Lots of people turn their key to the "on" position before actually cranking their car or truck. They count to 5 or 10 and sometimes they can hear the fuel pump working, pressurizing the system. Then the car usually cranks the first try.
The theory is that the fuel pressure fades overnight. I usually do this on my non-GM cars in the morning, but don't bother the rest of the day.
I don't know what normal "fade" is, but a fuel leakdown test might pinpoint where your problem is, especially if this trick is needed more frequently than once a day.

Please let us know if changing out the ignition switch fixes you up.

I want to add....by NOT FIXING the problem...for the time being, you have a good anti-theft device! (However, it could get worse, then NEVER start if NOT fixed??)
I have an isuzu truck..after it warms up, when you try to start it a 2nd time, it'll start, but will stall almost immediately UNLESS, you simply turn the key "off' then "on' very quickly.
This whole problem started when mice ate the air filter and a piece of air filter paper got lodged in the Mass Air flow (MAF) sensor. i cleaned the sensor, and the truck has had this starting issue ever since. I figured out the "fix', purely by accident!! I won't try to fix it permanently, as my truck is full of irreplaceable tools and i cannot afford to have it stolen!.

#289 of 301 Jimmy [jsimmes] TEMP SENSOR switch

Jimmy, There is a engine temperature sensor switch on the engine block between the #1 and #2 spark plug (driver side). Two wires, remove the wires and if vehicle starts everytime replace sensor $25 to $35. Do not leave wires pulled off, if you do it will waste a lot of gas. Depending on temperature of engine this sensor send a signal to computer and computer send gas to the intake. Hope this helps.
