6.8l v10 sputter at startup

[greatplainsturf]

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?

Check for fuel pressure right at first crank. Sounds like check valve on fuel pump is leaking down
