Usually when a gas leak occurs. There will be a strong lingering gas odor or fuel may leak. If you can not locate the leak you may want to hire a repair shop to perform a "Smoke Test". This test is typically used to find leaks in the EVAP system but has other great uses as well. This test can help locate engine vacuum leaks and fuel tank leaks as well. You might also consider lowering the tank down for further diagnostic information. Any other questions feel free to write back. Good Luck.
OK, P0442 is an evaporative leak fault. The gas cap may well have corrected that issue. If you smell gas from the engine area you almost certainly have a fuel leak. You should be very careful - you don't want your car to catch fire and put people's lives in danger. When a car catches fire it goes up very quickly, and if it's near your home....
Look by the fuel injectors and fuel rail for signs of a leak. If you don't see anything there have a professional technician look at it.
lift the back seat and their should be an access panel on the floor pan where you gain access to the fuel sender which houses the fuel pump and i suspect that their is a leak here on the pressure side ,now if your unsure about tackling this type of job please go straight to a local mechanic to have a look for you as the vehicle is dangerous in this condition and could catch fire and petrol vapour is more explosive than liquid petrol.
excessive fuel pressure
breach in the vapor canister assembly (most likely)... this is near the gas tank
quick disconnect line near the tank is breached
filler neck is breached
Check and see if you have any gas on the ground after you park your car. Check around the gas tank and gas cap. It's possible that the fuel pump (which is in the gas tank) has hoses that may be leaking. If this is a slight leak, it might only manifest itself via a gas odor into the trunk or passenger compartment. It might be a good idea to put the car on a hoist and follow the fuel lines from the engine to the fuel tank. There should a one line that takes the fuel from the fuel tank to the engine and another that brings back the excess. There should also be another line coming out of the fuel tank that is for venting. Unfortunately, the fuel pump and hose connections are not easily accessible and require either removing the gas tank or cutting a hole in the trunk to access it. You should definitely take care of this soon as leaks don't get better, only worse and it is a potential fire hazard. Good luck!
do you have the same fuel economy as before or does you gas last less miles than before. if you can smell gas whether the car is running or NOT that means you have a leak in your fuel system if it was not a leak, you would not smell it when not running . first thing is check under vehicle after overnight parking and see if there is fuel on the ground if there is , this will give you a starting point where to look for gas leak. Plugged, dirty or poorly connected fuel injector; Leaking fuel filter or fuel filter connections; Punctured or damaged fuel tank; Loose or poorly connected fuel pump; Gas in gas can in trunk.
i had a fuel odor in my cobalt and after lowering the fuel tank i found one of the fuel lines coming out of the tank was cracked, while removing the fuel pump both of them snapped right off. way too brittle but a new pump and sending unit (all one assembily) fixed it right up with minimal difficulty and only $250.00.
hope this helps
do u have a check engine light on? do u overfill the tank? which is to say when the filler nozzle clicks off do u still try to put more fuel in? in any event u most likely have a overloaded carbon canister, pull the canister out and check it for gasoline saturation, the carbon canister is located under the car in a tray near the fuel tank.
