Nelson, check fuel pressure regulator and fuel lines.  Look for leaks(both vacuum line to the regulator and fuel lines).

Do you have a fuel pressure gauge?

If so, when its cold and left overnite, have someone try to start it and you watch the fuel pressure guage.  It should shoot up to your operating pressure(40 or so) really quickly.  It should also stay there for a while after you shut it off.
