replacing injector in Cavalier

Could someone walk me through the procedure/give me tips on how to replace one sole fuel injector in a 95, 2.2 Chevy Cavalier (160,000 miles)?

Have a case where I'm smelling a strong gas smell from the front end. Tracked it down to a fuel injector, around which I could see drying gas. So, I would think that I would have to replace just this single injector...or would it be more likely to be the o-rings I keep hearing about. Regardless, I'm unsure of the procedure. The Chiltons manual has me taking apart the entire fuel rail, which I'm sure I don't need to do but am not sure how to proceed.

Any help would be appreciated.

Hiya...

Which end of the head is the fuel residue found? Drivers' side or passenger side? If it's passenger side, that is where the return pipe for the fuel system is. I know from experience that if that pipe is not seated correctly, or the flange that it bolts onto the manifold with develops a crack OR the o-ring inside the pipe is shot or unseated...fuel will leak out of there quite steadily once the fuel pump is switched on. It's a common pain every time I've disassembled either the head or the manifold, or both...but it's an easy fix.

PS: If it's one of the injectors...well, that's one I haven't done yet...so you might want to go with a Haynes or Chilton manual for it. I prefer Haynes, as Chilton is generally written for someone with a well-equipped shop, where Haynes is written more for an average shadetree mechanic with more generalised tools. Good Luck!

The leak is on the driver's side, closest the fuel pressure regulator.
