Rich or Lean???

Ok how do you figure out if you are running rich or lean and also i have another quick question . When i start up my car it smells like gas for a little bit for like 10 seconds then it stops but when its stopped or idling it dosent smell like gas only for the first 10 seconds after its been standing over night is something leaking? i dont see any gas on the ground and i checked the fuel lines nothing could it actually be because i have a messed up coil pack and wires right now? or my fuel injectors leaking or the fuel rail?

could it actually be because i have a messed up coil pack and wires right now? or my fuel injectors leaking or the fuel rail?

My guess would be...until those components "warm"up it could cause some unburnt fuel....
Is the smell from exhaust only?

The car will run rich on cold starts, its the same as the choke function on carbuerated cars. If its a real leak, you should find it asap. Look under the hood at the rail/injectors and all fittings right after you start the car, just in case.
