my 2001 kia sephia after around 20/30 KM starting jugging in another word cutting fuel and not moved. then i'll have to turn-off the engine and restart again and it will give me another 5 or 7 KM drive & start the same problem again..again i turn-off the engine & restart will give me the same distance & same shit happend.
i have changed the the plugs & cleaning the injectors, replacing new fuel filter but still not good..i experienced that when engine got heat starting this kind of problem....any ideas i'll appreciate

Regards,
Cooldin

Try replacing{ swap with similar relay} fuel pump relay it sounds like something electrical[ like relay] might heat up and cut out. Once cooled down goes ok until heated again.

Thank you Mr Pulsar86.. however, i noticed that the fuel pump relay is not there.
I checked the fuse box cover showing some fuses & relays including the fuel pump relay in brakets, example (51) others not. so i don't know what does that mean?
I was driving the car for a long time without that relay, and just now this kind f problem started.

thanks once again.

If it has an electric pump it should have a relay somewhere, maybe a previous owner has messed around with how the pump is wired. Probably best to get an autoelectrician to have a look and see what has been done wiring wise and get the fuel pump checked over just incase it is the problem. Keep us all updated, I used to work restoring old cars and some wiring gets altered by owners over the years, not always for the better and then causes problems later on..

Good at least you are running ok. But if I were you I would still get the fuel delivery system and wiring etc checked out or it might start misbehaving again after a while.

go to a junkyard, get a relay, and put a fuel pump relay in there!
