My Kia Sephis keeps dying and wont start sometimes

That Engine fuse you are replacing is the engine fuse,The nearest ground that can short that out is the oxygen heater circuit of the catalytic convertor,it may be the oxygen sensor itself,but more than likely its the harness you will have to open the harness and inspect for a rub through wire

1999 Kia Sephia (1.8 Manual) ran fine when parked then next day wouldn't start. No spark, checked coils which were fine.

Sensors can fail at any time but they mostly fail at switch off. This is because some sensors have a habit of creating a voltage spike with the reverse polarity of normal when the power supply is removed. Normally, components are fitted to protect against damage from this but sometimes, even that is not enough.. The much higher voltage of a spike will destroy most semiconductors instantly and you only find out about this when the vehicle refuses to start.. Start with the fuse panel and electrically check every fuse first. Then go through and check related sensors like the cam angle and crank angle sensors. You may have to call in a professional. However, the loss of the timing signal may cause erratic running but the engine control has very little to do with spark so suspect the igniter modules and engine sensors first..

My 2000 kia sephia is not starting i bought a new battery, new fuel pump, new coils also wires and spark plugs, but still wont start. I also check the starter and took it to O' Railly Auto parts and...

sounds like either the teeth on the flywheel or on the starter itself are missing a few gears or the sylinoid is not ingaging the starter enough

My 2001 kia sephia wont start all the time. Just

when this happens you need to check somethings at that time to point you in the right direction, fuel press & spark , also you need to have the cam and crank sensors checked the shop should be able to find the resistance values of what they should be and then ohm yours. But the main thing is rule things out and narrow it down.
