What's up with a fuel rail pressure malfunction?

Asked by CBT Jul 21, 2014 at 08:12 PM about the 2012 Kia Optima EX Turbo

Question type: Maintenance & Repair

I have a 2012 Optima. It has 40K miles. When I started it the other day, it turned over several times before it started. Then it bogged down while driving, like the fuel wasn't flowing properly. It was worse the next day. When I get on the highway, it seems to sort itself out for the most part. Took it for a diagnostic and it is a "fuel rail pressure malfunction, pressure too low". Any idea how I determine what is causing this?
