...but I seem to be having trouble w/my Colorado starting. No forewarning when driving the day before...I get in this morning, turn the key...nothing at all. Then you hear the cd changer move and the clock comes on and the warning sound for the key being left in the ignition comes on, so I know it's not the battery. It is a 2004 LS standard w/45,000 miles on it.

Any suggestions?

Thank you for any help you can give me..
