SOURCE: Smell of gas fumes underneath vehicle near fuel tank

I also have a 2004 XC90 and a couple of months ago I had the exact same probelm... after multiple visits to my dealer's auto shop they figured out that it was the fuel pump. They replaced the fule pump and the smell disappeared. Good luck!

SOURCE: 2002 pontiac sunfire has check engine light

Your problem is typical for these cars. The throttle position sensor is bad. Go to Auto Zone and have them check the codes to confirm this. i've seen this many times, that's usually the problem. It makes the car feel like the brakes are on. Hope this helps. Let me know. Phil

SOURCE: Missing, stalling Pontiac Sunfire

The OBD II code for P0400 is Exhaust Gas Recirculation Flow Malfunction.
I'm sure the only thing you have left is you may have to replace the EGR valve or check for any leak from the vaccum lines going to to EGR valve.

Ok this only started once it got cold out. when I go and start my car to warm up there is an overwhelming smell of gas inside and out. It gets better as I drive but as soon as I have to start at a light or...

Firstly stop driving your car until fixed !! You may have a cracked fuel line or split fuel line. Your problem seems worse at lights because you are stationary with no air flow through your car to blow the fumes away. It is dangerous to drive as it is. All you need is a spark from a cigarette etc. Any doubt get it towed to a garage .

I have a 2000 pont sunfire and the check engnie light is blinking, not only that but it seems as if it wants to cut off when i am at a light or stop, it don't want to go when i push the gas peddle,I...

this usually indicates an emission problem that could cause motor or catalytic need to go to the shop and have code pulled from the computer to start diagnosing,the cat could be plugged up as you say when you try to accelerate the car won`t move normally,the gas smell indicates the motor is not burning fuel as designed and the white smoke indicates a possible coolant leak into the combustion chamber and being burnt.this car needs to be checked out at a shop before major damage occurs if it hasn`t already happened.

2000 pontiac sunfire starts only when gas pedal is held to floor, idles rough and white smoke comming to exhaust changed IAC change

If you have excessive white smoke coming from the vehicles exhaust, it sounds like your headgasket is failing. Especially having a rough idle too. Check your coolant level, does your exhaust smoke smell sweet, like Antifreeze? If so, the gasket has blown. Hope this helps...

Smells like gas when started and engine light came on. started after a gas fill up and continued to the next fill, light went out then at the next fill again the light came on. I have check the gas cap,...

get it checked it sounds like an EVAP code will turn up and have to be fixed as gas fumes are dangerous, to find and fix this you will need the system smoked .and tested by a shop with a scanner to test all the sensors.

I smell gas fumes coming from my car when i park and turn off the ignition

normally fumes come in to vehicle when stopped because of oil leak from rocker cover but check your fuel filler cap seal etc and also incase the tank is leaking just have a sniff at the rear of the car if its the filler cap or tank filler you normally get smell when tank is nearly full and been around a few corners the fuell filler nect becomes pourous and just spills out a bit if so will need replacing .but most time its an oil leak from rocker box or engine

My 97 sunfire smells like gas and uses too much fuel. Ive checked the fuel lines and there are no leaks. Now what??????

Check to see if your filler pipe is rusted(The pipe where you put gas in). Do you smell gas stronger when you fill up your tank?

2000 Pontiac Bonneville...gas fumes = Feul leak?

You know where you insert the Gas Nozzle to Fill it up? That is the Filler Neck and it can Develop Holes that will release Gas Fumes.
