2006 Sedona not starting - Kia Forum

Driving that long. Could be many things. Do have the codes read. History codes. First thoughts are, dirty throttle body and IAC motor, fuel pressure, and no air flow threw the engine. (converters)

Have them test the battery and double check the connections on the alternator.
Possible the battery suffered some damage from the bad alternator.

I'd say you have a crankshaft sensor problem.

Sounds like the same problem I have been having with my 2002
Sedona for the past 6 or 8 months. It would run OK for several days,
weeks, or months, then just quit. If I let it set for 10 to 20 minutes, it
would restart and run fine for at least the rest of that day. About 2
weeks ago, I was fortunate that it happened when someone was
with me, so I was able to determine that it was not getting any spark.
Since then the problem has gotten worse and more frequent - it was
happening almost every day and would take over 1/2 an hour before it
would start again. This morning was the last straw. I drove for about 4
miles and it quit. Took 1 hour and 10 minutes before it would restart.
Drove another 2 miles and did it again. This time it took 1 hour 35
minutes before restart. After 1 more mile, it quit again. Took 2 hours,
this time. Made it another mile and BAM! - did it again. My bro towed
me home. I determined that it is most likely NOT the crankshaft
position sensor, because 99% of the time they either work, or they
don't. Very rarely does it cause in intermittant problem. The most
likely suspect is the engine computer. That was always a likely
culpret when I worked on GM cars. Today I installed a $50 junk yard
engine control computer.
I am crossing my fingers!
I will know on Thursday, as I have a 50 mile trip to make.
I will post again on Thursday, to let you all know.

check under the hood , on the drivers side for a black box , that contains fuses & relays, check these out.

Its probably a fuel problem i would start with the fuel filter thats the easiest part to rule out first. The best thing to do is hook up a fuel pressure gage to the check valve on your fuel rail to see if you are loseing fuel pressure. If you can not do that you can just start with the fuel filter see if that solves your problem.

2004 kia shuts down after driving a mile or two want crank up until it sits a few hours solution is crank sensors there are two of them...

Tranny problems. It could have seized up and thats why it won't start.

Turn key to on position and listen for fuel pump to turn on, if not check fuel pump fuse and relay. May also be crankshaft sensor. Maybe not getting any spark.
