i am facing this oso,
my car kenot start, not even the alarm oso nothing,
no light no nothing, totally dead,

got fuel, battery got power, no banjir no kena water.

the simple answer are, "the master fuel rosak"
you need replace it, cost maybe rm10, but
if got towing the foreman will tarok you change oso battery
cost n this n tat maybe will up till 400rm.

try look at near battery or near fuel box for the master fuel.
use wayar to temporary connect it.
