Hard to start

Its hard to start my 94 Sedan Deville after it sets for a while. When I try to start it I have to turn it over 2 or 3 times before it finally starts, but once I have it running I can turn it off and start it right back up again. Its not a big problem seeing as how it does start, but I was wondering what could be causing this.

Check for a leaky fuel pressure regulator. It is on the fuel rail and has a rubber vacuum hose hooked to it. If you pull the hose off, and fuel drips out, chances are that it is leaking.
