You'll need to inspect every inch of the fuel system for leaks. I would start in the engine compartment. Chech injectors, fuel rail, lines to rail,etc. Check under car for leaks in lines, around tank. Use you nose to give you an idea where to start. Since it fills the passanger compartment I'm betting on the engine compartment in which the fumes could get in through the heater intake which is close.Look for wet spots. It could also be a leak in the evaporative emissions system which includes charcoal canister, purge system and lines but you'd probably have a check engine light with a problem in those systems. The hotter the vehicle and climate will make the leak harder to find due to evaporation.

There's a gas smell inside the car.


Check your muffler for holes. The gases can enter the passengers cabin and it can smell like gas, specially if your car isn't burning gasoline completely due to bad tuning.

When driving i can smell gas in my 2000 lexus es300


possibly your O rings which isolates fuel injectors from engine block are getting old and letting gasoline go out. it is very dangerous since it can cause fire. do not drive.

another cause is broken loose or cracked fuel lines. this is equally dangerous since it is under hood close to hot exhaust manifold.

if smell is from exhaust manifold, which means not the smeel of gasoline but exhaust fumes, this can be caused by broken exhaust manifold or a crack on it or problematic exhaust manifold gasket.

An odor is coming on when I start my Ford expedition 2010 eddie bauer . It is just when I turn on the engine and start driving. The fumes are giving me a headache. I called my dealer and said...


from my experience, that is the smell of gasoline poorly burning at start up. getting into the cab that badly means that the climate control is sucking in fumes from the engine area, incredible this being a 2010. there also may be a leak at the heater core that warms up the cabin, basically coolant fluid fumes . definatly a warranty claim, something is very wrong here. pursue this with ford. battery leakage is total nonesense.

I have the exact same problem with my 2006 chevy cobalt right now. That's why I am searching this. I had a mechanic friend look at it and it's the fuel pump and the lines are cracked to. Has anyone heard of a recall on this? It can't be a coincidence that we are having the same issue.

Awful odor when 1st open car door after setting for 15 minutes


You should have the computer scanned for fault codes. Many times the engine is running to rich and causes the catalytic converter to overheat. This will cause a rotten egg type smell.
Can you post back with a description of the odor? Does it smell like gasoline or oil?
It also could be a carbon monoxide smell that could be very dangerous, it is a possibility that exhaust fumes are entering the cabin of the vehicle, this could lead to poisoning.
Let me know what you find and if I can assist further. Lone99star
