6.8l v10 sputter at startup

My 2010 f250 v10 is having an issue where at startup it sputters a bit. It just doesn’t start cleanly, you hit the key and it takes just a tick longer to start than it should and kinda sputters for 1-2 seconds then just runs fine. Sounds good, runs good. Any idea why it’s starting like this?


don't play well w others
Check for fuel pressure right at first crank. Sounds like check valve on fuel pump is leaking down
