Is the engine running rough all the time like the cylinder is missing "all the time"? A misfiring cylinder doesn't have to be misfiring all the time, it can misfire intermittently. An ignition module will do that. However, have it tested before replacing--they are expensive for your car. If you are sure you have spark, and have tested to be sure, then it is almost impossible to just smell to see if there is fuel getting into the cylinder. The only true way to tell if there is fuel getting into the cylinder is to take the spark plug wire off the plug and run the engine for a minute or two. Then stop the engine and quickly take out the spark plug. It should be soaked (wet) from fuel. If not soaked, but a little wet, it could be a blocked or failing injector. Let us know what you find.
