Long cold cranking
Vehicle is a 2002 Chevy suburban, about 140K miles on it. I am having problems with long cranking times especially after its been parked for an hour on longer. I've already changed the fuel pressure regulator, and still have the same problem. I'm starting to lean towards a fuel pump problem. Anyone have any ideas?

Welcome to the forum.
It's probably best to check the fuel pressure before embarking on a major job like that. The fuel pressure should be 55-62 psi with key on, engine off. If it started low and only gradually built up, perhaps the fuel filter could be clogged or fuel pump could be on its last leg.
