Installing the Injectors

Maybe try installing the locking clips back in? They aren't designed to be removed to allow disconnection. They have to be installed straight. If they are turned just a little bit, they won't connect. With the locking clip installed, its much easier to align the locking clip release point with the gold lettering on the plug. Without the locking clip, its just a round plastic plug which can make it difficult to determine how straight it is.
I've had a couple issues with them before, but never anything major. Just have to make sure they are straight.

If your picture looks correct, the connector must be turned 90 degrees about, to align so the retaining clips go throught he holes and then lock? Pic is a litte fuzzy, but thats what it looks like to me. You need someone more experienced than me at injectors, one of the techs preferably. Maybe one of them will chime in soon, I would wait till you get some advice based on those pics and make sure your o rings are lubed with clean oil ect.

Here is a pic of the injector plug. I have one injector that will plug into every plug on the harness. All other seven won't plug into any one on the harness. The top pic is the injector that will plug in. The middle is one injector that won't, and the bottom is the harness plug.

I can feel when they connect. I try to put the retaining pin in, but it doesn't hold. I mean it should be as simple as plugging them together. But they won't. There is only one way they go. I have the male slot and female slot lined up. If it is turned slightly it won't go down. It will push together, it just needs to go together another 1/16 or 1/8 inch. It's not a full connection. Something isn't right.

Put the metal clip on the injector before attempting to mate the plugs. This clip is not meant to come off. When installing the harness to injector, simply push the spring clip in a bit until the plug is in the correct location and then let go of the spring clip. The plug will no go as far as it seems it should because the injector side needs room to snap into the rocker box.

interesting. The connectors are also keyed male female so that they can only go one way, at least mine are. I almost always have to pull the metal clips to disconnect the injectors but have never had an issue putting them back together. They are harder to put back into the rocker box than to connect. Did you get a different set of injectors, although it shouldn't make a bit of difference in the world. Also, check the o-rings inside the injector connector to make sure they aren't different sizes. That may be the problem.

You don't need to remove the metal clips when connecting/disconnecting the injectors, EVER. Simply squeeze the metal clip downward and pull the connector out simultaneously to disconnect. To connect it, simply push the connector onto the injector until you hear/feel a "click" (this is provided the injector side on the connector is properly locked into the rocker arm carrier box).

I do it with needle nose vise grips. Arthritis sucks sometimes. Dropping a clip is definitely a bad deal. No extra's makes you extra careful. I lost one of the FICM cover screws checking the voltage last week. I knew exactly where it had to have gone but it still didn't save me from having to take apart a LOT of rubber flaps on the front end before I found it. Now if I could just find that last 10mm socket I'd be happy.

you have no idea how long i spent fishing out a clip. I dropped one lol. it fell in the only spot in the head that was like, 1/4" wide with only one way into the crevace. it took LOTS of patience and retries to fish it out with a magnet.
Anyways, I figured it out. Look at the first pic. The brown O-Ring is set into the groove. The middle pic the O-ring isnt in the groove. Well upon further inspection, the brown O-ring was put on top of the old O-rings on all of the injectors, except for one. The only one that plugged in. So I took out the O-ring, and vaula(SP?). It fit perfect. I knew I wasnt a retard. I mean it can only plug in one way, and it just wouldnt go down far enough. So now I'm on my way to tightening everything up. It sure would make things go faster if I could get the A/C thingy outa the way, but oh well. I took it apart so it can go back together.
Thanks for the concerns and ideas guys.

I just read your post. The O-ring turned out to be the right size, it just had another O-ring under it. Someone got lazy at RCD

Ahh!..Man, I knew something wasn't right! Working at a dealership, I install mostly new injectors, so reman injectors aren't as commonly installed. I had never run into this problem. It's nice to know what kind of problems are out there like this.
Glad you figured it out.
