1. Unscrew your gas cap to relieve fuel pressure.

2. unfasten two philip head screws for each injector. you may need wd40
and impact screw driver if screws corroded.(you may want to unfasten 2 10mm bolts that hold the electical bar, first)

3. push in on fastener and pull off electrical connection at each injector.

4. take a very large(larger the better) flat head screw driver and twist screw driver to pop off fuel injector. cover point of srewdriver with cloth to minimize damage.DO NOT USE A VICE GRIP. something like a chisel might work better than large screw driver. See picture to see where to place screwdriver head .

5.be sure to coat the new injector o-rings with vaseline.

6. place new injector in hole. place the point of large screwdriver on the injector top(on safe place) , gripping the screw driver lean in with your weight and give a push. the injector will pop in. Or use a 10mm socket attached to nut drive.

7. if only replacing o-rings, clean injector tail piece before putting injector back.

I bought my new injectors(4) from http://www.Deatschwerks.com for a total of $207 U.S. shipped to Canada taxes included. You get a $50 core credit if you return old injectors so injectors cost about $35each. Dealer wanted $1000. They give you new o-rings and grease free.

part no.: INJ-NIS1-370-4

If you use a large(very large) screw driver, they easily pop out. a large screw driver gives you lots of leverage(long handle) and the large head has more area in contact with injector.

any pic of the general area for the ground other than just a closeup? thanks!
btw, I'm in Vancouver and it'd be awesome if someone could help me figure this out.

I don't have an impact screw driver or a hammer. I used an electric drill and broke the magnic screw tip at the last one.
I resorted to cutting the washer out with a tiny saw.

I had a very clean and non-corroded rail, I still used this tool. It's a great tool for anyone to own...the modern version is the impact gun.

You don't need to pound the hell out it it (I used a rubber mallet). Also give a practice whack on a screw in some wood to make sure you are loosening.

I was looking at a $5 one at harbor freight, but the $20 one at an Advance Auto Parts was much nicer and should last a lifetime.

Outside of that, I just used a wide long screwdriver and was I pryed sort of rotated the injector while pulling. Easy. Removing the vacuum block (just unbolt it and fold it away) between the back two injectors make the job easier back there.

Also I don't trust the fuel cap method to relieve pressure. Pull the 15amp fuel pump fuse, start the car...run it until it stalls and then give it another crank. Pressure *SHOULD* be out, but like any pressurized system, esp. one you are troubleshooting *EXPECT* pressure to be found.

Busy day for me, did my injectors and compress/dryer/expansion valve in my wife's day.

beer time now.
