2005 Kia Sedona Q&A

2005 Kia Sedona Question: Why does engine stall intermittently while ideling or driving?

The Sedona has 107k miles on it. It started doing this last September. I was leaving work, coasting to a stop sign, and it just quit. I turned the key and it started right up. I drove about 4 miles and while sitting at a red light it stalled again, but I was able to restart. Then, the next day, while driving down the high way on a 400 mile trip, it stalled and restarted on its own at 70 mph 3 or 4 different times. But, the latest occurance left me and my family stranded 100 miles from home in freezing temperatures and wouldn't restart until the two truck dropped it off. However, I'm now fearful to ever drive it anywhere. I've had people mention the fuel pump and others say a crankshaft position sensor. Please help! Thanks. -
Answer 1
never wait to find out reasons for this kind of issue. they never get better by themselves and always leave you stranded when you need it the most. i would check the fuel pressure. it could be a failing fuel pump. check for any codes that may identify a failing system. check the big air intake hose from the air filter to throttle body for any cracks or holes.

This is sound like the fuel pump relay going bad. Sedonas has this problem. If the crankshaft position sensor start going bad usually car wont start. Once is start up engine will run until next start. Bad fuel pump would not start right away .Is not it? -
