Hello i have a 97 sunfire 2.2l I have an injector that leaks it is the one on the 4th cylinder(closer to the driver) a few weeks ago i have replaced the orings by AC delco ones but the leak did not stop so i took the injector back and reaplaced the rings a scond time(just to be sure i did not snaped them while putting them in the first time) the seals were looking allright and the injector too. But the leak is still there. So my question is: Is it possible that the injector itself leaks even if i did not see any crack or anything on it?
And if yes is it ok to replace it whit a used one or if it is too risky?
And while beeing there is it complicated to replace the regulator and is it an expensive part(new)?
I had one leaking one that new seals did not fix. I did replace the injector and leak was gone. I did use a new one, as I also was worried a used one might end up with the same problem. If not right away, may not too long in the future. Also when I bought a new one, it came with new seals also.
That is good to know but i still want to know if t is a good idea to go for used ones or if it is realy so expensive to buy a new one.
ebay link....and for those that don't click its for 4 used injectors, for 50 bucks or so....i'd have bought them for spares if i had the money. but, the way i see it, 50 for 4 ain't bad. and they have a 30 day guarantee, so no need to worry if they work or not.
Injectors
and...if you do buy these and have the other three laying around, i'd be willing to purchase one from you since i have a bad one too.
let me know.

I had 2 leaky injectors on my 2.4 when I bought the car. Basically flooded itself when it sat for more than 10 minutes shut off, and failed emissions. My buddy had a parts car, so I took the whole rail off that car and put it on mine, all is good!
Finaly i just go to the junk yard and get one. But now if anybody has anidea to know if it is working right and how to clean it it would be apreciated.
When I did mine, the injectors that were leaking were still leaking and were making a hissing sound... so it depends how fast you can get your injectors out.
It's possible that it may not be the injector. My car had similar issues. The injectors on the 2.2 engine are side feed injectors. It is very easy to determine if they leak or not. In my case injectors 1 and 4 were bad. Injector 4 virtually fell apart in the mechanic's hand when he took it out. Injector 1 was cracked at the top, spilling fuel all over the pulleys and serpentine belt. Despite replacing both of these injectors I still had a strong smell of fuel around the engine and especially in the car. When I shut the car off you can hear hissing noises coming from the engine. So I called a favour from someone I know who works at a GM dealership and he had their most senior mechanic look at the problem. Turns out the injectors and o-rings were fine. What the GM technician discovered was the fuel inlet pipe seal was bad. He replaced the seals, checked all the o-rings again (I replaced all the injector o-rings when I fixed injectors 1 and 4 with new OEM ones), checked the pressure on all the fuel injectors and the problem was gone. No more leaks, no more smell of fuel. My regular mechanic would probably have never been able to find the problem. The GM tech cleaned everything with brake cleaner in order to clean the residue from the fuel that spilled and I'm hoping to get the entire engine shampooed later this summer. I don't know if this is related to your problem but if you replaced your injectors with new ones and you're still getting a strong smell of fuel, you may want to look at those seals as the cause of the problem.
The leaky #4 injector saga is not over but maybe on it's way. So after 2 oem oring installation the leak persevered. So the obvious solution was to put a new injector in it and that is what I did, well not a new injector but a junkyard one
. But miraculously the leak was still there but this time after looking closely i am able to see little bubles of gas escaping.
So what do we know now? First of all the problem is not the injector. So it might be the manifold but I think it is very unlikely.
But after a good reading of my haynes manual I think I have found the solution. I think the problem is that when I reinstalled the injector I did not removed the FPR but in order to do this i think i puted side forces on the oring and that i may crush one side of it. So my new solution is to remove the FPR prior to removing the injector bracket. I think this because there is probably a reason why they send the FPR oring whit the injector set. I am probably going to try this solution as soon that i have the time to go get a new oring set...
So first I want to know what you think of my solution.
Secondly I want to know if i will be able to put the fpr out of the way whitout removing it from the fuel line since I only have the o-ring for the ''rail'' side of the regulator in the o-ring kit.
Thirdly would it be a good idea to replace the FPR since it is probably not so expensive and that it is 10 years old?
OH and i forgot for the vacuum line on the FPR how do I remove it? I just pull and it release?
a fuel pressure regulator new will cost about 70 to 80 bucks- my car is leaking gas as well around the #2 injector Cant really see the leak itself but you can see the gas build up but I am unsure if its the injector itself or just the orings um - on my 2.2 ohv the FPR vacuum hose just slips right off. good luck keep posted

you should always remove the fpr before pulling that bracket, makes things alot easier...and yes, you can just unscrew the one little torque bolt there and pull it out. no need to undo the return fuel line. hope you can fix the leak, it must be getting annoying by now.
