with the car off, pull out the fuse for the fuel pump, its located in the fuse box in the engine bay. With the fuse removed, start the car. its should run for a few seconds and die. with this done, remove the bolts and screws holding the fuel injectors and fuel rail assembly together. Pull out the injectors, and pull the upper and lower o rings off the injector. Take the new injectors and rub a little oil on them prior to installing them on the injectors, or putting the injectors back i nthe fuel rail assembly. install is the reverse of removal. reinstall the fuse, and start the car, checking for leaks.

How do you tell if fuel injector 0 ring is bad?
If there is gasoline leaking from around your injector(s) the o ring could be bad. Take out the injectors and examine the o rings. If they are worn, broken or cracked they are bad. If the o ring doesn't return to its shape when squeezed or is no longer cylindrical it's bad. Of course it is recommended to replace old o rings every time you pull them out so the best course of action is to simply replace them all.

1996 Sunfire had two injectors that were leaking fuel your mechanic said that they looked OK so replaced the O rings One is still leaking pretty badly Any Thoughts other than replacing the injector?
Re-seat them again and make sure the O-rings are new replacements for a proper seal Agree: I had two go bad in my '96. Replaced them both and used new O rings. It solved the problem. My mechanic used some Vasaline type stuff to lube the O rings when she installed them. I don't know if this is absolutely necessary or not, but they never leaked after we twisted on the injectors a little bit to get the O rings really seated. If the injector still leaks, I'd replace it. It's a $75 part, but worth the piece of mind and the improved gas mileage. Use a new O ring if you do replace the injector.
