I read the other starting problems and didn't come across mine so I hope someone can help. My Saturn runs perfectly fin but when I go to start it in the morning (it's not cold out, maybe 85 outside) it is very hard to start. The engine cranks fine. After it's started, I can go to a store and when I come out it starts fine. It's only after it sits for awhile.

Also, it was fine 2 weeks ago and it's been slowly getting worse.

I would start by removing and cleaning the throttle body. Making sure the IAC valve passage is clear.
Also, check to see if fuel pressure is bleeding off. If so, the fuel pump module in the tank will probably need to be replaced. It has a check valve in it that can allow fuel pressure to bleed off over night. Assuming there are no fuel leaks.
Try turning the key to run and leaving it there for a few seconds before cranking. You should be able to hear the hum of the fuel pump for a few seconds. If it starts easier after doing this, it sounds like fuel pressure is bleeding off.
