What was the solution? I'm having the same issue and my car won't start if it does it just stalls I'm running the APR hpfp changed everything on the fuel system and still getting p310b
Sorry don't get notifications on the post... It was the HPFP. But my car started, it just lost power brutally just to get it right after, but always kept moving. I think you'll have to start capturing data with the OBD, etc. But if it just doesn't start not sure you can get much (?)
