2002 1500HD fuel pressure/hard starting

I have a 2002 1500HD with the 6.0. It's really hard to start sometimes. This morning I checked the fuel pressure and it was at 0 before turning the key, when I turned the key it jumped to 30 and quickly fell to 0, did it again and the same. When it does start, the pressure is at 45.

Bad fuel pump check valve?
