How does it start when cold?

While cranking, according to the mechanical gauge, I'm right at 30 psi. Yes, this was under hot engine no start condition. As to when it's cold; well it starts every time, first time. That includes a subsequent start after quite a few hours of sitting. Everything would have to be at ambient temperature. But... it always starts weak. Battery good, only a few months old. Not a cheap battery either. Anyway, that's what lead me to troubleshooting the fuel system.
