If the car will not start...the spark-plug is bad.

ALL gasoline engines have spark plugs. Only diesels don't have spark plugs.

follow the plug wires they are on the heads
The 2005 Chevy Trailblazer has Coil-On-Plug ignition coils so there are 6 "coil packs". Each one is mounted on top of the spark plug.
That's the forward-most spark plug on the passenger side.
Depends on the size of your engine. IE if, you have a 6 cylinder (v-6) it requires 6 spark plugs etc.
