Top 10 2002 Kia Optima Questions & Answers

what i heard that it is like removing it from under the car which is not possible without lifting the 4 wheels. Also you may want to first do this before removing the alternator, even the multimeter shows the alternator failed test. Simply go underneath the car to check for the wire that comes out from the alternator and goes to the battery to charge it up. This particular wire that is coming out from the alternator to charge up the battery is completely fused or burnt.

i had the exact same problem, turns out, there is a 2 lines going from the gas tank to where you put your gas in, one is for the gas to go in and one is for air to get out. on mine, there was a sliver seal from a bottle of heat that i had poured in during the winter. the seal was the exact size of the return air line and blocked it from air coming out. this forced the air to come out the gas part and splashed around a lot causing the pump to shut off, i bet there is a blockage in the line that goes from your nozzle to your tank. it is easy to take off, but it is very dirty

I just changed my brothers on a 2001 kia rio. You have to go from the bottom. There is a tensioning adjustment on the top you have to undo, as well as a bolt on bottom. It is hard to get it out because there is not a lot of room, i remember it hitting either a p/s line or the rack, and being frustrated. I used a floor jack and block of wood under the engine and jacked it up to reposition it. It gave me enough room to get it out. Remove the bottom bolt and disconnect the wiring from it and it should drop out with some effort. Getting it back in was harder. Once you get it back into position connect the wiring before you bolt it up all the way, put the lower bolt in, put the belt on, then back to the adjustment on top. Make sure everything is tight and you should be done.

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.

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.

The speed sensor is located on top of the transmission Just under the Air Filter. So you will have to remove the Air Filter and you will see your two main sensors (I/O sensors.) . For more detail-----------
If you remove the air filter and look down on top of the transaxel, you'll see a couple of connectors that lead to sensors that are inserted into the transaxel. The Output Speed Sensor is the one towards the rear of the car, towards the driver. The Input Speed Sensor is the one a little hidden under a diagonal cable (with a boot covering the cable) right in front of your face. Thanks. you can rate this solution and show your appreciation.
