Trouble removing injectors -Legacy 94 EJ22T

Post by Dave G »

I have the screws out and the caps off. The manual instructs me to twist gently and pull. Twisting is not happening. I don't want to break any plastic bits. 128,000 miles and these have never been out before. Any tips to loosen them up?

they're a pan in the ass to get out!! I ended up using some pliers. Just work at them carefully with the pliers....that's about all I can suggest. Maybe squirt some penetrating oil around the seals first.

I haven't dealt with EJ22T injectors before, but I have dealt with non-turbo ones, and I definitely agree that they don't just twist-and-pull out.

It can help a little to dribble some quality synthetic motor oil around the edges. It penetrates in and helps lube the o-rings.

You do need to get them to twist. That'll break the seizure between the o-rings and the fuel rail. Just be gentle. A pair of Vise-Grips that fit neatly over the top of the injector are a big help.

Then you just need to pull really hard. Really really really hard. It may help a little to remove the fuel rail from the car and push carefully from the other side. But you may need to bolt the fuel rail to something stationary in order to pull hard enough.

I have been struggling with this of late myself. I was advised to use an air compressor on the side of the rail while blocking off the other end. Pop...#1 comes right out. Then grease it up, put it back in (with the cap on it) and pop #2 the same way. Then you can remove them both and do what you need to do...

Woah, that's a really cool idea! Just put down something soft for it to land on. :)

Would plugging the fuel pump back in and turning the key on have the same effect?

If you use the air method.....you'll need to plug the other side of the fuel rail.

Dave.....DON'T try and do that with the fuel pump....one it probably won't work....the pump only puts out about 40 psi vs. the compressor's 120 psi. Second....that's just not safe :)

What if I have the 255lph fuel pump? How much pressure does it make? :D


LOL

Sounds like a good idea (with air) I'll try to remember it.

Vise grips are the trick. I got the front two out. I need smaller grips or channel locks for the rears. i bent the plastic a bit on the passenger side. Must go watch Pitt-WVU game now.

The same, the fuel pressure is regulated by the pressure regulator, not the pump. The pump that you have just gives your car the ability to give more pressure when the regulator requests it.

Got the last one out

Post by Dave G »

Recent knee surgery has delayed the end of this project. The fronts aren't so bad, but the rears present a special problem. I removed the air filter housing as well as the w/s washer reservoir to get some elbow room. Still, plumbing gets in the way of a good grip and pull. After screwing up the driver side rear injector pretty well, I was faced with the right rear. I really did not want to pull the fuel rail and face a host of new problems. Ultimately, I simply rolled up a shop rag, spun the injector so the connector was facing straight up, tucked the rag behind the connector , and gave a firm yank. It popped right out (flew out is more like it, so be careful).
As for the other injector, has anyone used injectors after the plastic housing has been bent/peeled back where it meets the metal of the injector body?
