Make sure the filter that was put on is the correct one and compatible for your hyundai accent model.
Ensure that the filter is on the right way, otherwise proper fuel flow could be obstruct.
Follow fuel line and check for any leaks.
Hope this helps.

Sounds to me like the fuel pump is worn out. They DO wear out. And even though they seem to be working, the brushes in the electric fuel pump may not be contacting all the commutator, thus making the pump weak. It may start the motor but can't maintain normal running pressure (27-35psi). Have you run the car out of gas shortly before this problem surfaced? If you have then it's your fuel pump. It was damaged when the tank ran dry. Even though the pump may seem to be working, it's still badly damaged and needs to be replaced.
Just as Matmenzies has stated, get a fuel pressure gauge and test the pressure. I'd start with a complete check of all your vacuum lines. Check for cracks on the vacuum hose that connects to fuel pressure regulator on the fuel rail. Also, if you can, get a hand operated vacuum pump to check the regulator. If you can place a vacuum on the regulator and it holds, I'd say move on the fuel pump and check it.
BTW, if the fuel filter has been changed, you may want to check to see if it was installed backwards! Some fuel filters are valved and will cause symptoms like this. However, this is an immediately noticeable mistake and you haven't provided enough info for me to say more. I'd pull it and check that it has any flow at all. You could have sucked in a big dirt ball and blown it right into the new filter, effectively stopping fuel flow. Then I'd blow out the fuel lines, just to be sure.
Start with these 2 things and post what you find. We'll go from there.

Here are the common cause of surges, cold stalls, 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.

Nicole 3 things keep a motor from starting.1. NO SPARK, 2. NO FUEL,. 3 ENGINE DAMAGE. Check to see if it has spark..
if it has spark its probably loss of fuel.. can be a clogged fuel filter or a inoperative fuel pump..
