Question about 2004 Kia Optima

1 Answer

My 04 Kia Optima will start but then it runs rough. It acts like I might have trash or water in my fuel line. Does anyone know where the fuel line filter is located, also could this be a problem with fuel injector. I doesn't run like this all of the time. It will be rough for a week or so, and then it will run fine for a week or so and then the process is repeated. I have had it hooked up to the computer and it shows no problems. Any suggestions please?

Put a can of a product called "Seafoam" in the gas tank. Also do the following procedure.

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

SOURCE: Location of a 2002 kia optima fuel filter

Hi on this car the fuel filter is in the fuel pump so the pump as a whole will be replaced. To get to it you will have to remove the rear seat bottom cushion. There are 2 12m bolts inbetween the top cushion and the bottom. remove them and then on the front of the bottom cushion there will be 2 plastic clips pull up on them and the cushion will pop up and you will see the acc panel for the pump.

How to know if it is my fuel pump relay that is bad on my 2003 Kia Optima


normally this would be noticed by bad performance in the car in the way the engine acts when you push on the gas peddle normally a fuel pump needs two things to work the relay and the fuse if either two stops working you may notice decreased performance of the car's engine or that it refuses to run at all

04 Kia optima... I replaced broken timing belt and the engine turns over but doesn't start


Did you make sure the belt was installed with the timing marks lined up properly? If you forgot to look at the timing marks it will not start and you may damage the engine trying to start it.

FUEL BACKS UP AND SPILLS ON THE GROUND ON 04 KIA OPTIMA


There are no valves causing your problem. You have purely a plumbing isue. Some fuel stations pump fuel faster then the size and orientation of your filler tube will take. Don't be in such a rush when putting your 15 gallons in run the fuel nozel on slow.

2004 kia optima lx, engine will turn over but will not start.


The fuel line is connected to fuel injector Rail by 2 nuts (10mm) (from your right) next to air hose to air filter. Disconnect fuel line and start engine to see whether gas shoots out of the line. If not, fuel pump is broken. Engine turns over but not start , it could be iginition lost (no sparks ). or timing belt got rip broken.

Go to auto Zones (auto part store) borrown ODB II scanner loaner and take it home, hook to ODBII connector that's located at the driver side to your right. Read the codes given by the scanner and go from there.

If a timing belt is broken, open timing belt cover to check on the belt.

If your belt is broken and crushed apiece, you may have to rebuild the whole engine as it's an interference belt.
