Took the car to the local market today. All was fine, nothing sounded weird or was acting weird. Got the the market, shut the car off. Went into the market and bought some stuff and headed back out to get in my car. Tried to start the car and nothing.... no sound, nothing turned over, just dead, but the radio and all electronics came on.

I tried jumping it from the Trailblazer SS and nothing happened. Tried replacing the battery and nothing. So it isn't the battery.

What could it be???

 

Try your other key incase it has something to do with the theft deterent module.

Check circuit 5291 for a short to ground (STG) at the clutch pedal position switch connector as it might get shorted to the clutch bracket. If connector looks ok, then inspect the 10 amp emissions fuse in the Underhood Electrical Center to ensure it is properly seated.
(wiggle the wires by the clutch)
Also could be the clutch switch!!

 

is the lock light on the dash?



its going to most likely be something small like a starter relay or fuse

 

did you push the clutch far enough in?

not trying to sound like a dick but when i let my fiancee take my ss/sc to work, she did not push it in far enough and it did the same thing as yours.

 

Had the dealer tow me to them for warranty work.

Had a faulty clutch switch.

Heres what they wrote.
