Question about 2005 Chevrolet Impala

2 Answers

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, couldn;t find anything wrong.He said everything looked dry and no visible sign of leakage. The mechanic couldn't smell the fumes, and looked at us like we were crazy. I said the fumes are there and they seem to be getting stronger each day we drive it.After a rain the other day there was water on the driveway when I parked the car over it to warm up.When the car was moved a few minutes later there was a gas rainbow with strong odor of gasin the water..This was leaking from the front end of the car..any suggestions?

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.

SOURCE: My 2001 impala shuts down while I'm driving

"Shuts down while driving "-------- This is sudden problem, it can be over heat or loose connection or voltage getting cut or any component getting over heated while driving.------------- This problems are intermttent problems, this are not permanent problems.----------- If its a permanent problem, then car will not start and run fine after few minutes.----------- In this problem the faulty component is not 100% faulty, but its weak component.------------ So to confirm, which part is suddenly nor performing, it has to be tested.------- When you face the problem, at that time, test the voltages, on that time itself.A handy volt meter , will be useful.The voltage needs to be tested from battery, starter, alternator , the ignition coils, the spark plugs and to the ignition switch.----------- Now when car suddenly shuts down at that time does it instantly starts or just turns over but dont start, do you hear fuel pump starting when you turn the key to ON.---------- In some cases this problem relates to O2 sensor.-------- . The o2 sensors are before and after catalytic converter.-------Both the sensors are to be replaced.------ And as per you mentioned your problem, its quite possible that faulty o2 sensor will cause this problem.------ O2 sensor is the part which sends signal to ECM( the cars computer).It sends signal to computer about fuel / air mixture.How and when to send fuel to engine.--------- If o2 sends stops sending signal to cars computer then it will not send the fuel to engine.------- In your case the o2 sensor must be getting overheated and this must be stopping the o2 sensor from sending signal to ECM.But when your car shuts off the sensor gets cool and again it starts working.------ So as per problem, get both the o2 sensors checked and replaced.---------- Also get the crank sensor checked.------------ Getting this possibilities checked will help.Test the possibilities when you face the sudden shut off problems.------- This will help.Thanks.Helpmech.

SOURCE: I have a 2005 chevrolet impala v6. In the mornings

you probably have the same problem i do with my car. My fuel regulator is leaking. I have to go have it replaced. It has taken us a year to find the problem because after the car is warm it doesn't leak. Good luck with it.....my car is the same year, make, and model. They must have just not made these very well. I have had one problem after another with it.

No service engine light? A loose gas cap will set a light.
You may want to inspect your fuel filler neck and anything close. For a long while its not uncommon for a person to report the fuel odor issue and have it be where some low life cut a filler neck or puntured a tank to steal fuel. But if that were the case there would usually be a service engine or gas cap light as the systems now days monitor pressures so they can detect leaks in the Evap system.

When you mention a smell though under the hood, do you think the smell could be exhaust? I have seen those manifolds crack. or maybe just a leak from a gasket or exhaust donut.

SOURCE: Help with gas fumes smell

Was fuel smell present before you had fuel pump replaced? If yes I would sugest you drop tank and see if fuel vent hose is plugged forcing fuel back pressure line to vent through cap. If fuel smell was not present before you replaced fuel pump and seal. I would suggest you drop tank back out and check all fittings and hose conections. also if you still have old sending unit you could check to make sure they are exactly the same. As Sometimes you have to pull relief valve from old sending unit and install it in the new one, as some sending units wont have one in it. and some will have one that is regulated at a different fuel pressure. hope this helps Vic

Why would I get a gas fumes smell when car is sitting idle or just been shut off. Cannot find any leaks in gas tank or lines


gas is a very high evaporative liquid..fumes extremely strong..if overfull it will smell..and if emissions equipment has issues it will smell also.. when the engine gets hot, any gas present will vent off until the engine cools..thats the fuels evaporative nature..still keep an eye out for issues..

The smell i'm having is not the raw gas smell , it smells exhaust fumes getting in the car. i checked for exhaust leaks buut had none


if inded the smell of exhaust is getting into your car i would suggest not driving it until it is properly checked by a licensed meachanic. it could be entering through your heater/AC blower and in return be fatal if left untouched for a period of time

It has a very strong gas smell when idling and after you turn it off.


Look under the car to see if you have any gasoline on the ground. If the odor is that strong, I would not recommend driving the car until you find the leak. Try to locate the area of the car were the smell is strongest, rear of the car, center or front under hood.
Carefully check all fuel lines with a flashlight and feel for any wet spots.
Good luck,
Let me know.

2005 Chevy Impala exhaust smell


neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.

2003 Chevy Impala Service Traction Sytem show on Dash


I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.
