Depending on what diagnostic trouble codes your vehicle has when a technician checks it with a scan tool, your Trailblazer may have a bad Accelerator Pedal Position sensor (APP), a problem at the throttle body, even a very dirty throttle body.

Since you can’t get the car started, I’d suggest enlisting a qualified mobile mechanic who can come service the car at your own convenience.
