I have a 96 sunfire with a 2.2L. It has 270K miles. One of the fuel injectors was leaking so I put a new injector in the 2nd cylender I put it all back together and when I tried to start it, there was gas flying out of the exaust linkage right at the engine. I removed all the spark pluge and the 1st cylender has the gas flying right out of the spark plug hole. none of the rest do this. and it is the one right beside where I replaced the injector. I put another injector on it then and t still spews the gas right out of the spark plug hole. Any ideas?

I live two hours north of you in Nashville. I found your post through google. My 96 sunfire 2.2 liter 161k engine has one injector leaking that I found today. I started looking when I was smelling raw gas with the heater on. I was going to attempt to replace it myself, but after reading your post, I think I'll leave it alone and drive with a fire extinguisher

I have a 1995 Pontiac Sunfire SE 4 cyclinder 2.2 liter with 176,000 miles on it. The fuel injector(s) needs to be replaced. Any suggestions? The car smelled like it was on fire and stalls.

Make sure you replace both the upper and lower o-rings on each injector. Do not adject the rail by bending in any way!!!

I have the Ame car 96 sunfire 2.2 liter I replaced all of the bottom orange and top when I put it back together the first time it was leaking right into my cylinders so I took all the plugs out and got as much of the gas out as possible but it had already put a ton of gas inside the motor so now I have taken it apart again and I have orings from work they are very similar but the most recent ones are a little tighter to the bottom of the injector and they are a little bit wider so I put it all back together again. So I went and bought a fuel injector pressure tester and I am going to hook it up before I proceed to roll it over anymore and make sure the pressure is in the fuel rail I have also drain the oil and it was heavily mixed with gas and I'm pretty sure I failed at least half of my spark plugs so I'm going to replace all four and that I hope that I did not cause any damage to my motor to anyone out there going to put seals or new injectors in this motor2.2 OHV. I suggest taking it to a garage it sounds simple enough but it is well honestly one of the hardest things I've ever done they just don't seal properly. If anyone has gone through a similar problem like I have and has come up with a solution can they please comment on this post I'm not sure if my car will never run the same again with the existing motor thats in it but I hope it does I will update my status tomorrow.
