Could be the plug itself or your distributor cap.
Low compression in a cylinder, a burnt valve, loose plug or plug wire, bad injector, bad electronics.
Depends on why it is missing. First thing is to replace the spark plugs and plug wires. If it is still missing then run a compression test.
you have backfire bacause you forgot to match wires with right cylinder
Yes it does have spark plugs....no it does not have wires, they have boots from cylinder 1-5 and a diff one for 6th cylinder
Did you also change spark plug wires ? It may also be a lose spark plug wire or coil pack...
Sensor??? A misfire is usually caused by spark plugs and wires. After that you change distributor cap(if equipped) , fuel injectors, check for proper compression.
Yes, if the spark plug wires can be connected to the distributor and works.
you might check the coilpak

The 2004 Trailblazer does not have plug wires. It has a coil pack per cylinder that connects direct to the spark plugs.
Under the spark plug wires in the cylinder head, on top of the engine.
If it has 4 spark plugs, then it's a 4 CYLINDER. ............4 plug wires, then it's a 4 CYLINDER
