2002 sonata 2.4 it will strat n run 7 to 10 seconds and die

Asked by Sep 03, 2013 at 11:46 AM about the 2002 Hyundai Sonata FWD

Question type: General

1 Answer

get a NEW battery....five years old as old as they can get because they will not accept a charge ten percent per year with these new tin/antimony alloy batteries [no lead anymore] and when you do insure a three hundred amp connection by wirebrushing the lug and the spot on the chassis/ground where it attaches...your ECU is getting starved of reliable POWER....new battery, clean with wirebrush...problem solved~
