You might also check the VSV (vacuum switching valve) on the back of the valve cover that runs to the fuel pressure regulator. One "theory" I heard for its function is to help with hot starts, by upping the fuel pressure while starting. Not sure I believe that theory, but it was from a fairly reliable source. I actually have mine disconnected (bypassed) and starting doesn't seem to be affected and the engine accelerates a bit smoother.
