pressure on your fuel rail, pull your fuel pump fuse and start the car until it dies. Keep starting it again and again until it doesn't turn over anymore. When you go to pull the rail there will be some remaining fuel. I used a plastic bottle with the top cut off and tons of rags, but I may have been rather paranoid about it. Just clean it up best you can and let it evaporate.

Oh okay, thanks mate! :)

I didn't do the pull the pump fuse thing, some fuel came out when I pulled them, but really nothing that bad. Like Delfin said, just have some rags and the rest will evaporate. It's kind of hard getting a water bottle in there.

Don't forget to plug the fuel lines when you take the rail off. Also, I had a lot of crap around the injectors so I cleaned that area a bit before pulling the rail so that stuff doesn't fall into the injector holes in the intake.

Make sure to mark and put the fuel lines back where they were. Also - it is a little less tight in there if the valve cover is removed as part of the job. Good time to do a valve adjustment, replace the rocker shaft end plugs and put a new valve cover gasket in too.
