1993 Chevy Cavalier

I have a '93 Cavalier 4 cyl. 2.2 liter automatic and I recently replaced 2 fuel injectors without following all the necessary steps to do so. I didn't realize that I needed to drain the fuel rail before removing the injectors. Now that I have everything replaced and put back together, I am having some major trouble. Every time I turn my car over fuel is pouring out of the exhaust. My car will not run either, it will try to start but it will not start and stay running. Did I completly tweak my motor or is there someone out there that knows how I can remedy my huge mistake? PLEASE HELP!!! Thanks so much!

Are you sure you replaced them with the correct ones? Are you sure you connected the wiring the right way? I don't believe draining the fuel rail will do anything other then spray you with fuel when taking it off the car. I'm pretty sure that no gas leaking out of the exaust pipe, that gas will probably hydrolock the engine and cause some major fires before it makes out of the exaust pipe.

Yeah I am sure they were the correct ones and that I hooked the wiring back up correctly. The reason I said that I should have drained the fule rail first is because when I got the replacement injectors (after I had pulled the bad ones out-I had them at the parts store with me) there was a little instruction sheet in with them that said it was critical to first drain the fule rail before removing the injectors or there could be engine damage. By the time I read that it was already too late. I am also sure that it is fule coming out of the exhaust because there is no mistaking the smell of fuel, especially when you get it all over yourself crawling around under the car trying to determine wether it is coming out of the exhaust or leaking out of a fule line somewhere. I am not yet a schooled mechanic, but have intentions of starting school next semester as being a mechanic is what I would really like to do with my life. I am just not completly car smart yet. Thanks for any input you can give me!~*~*~PurpleHaze~*~*~

If the electricals are connected in the correct order, and you see or smell fuel at the front of the engine you probably have a fuel leak somewhere and the system can't build up pressure.

If you don't empty the rail or relieve the pressure in the system you can have fair amount of gas shoot out under pressure when you take the injectors off.

Are you sure you don't have any fuel leaking in the front? Also, did you change all of the orings on the injectors?

what I have done since last posting...

I got some advice from a GM factory trained mechanic earlier and followed all of his recomendations. He said that I needed to change my oil and filter (if my oil smelled like gas) and that I needed to replace my spark plugs. I did both of those things and thought maybe that was going to work. However, I still have a large amount of fuel coming out at the tail pipe area of the car. It is not actually coming out of the muffler, but that is because it is running down at the front of the muffler and not at the back of it (back being where the actual tail pipe is). Upon noticing this I decided I better chck the oil again and sure enough it smells like gas again. Does this mean my car is shot or what??? Thanks again!

If the problem just started occuring after injector replacement i would suspect the problem is there, especially if the fuel rail is built into the intake and the injector sits down into the intake as alot of 2.2's are there is 2 o rings that seal the injector one at the bottom and one at the top of each injector if the oring on the bottom got pinched or damaged it will flood the engine with gas suggest checking them and replacing if needed.
