Question about 2007 Chevrolet Colorado (Extended Cab) New Cars
I have been told that the problem with my 2007 Chevrolet Colorado is the security passload sensor. The engine will turn over, but will not crank. I wait for about 10 minutes and try again, it will start then. The check engine light does not come on.
I have an 07 colorado and had this very same problem. Ocassionally i would hop in the truck and stick my key in...it would turn over but not crank. I read numerous threads that is was my crankshaft position sensor....like you i would wait ten minute and it would crank right up. After i replaced the sensor, 2 weeks later it did it again. Read more threads...got a brand new key and took off all of my keys to reduce weight on the ignition cylinder. 2 weeks later it did it again. Finally I figured out that all of those threads were wrong. My passlock light was flashing during those 10 minutes of waiting for one reason!!! My positive battery cable had corrosion on it. Even a little corrosion on your terminal will trick the passlock sensor into thinking the truck is being hacked and will not crank. Take it from me, clean the **** out of your terminal wire the proper wire brush and neutralizer, then coat the terminal and cable connection with a pile of either bearing grease or diode (red) grease to help prevent future corrosion. 4 months later i still havent had the problem come back, and I had it happen over 6 times in two months. Try it and see.

Your truck has what is called VATS Key or vehicle anti theft system. There is a small chip that is in your key. This chip has a set resistance that the computer measures. If there is moisture on the key, it can cause this, but the problem is likely either in the tumbler switch, or with the key. If you do not want to take it to the dealer for the repair, you can actually buy a kit online to bypass the VATS key module. (it will come w/ instructions.) If you have another key, try it to see if it has the same problem. If not, then it's the key. If so, the problem is either in the tumbler switch or the VATS module.

That means there is a problem with the VATS System. This sometimes happens when the battery is disconnected for an extended period. You might need to do a relearn for the keys. You can get it done with the right scanner in 5 minutes, but there is a way to do it without one.
Turn the key to the start position, release it to the on position, then leave it on for 11 minutes, then turn it off. Repeat this sequence three times, and on the fourth try it should start if that was the problem.
