Grand am smells like gas inside the car

Lately I've noticed a strong gas smell inside my 2005 grand am. It seems like I only smell it when I'm idling and have the heat on. Any advice on what this could be?

    there is fuel leaking from a device at the right side of the engine, it is at the end of the fuel rail, I believe it is the fuel pressure regulator, but have not had a chance to verify

    My 2005 Grand Am also has the smell of gas when I first start up the car with the heat on. I had the fuel pressure regulator replaced and the car seems to run stronger but the gas smell is still there maybe stronger now. This seems to be a common problem with this car.

    I have the same problem when i turn my car on in the morning to let it warm up. i turn the heat on and when i get in it, it smells like gas but as soon as i start going down the road it stops smelling. But when i get out after driving it, the outside smells like gas. i have had my gas lines checked, my gas tank is not leaking. any idea what it could be? ive checked what i could.

    When I turn on the heat in the mornings to warm the car, there is a very strong gas smell as if I am at a gas station. It also smells very strong outside the car too.

I would definatly recheck the regulator to make certain you do not have any leaks.
But to be clear, you are smelling gas and not exhaust?
Also, is you cowl seal in good shape, not missing or damaged in any way?
Let me know.

Smell gas inside

On my 2004 Chrysler Pacifica I noticed a gas smell inside the cabin. I could also smell the gas very strong inside the engine bay when the car was running. It turned out to be a plastic line that connects between the fuel line from the tank, and the fuel rail which was leaking fuel. This line was located on the right side of the engine bay under the air cleaner. This was right next to the HVAC system, which was why I was smelling it in the cab of the car so much.

We also own a 2005 chevrolet impala with strong gas fumes, inside of the car driving or just idling..also fumes are strong when the car is just idlin. Took it to the mechanic and put the car on the rack,...

I would have someone check under the front of car while engine was running. Maybe then a gas leak could be spotted. Did he check the charcoal canister-it's a gas vapor collector from the gas tank, and maybe located at front of car. If the canister is full and not working to purge the canister and send the collected fuel and vapors into the engine, it might be what you are smelling.

When the heater is on there is a very strong natural gas kind of smell inside our 2005 Yukon Denali. It seems to come from the vents... and seems to be worse when slowing down or idling. Had the vehicle...

Check under the hood and make sure there are no fuel lines leaking.You should be able to smell it.If you don`t know what to look for the take it to a garage or your dealer and have them look it over.It is not safe to drive if you smell fuel while driving.It could cause a fire under the hood.Good luck.
