Hey Guys,

I've got an '03 CTS that won't start. 3 weeks ago I went to get in my car after driving it 2 hrs before and it wouldn't start. The battery is fine. The car is cranking good but won't start. I tried for a few minutes and then gave up. I went out about an hour later and the car started without any problems. It has started great ever since until this past weekend. I had gone into a store and came back about 30 mins later and the same thing happened. After about 30 mins it started right up. Then again the next day but this time it wouldn't start at all. I had to let it sit overnight before it started again. I'm stumped! While the car is running it runs great. No hesitation or stalling. I do have a P0128 engine code that I have had for about a month. It is for the thermostat not getting to the proper temp. I think these things are not related. Please help. Thanks.
