RE: starting issues
you can do one very simple check on the regulator by pulling off the vacuum hose, if there is fuel in the hose, the regulator is bad. If it is dry you will need a fuel pressure gauge to find out if it is bad. With the gauge connected your fuel pressure shopuld be about 55-60 psi, running. if you remove the vacuum hose with the gauge connected and the engine running fuel pressure should climb, applying vacuum with a vacuum pump to the regulator should make pressure drop. If pressures are doing what they are supposed to, I would look somewhere else. I have found several regulators leaking on the 99 and up trucks as well as 00 and up utilities.
