Don't worry about the sound, Find the gas leak. Fuel lines come in on the drivers side. Then you have the injectors. on the fuel rail. on the fuel rail there is a pressure regulator. All this needs checked. Fuel lines on the engine are metal. BUT coming up to the metal lines, they are plastic. LOOK for wet spots.. FIX them. The regulator is on the fuel rail/ with the injectors. LOOK for wet spot at these locations also... There are also other locations under the car to find gas leaks....Fix this first...
engine hard to start smelling fuel first look under hood for signs leaking fuel lines if you raise hood get strong gas smell look for wet fuel leaks on top engine where fuel lines located.if see no leaks could have leak at fuel rails to fuel injectors.if see no leaks look under vechicle around fuel tank area look for fuel dripping.
Without looking at it, If there is raw fuel anywhere up top this is what i would do: 1. check rubber fuel lines on the intake. easy fix if leaking 2. check or replace the fuel injector o-rings they are $3.00 per set easy fix. 3. check cold start injector for fuel leak also easy fix
check top radiator hose goes to thermostat housing sound like its leaking if your engine leaking from left driver side on top of engine it has to be top radiator thermostat hose leaking.wait until engine cool down replace top radiator hose see if coolant leaking still occur if so you could have radiator leak.
You have to check for leaks under the car. Look at the gas tank, usually they leak but wont make it to the ground. If you see that the tank has any wet spots coming from the top around to the bottom, then the leak is at the sending unit. Follow the fuel lines up to the engine, looking for wet spots. Under the hood, find the fuel filter check this for wet spots, then check all the injectors, these can leak at the top or bottom, usually top. Best way to tell is start the car and then check the injectors. If they are leaking it could be a drip or spray.
LOOK UNDER THE HOOD AROUND THE ENGINE FUEL LINES LEADING TO FUEL RAILS FOR PETROL LEAKS AND LOOK UNDER CAR AROUND FUEL TANK AREA.LOOK FOR LEAKS AT FUEL LINES.REASON VECHICLE NOT STARTING FUEL LEAK TAKING AWAY FUEL PRESSURE.FUEL LEAK HAVE TO BE AT THE FUEL PUMP FUEL LINES OR YOUR FUEL INJECTORS OR FUEL RAIL HAS A FUEL LEAKS AT THE O - RINGS.
the hood of the Kia Shortage view the interior. From front to back you
will see the grill, the radiator, the radiator fans, and the engine. On
the top of the engine is the valve cover---an aluminum cover that
encloses the top of the engine---that is bolted in place.
behind the valve cover for an aluminum rail that goes across the back
of the engine. Inserted at equal distances---both below and into the
rail---are tubular injectors that are also inserted into the engine.
The aluminum rail is called the fuel rail. It is a hollow tube that
holds the tops of the injectors and supplies them with fuel. Each of
the injectors are also plugged into the engine wiring harness.
the injectors for any signs of fuel leaks. Although rare, leaks do
occur, especially due to age and mileage. If leaking, do not drive the car as there is an increased risk of fire. Repair the injector seals before driving the car again.
SMELL GAS YOU NEED CHECK ALL FUEL LINES UNDER THE HOOD IN THE ENGINE COMPARTMENT.IF GAS IS STRONG UNDER HOOD YOU DONT SEE LEAKING FUEL LINES.YOUR FUEL RAIL FUEL INJECTORS LEAKING OR FUEL PRESSURE REGULATOR O - RING OR DIAPHRAM LEAKING GAS.IF FIND NO LEAKS UNDER THE HOOD CHECK FUEL LINES UNDER CAR FROM ENGINE TO FUEL TANK FOR LEAKS.IF ALL IS GOOD YOUR EVAPORATIVE CANISTER SOAKED WITH GAS OR YOUR EMISSION EVAPORATIVE SYSTEM NOT WORKING. DEALERSHIP HAS TO CHECK AND FIX.
If you overfill the fuel tank, fuel can travel down the lines to the charcoal cannister located under the hood. This unit can become so saturated that instead of being purged and cleared by the engine, the vapour hangs around and can be smelled for days. It can become so soggy it drips on the ground and therefore dangerous. then it must be replaced. This is an expensive exercise.
your fuel injections lines in intake and injectors and fuel pressure regulator. could be leaking.look under hood.on intake where fuel pressure regulator. is look for gas odor and gas leak.if you get a strong gas scent you need to fix it quick.you got a fire hazard.
