08 Fit. We left it sitting in the dirveway for a while, and I pulled
it in in the evening. The engine probably ran for 45 seconds, max.
When I got out, there was the strong smell of unburned gasoline. Was
this just a startup artifact, or maybe a cold run (the funky little
blue thermometer was still on)?

Could be either the rich mixture typical of startup or it could be a fuel
leak under the hood when cold. Those fuel leaks can be devilishly hard to
see, but if you get a repeat of the gasoline smell it is worth sticking your
head under the hood to see if the smell is stronger there or if it may just
be from the tailpipe. I had an engine fire from a leaky injecotr once, so I
take those smells rather seriously now.
oh puhleeeeeeze - is this a chicken little competition?
when a car starts, you have to dump gas because the motor is not warm,
thus the fuel doesn't fully vaporize, thus you need excess gas to get
sufficient vapor density to burn. if you dump gas, then turn the motor
off? where is the gas now? in the inlet, and /not/ being sucked into
the motor. so where does it go? it evaporates back out of the air
intake. thus you smell gas!!!
so that's all the o.p. is experiencing - a few seconds of excess gas
because he hasn't warmed the motor. utterly trivial.
well, the neighbor kid could have been stealing gas too and spilled
some. or theoretically, the vehicle /could/ have been drilled by one of
that actually /did/ interact precisely at an injector o-ring, and is
subsequently just a bomb waiting to explode.
but somehow i doubt it. just like i doubt fuel leak on a sub-year old
car made by a manufacturer with an excellent track record on this stuff.
especially when we're told that the car has been run for less than 60
seconds and that we know about excess mixture on start-up, etc...
seriously dude, look at the big picture and assign probabilities.
I'm most suspecting fuel injector failure - separation at the plastic/metal
junction. That can occur at any age and mileage, often shows up when cold
and may stop leaking when warm, and I've seen quite a few in my time...
including the one that set my Nissan on fire before I could put the new
injector in. On a nearly new car the possibility of a construction defect
can't be discounted either; that is why the warranty exists. I am not
advocating a witch hunt, just due diligence for something that can easily
send the car up in flames.
Personally, I would feel less silly looking for a leak than I would looking
at the charred remains and trying to answer the question, "why didn't you
check it out?" To each their own.
Since the OP apparently does not have the mechanical knowledge or skills to
look for the cause of the smell the only real solution is to take it to the
dealer and have it checked out for safety if nothing else.

hey, can i have another "tempest in a teakettle" drama queen over here
please? this one's simply not histrionic enough.
The point is it certainly can happen - there is nothing inherent in Hondas
that exempt them from the possibility of engine fire. The smell of gas
(should *never* occur with port injected engines) is a big red flag.
Something is wrong.
no dude - did you not read what i explained about exactly /why/ it
occurs after a very short run like this??? true, it shouldn't occur
after a warmup, and in that case, you /would/ investigate, but after a
few seconds cold? gas stink is /inevitable/, and for the reasons stated.
Nope - and if you give it a try you will notice there is no gas smell unless
you have a fuel leak. In fact, it makes no difference whether the engine is
running rich (cold) or is warm. The fuel sprayed into the intake - whatever
amount - is ingested with every stroke and stops before the engine stops
turning, meaning the fuel is cleared away and never escapes.
In the old carburetor days it was common to smell fuel when cold, especially
if the engine was flooded. The fuel collected in the carb throat, more so
when cold because of the choke, and the fuel did not stop when the ignition
was turned off. TBI also injects mighty close to the outside air and can
produce a gas smell (although not what I would describe as "strong"), but
not port injection. Lord knows I've changed enough air filters after pulling
the cold car into the garage to know there is never more than a faint trace
of gas after the filter is removed, and none before.
not when the engine is cold. wet fuel lines everything south of the
injectors. and if you start, then stop immediately, it never gets warm
enough for it to instantly vaporize, therefore it /cannot/ get "cleared
then you're either not running on gasoline or you're in denial!
Try it and see.
I'm surprised nobody else is weighing in on their experiences with gas smell
or not. I know none of the 5 cars at my house have gas smells even after
rearranging them, which we do pretty much every night in the winter when
street parking is prohibited. Two always end up in the garage and it never,
ever, ever smells of gasoline. I even asked my wife, whose nose is better
So, you still haven't checked it out for yourself? Go ahead - science isn't
painful. This morning when I pulled my 2002 Prius into the garage after my
wife left (it had the same sort of run time the OP was describing) I opened
the hood - no gas smell. I removed the air filter cover - no gas smell. I
removed the air filter - no gas smell. I put my nose to the throttle body -
faint smell of gas and crankcase odor. I'd say your theory of gas smells
normally coming from the intake when the engine is cold is busted.
I am curious about what you would check out and what you would let ride.
Many oil pressure light indications are the result of a bad sender; do you
routinely ignore them? Engine temp lights and guages could be wrong, too.
Clattering sounds coming from the engine could be innocuous. Smoke from
under the hood can be anything. Diving momentarily to one side when braking
may be a sluggish brake caliper, not a ball joint failing
http://tegger.com/hondafaq/lowerballjoint/index.html . My point is that a
gasoline smell is going to be the only warning any of us would be lucky
enough to get before a fire that will destroy the car and, if it is parked
in a carport or garage, may destroy a home. It is hard to imagine a worse
outcome short of a failure that causes a crash.Why on earth would somebody
choose to ignore it - especially if the vehicle is under warranty, as the
Several years ago the entrance to our parking lot in Phoenix was blocked by
a Cadillac. That afternoon I asked the guard what happened. He said the
driver tried to make a U-turn and a ball joint broke. After the guard
determined what the failure was, he asked her, "Didn't the steering wheel
shake [pantomimes] when you went over railroad tracks?" She said, "Yeah!
Just like that!"
