Car wouldn't start with several attempts.
Finally started and ran after 4-5 attempts.
Drove to store, as we were almost there the engine died, we coasted the rest of way to our destination.
Did our business, went out, car started right up and made it home, which was only like 2 miles. Tried this morning it started 1st time. To scared it will stop and not make it back home.
It has never ever done this before?
Bought it used sept 2019. Previous owner said he just put a fuel pump in it.
Is it possible it is malfunctioning and going out?
Or is there an in line fuel filter between tank. An engine needing replaced?

Also when I fill tank up it doesn't take gas fast at all.
It took it fine when I 1st bought it.
6 mths after I bought it.
Now you have to fill very very slow, or it spews back out all over the car and ground.
Puzzled!
Seems to take an eternity to fill it up.

Thanks

Hi,

I suspect there is an issue with the fuel tank air filter. Over time, the filter gets dirty and prevents air from entering the fuel tank. If there is no air movement, fuel struggles to enter or exit the fuel tank.

I found a technical service bulletin (TSB) on this problem. It includes the directions for replacement. Before you do this, contact a dealer and see if it was made into a recall. I honestly can't remember if it was a recall or simply a TSB.

Here is the TSB. The pics attached below correlate with the directions.

CAMPAIGN - FUEL TANK AIR FILTER REPLACEMENT
NUMBER: SC092

GROUP: Service Campaign

DATE: January 2012

MODEL: 2003/2004 Sorento (BL)

SUBJECT: FUEL TANK AIR FILTER REPLACEMENT (SC092)

This Bulletin provides the procedure to replace the Fuel Tank Air Filter in 2003-2004MY Kia Sorento vehicles. Over time, the fuel tank air filter accumulates dirt, which can restrict airflow. If the fuel tank air filter is not replaced during regular maintenance the restriction of airflow will eventually reach the point where the vehicle may experience fueling difficulties. Kia is also providing an owner's manual insert for the 2003-2004MY Kia Sorento identifying that at a minimum the fuel tank air filter is to be replaced every 30,000 miles.
