Can anyone tell me where the fuel filter is located on a 2006 Elantra? Also, my check engine light is blinking, and my car is having low rpm issues. At times, the car dies, and then it will turn over, but not start. Anyone have any ideas?

 

PS: Does the fuel tank have to be dropped to change the fuel filter and/or pump?

 

The filter is part of the fuel pump assembly mounted in the tank.

No, there should be a cover or plate under the back seat that when removed, provides access to the top of the fuel tank where the pump is installed.

You need to have a code scanner hooked up to the vehicle to extract the error codes from the engine control module. Many auto parts stores will perform this service for free or a nominal cost. You should do this first to figure out what the problem may be before swapping parts for no good reason.

I suspect you may have a failing crankshaft rotation sensor (which cuts off both fuel and spark to the engine when not functioning). A good scanner will pull the code(s) and run diagnostics on the sensor as well.

 

Hi Ken,
Thank you for your response! I had the code read, and it told me that the O2 sensor should be replaced. I replaced the sensor, and no luck!

 

What was the code? Did you change the correct O2 sensor? There are 2; one before the cat and one after.
