When you turn on the A/c you'll smell fuel. I think i need to regulate the fuel control cause there is no leaking in the car.can i know more about fuel injection in this car ?

Possible leaky fuel injector/regulator/fuel line. Possible disconnected/loose fuel purge/vent line. Possible leaky fuel filler tube or fuel tank. You will need to have the fuel system/lines inspected to determine source of smell. Not something I would put off as a major leak could develop and spill fuel on hot engine/exhaust causing fire

over filling fuel tank will cause an oder of fuel also it will leak into evap emissions system which my radiate into car and usually if you had any kind of leak in the fuel system whether it be fuel lines or evap side it would throw a code and if you had a fuel line leak it should affect the way the car runs by not getting sufficient fuel pressure not sure you are over filling fuel tank but thats the only thing i can think of not knowing if you have MIL light on

Robin, if you smell gas you need to have that checked now!!! A fuel leak can result in a fire. Also check for engine codes and vacuum leaks The idle air control valve may be causing problems Hope this helps ,Bill

Well you know one thing, your air, spark, and fuel mixture isnt right at first start up. Sounds like a fuel pressure problem. Your fuel pump may not be hold pressure or fuel regulator on the fuel rail may need to be replaced. Regulators are pressure activated and use springs to regulate gas flow like when you start your car drive and idle. Also check for leaks or cracks in fuel lines as they can cause the same effect

Gas leaks are serious. If it was in the evap system the engine light would be on. So you need to check or have checked the entire system. From the top of the fuel tank, the lines under the vehicle up to the engine(mostly steel) At the engine they turn to rubber or hard plastic. Also check the fuekl rail and injectors. There are two Orings per injector. And check the fuel regulator. I lost my van to a gas leak that ignited from a faulty spark plug wire.

Unlikely it's the regulator causing fuel to be dumped into your oil. A stuck open or leaking fuel injector would dump fuel into your oil.

check for a leaking fuel rail,or injector,or the fuel pressure regulator,which is a vacuum operated valve at the end of the fuel rail.the high idle is caused by a vacuum leak,and if the regulator is leaking,that could be the fuel smell

MANY THINGS WILL CAUSE RICH FUEL MIXTURE PROBLEMS.LIKE INTAKE MANIFOLD VACUUM LEAKS.EVAP CANISTER FUEL SOAKED.LEAKING EXHAUST MANIFOLD AND EXHAUST PIPES.LEAKING EGR VALVE GASKET.FAULTY FUEL PRESSURE REGULATOR. FUEL CONTROL SENSORS OUT OF CALIBRATION LIKE THE ECT IAT MAF SENSOR AND FAULTY STUCK OPEN FUEL INJECTORS.

you need to take dealership have your evaporative emission control system check.also check the fuel pressure regulator for gas leak.most of the time the o - ring will leak.cause gas fume smells

That is a broken or rusted fuel line. It only leaks when the fuel pump is running.
