99 Deville trouble starting in the mornings.

I have a 99 Deville w/ 95K. The past few mornings I have had a great deal of trouble starting it up. It takes about 15 minutes for it to finally crank up. Funny thing is that once it's started, no problems the rest of the day. It starts on the first try for the entire day. The next morning. Same thing. I had one "Check Gas Cap" reading a few days ago but none since. I live in the South so cold weather isn't an issue.

Any clues as to where I should start?

Thanks in advance for your help!

Humm the fuel pump circuit on you car goes through the oil pressure sending unit. How is the oil level and how long since it has been changed? Let me know

The oil was changed about two monts ago (1500 miles or so). My gauge is reading "oil life left 73%.

You really need to have the fuel pressure check when it is cold --- I suspect a bad fuel pump.
