Smile After sitting overnight (or more than 7 or 8 hours), my 1997 Yukon won't start.

1997 Yukon doesn't start after sitting over 7 hours - HELP! After sitting over night my Yukon won't start. The only way it will start is by spraying starter fluid in the carborator. Once it's started in the morning, it starts great all day long. After it sits more than 7 or 8 hours (usually overnight),I have to get the starter fluid out again. Today it started hesitating and felt like it was going to stall a few times but started great after the initial spray of starter fluid in the early am. ANY HELP WOULD BE APPRECIATED!!

First..DO NOT spray starting fluids into these engines!

Sounds like fuel pressure is getting low.

Fuel Pressure checks out perfect. I've been told not to use the starter fluid but when I have to be at work at a certain time and it's the only thing that will get it running, I don't have much of a choice. I've decided to bring it to a GMC dealer this week, much as I don't really have the $ to do so. Since none of the mechanics can pinpoint it, I guess it's the only way to go at this time.
