The smell that you are getting is a result of your fuel jets are blocked with a foreign body, check your fuel jets. Depending on the age of your vehicle they will need to be replaced.
the smell is caused by unburnt fuel leaving the engine as you are cranking it nuthing to do with blocked fuel jets. if fuel jets are blocked, you wont get fuel at all. u might check condition of battery to ensure engine is cranking at correct speed . if battery is low, engine takes more cranking to start hence the fuel being lost .
i think u need to change the O2 sensor in this case.check the air filter if it is bad.
My urine smells reaaly bad what can be caese it
Leak in exhaust system?
don't ever smell your car's exhaust.
because of the exhaust
The car exhaust smells like the rotten eggs as a result of the hydrogen sulphide. This usually happens, when the engine is not serviced for a long time.
probably an exhaust leak, at or near the exhaust manifold
http://www.autozone.com/servlet/UiBroker?UseCase=S001&UserAction=viewSimpleDiagInfo&Parameters=info sounds like you need a new exhaust system. exhaust also may not be quite long enuff and is letting fumes into trunk of vehicle a good exhaust shop can check this for you in a couple of minutes
Likely an exhaust leak
Most likely your exhaust is rattling and the smell is because your catalytic converter is bad
Sounds like you have a coolant leak.
I was just in Mexico and some of the common smells that I smelled were cooking foods, flowers, car exhaust and garbage. These all depended on where one was in Mexico, when I was in Cuernavaca, it was mostly food and car exhaust in the Zocolo, the city center, but flowers where I was staying. In Mexico City, there was more of a garbage smell while riding or driving on the highways and car exhaust and food smells most other places.
