Because that's the only time that the fuel pump is operating.
Thus any leak is not likely to be in the fuel tank ... check the fuel lines and under the hood.
because your engine is going to break down or when you start the car if the whether is cold, it makes it smell like gas
i believe your heater core has died
You may have a oil leak, and oil us leaking onto the hot motor making that smell
I have the same problem on my ford taurus please help
sounds like a bad catalytic converter they produce a sulfur like smell when they get plugged up
More than likely a leak in the engine compartment somewhere..Especially if you turn the heat on and can smell you can be sure its coming from the front. If its only when the car is running then its probably along the fuel rail somewhere. If you can smell it just as strong when the car is off then its a line and your car probably does not get good gas mileage. start there or take to a mechanic asap! gas is way to expensive now a days!!
Our sense of smell only smells each different smell for 7 seconds
If you have a motor other than the car such as a lawn mower in the trunk it smells. Also if you just got gas it smells.
You normally smell the antifreeze so open the hood and look for a leak before you see it big time running out from under your car.
you probably have a leak that drains your pressure when it sits, and that's what you smell. it is not safe to drive with a fuel leak
Car exhaust can smell like rotten eggs when the fuel has a lot of sulphur in it.
A car may smell like sweat due to gym clothes, or other workout clothes, being left in the car.
