Unhappy 2003 Kia Sedona wont start

Hello everyone, this one really has me scratching my head.

I have a 2003 Kia Sedona that starts and runs fine but after a short drive of say 5 minutes wont even turn over. The car has never cut off on me and I don't have a 'check engine' light. I tried jump starting no joy. I put a volt meter on both the car's battery terminals and the battery's post and read 12VDC (no voltage drop there). When my bud turns the key, volt reading drops to 11VDC but no crank. One thing I noticed is that although the volt reading stays constant and strong, the headlights and radio will cut off as I'm trying to start it. I let it sit for a couple of hours it started right up.

This is the second time in three days that this has happened and it only seems to happen on short trips. I've read through a bunch of 'no start' threads but none of them sound quite like this.

Welcome to the KIA forums. Take off the battery terminals and give them a good clean also check connections at starter and chassis earth. I think your battery is probably not recharging as it should, possibly due to bad connection at the terminals. Fully charged a good battery will usually have around 12.5 -12.6 volts with no load. After starting the car and only a short drive your battery has not recharged enough to restart the engine. Might be also an idea to get your battery tested under load to check it's condition. I see you are from a cold area so that definitely doesn't help if the battery is getting a bit weak.

TAKE YOUR TIME, THINK IT OUT, DO IT RIGHT, DO IT ONCE!! original quote by me as far as I know. :rolleyes:

Sorry for the delay getting back, but I just got back in town. Here's what I've found out. The battery cables are clean as are the connections on the starter. I pulled the starter and took it to two different national chain auto parts stores and had it tested. Started tests good. Found some diagram info online and ohm'd out all the positive and ground wiring, relays and fuses. Everything looks good. Put the car back together and it worked like a charm so it looked like I had a bad connection somewhere that I fixed with my troubleshooting. Until about three days later when the 'no start' came back in exactly the same way. I figured I had to be missing something so I started over with the starter. This time I took it to a auto electric specialist and had it bench checked. It tested fine. I explained the problem and asked if they could test it again. After five test cycles, it finally failed. Three failed cycles later, it was working again. WOW!!! The final fix was to replace the starter that appeared on multiple occasions to be working fine. That was on 1/30 and although I have driven it in the last two weeks, its been fine.

Thanks a bunch for the help
