I also had the same problem with mine and I had to replace the gas vapor solenoid valve. Its located on the intake between the firewall and intake . $14 dollar part is all it is. When you turn your key to the on position and this solenoid is stuck open it allows built up gas vapor pressure to come in from the gas tank and causes the engine to flood at idol speed . That is why you have to peddle it to keep it running

SOURCE: 2004 Kia Sedona wont start but i can hear starter.

if the starter is revving very slowly it is the battery, charge battery. if not, It can be three things happing. 1 no spark 2 no fuel 3 no crank signal or the car computer is bad- you will need to unplug one of the spark wires and remove the spark plug and put the spark plug in the spark plug wire boot, and touch the spark plug on any metal on the car and have some start the car. donot touch the spark plug itself and see if there is a spark. if spark is bright, then it is not spark plug and wires but if no or spark is not bright, check the spark plug wires by applying a little bit of water on the spark plug wire and take a 12v test light, connect the clap to ground and and have some one to crank the vehicle, touch allover the spark plug wires with the tip of the test light, if you see spark, replace the wires and change the plugs.. they are not good. if spark is present, check for fuel by removing any one of the spark plugs and see if it is wet. if wet fuel pump is ok but if not go look for the fuel pump fuse and relay. is fuse blown, replace, check the relay resistor with a volt meter. it should be around 40 to 80 ohm. if everything is good from this point check the fuel pump itself by disconnecting the connector to the pump and apply 12v and ground using jumper wires or some wires to the fuel pump if you donot hear the pump,replace pump. if you, the crank signal or computer may be the problem

SOURCE: my 2006 kia optima airbag indicator light stays on

my advise to you is not to attempt a repair to the airbag system yourself. The airbag module can be set off by static electricty & goes off with the force of a shotgun blast

SOURCE: The airbag light in dash staying on in my 2004

Under driver and passenger seats are wires that go to seat belt anchors.These are tensioner wires.Unplug the wires from the plug under the seat.clean and replace.Doing this while the ignition is turned off.Then turn ignition back on.In 90% of the time this is your problem.Constant movement of seat causes this or rear passengers kicking plugs off.Good luck phil.

P1529 and P0720 does not seem to be understood.

P0715 means Input/Turbine Speed Sensor Circuit Malfunction.

P0118 means Engine Coolant Temperature Circuit High Input.

04 kia optima starts, but wont stay running.


The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exceptions to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

Start with the simple and replace the fuel filter. The fuel filter should be replaced every 15,000 miles or once a year to ensure the fuel system is running 100%. Auto Zone will have the fuel filter and can give you the step by step instructions to getting the job done with common tools. If it's the fuel pump failure, you have not gotten the car restarted. Good luck and keep me posted, be glad to know you got your car running 100% again soon and please rate.

2004 optima wont stay running after fillup


semms to be like some of the vapor lines coming from thank to engine might be flooding your engine,
but also locate the fuel pressure regulator at the engine compartment and unplud the vacium hose, if you see any fuel coming out from fuel pressure regulator, or if the vacium hose smeel like fuel, then the regulator is not good.
