My kia keeps dying! 2000 kia sephia. something is draining the battery new battery and alternator what can it be?

Look in the fuel pump/filter area?

It depends a/c or not any parts store will be able to tell you that

well if it is cranking its not starter or battery . maybe check to see if fuel pump is working .check fuses. you should be able to hear pump run for a few second . if pump working maybe fuel filter or sensor like throttle position ,air idle sensor. make sure all wires are hooked up on alternator & starter . no vacuum hoses off any where . is check engine light on ?

SOUND LIKE ALTERNATOR NOT CHARGING.CHECK FOR A LOOSE DRIVE BELT.IF DRIVE BELT GOOD AND ALTERNATOR FUSE GOOD AND WIRES NOT LOOSE AND DAMAGED PROBLEM IS FAULTY ALTERNATOR.

You might have a bigger electrical problem. One of your cables might be grounded this way allowing all flow of electricity to go to the chasis of the car, draining your battery. Check E.C.U. with mechanic

Good luck

If you have a volt meter turn on the car and read across positive and negative with volt meteryou should get something like 13.8 volts if your getting something like 12.5 alternator is not doing its job. also have battery tested.

i would take the belt off and then check the idler pulley assembly..it could be worn out..since the belt is off check the alternator pulley for any play also. A loose belt will not help the battery to keep a charge. if everything looks o.k. and you said you have a new battery and belt then it looks like your alternator went bad. Hope this helps.

I would check ignition items or fuel delivery if it just died on you. It wont be the battery unless it was dead and the alternator stop working.

make sure your battery good have it load test.to make sure you dont have a shorted cell.
