Check the coil, as that is where the spark comes from.
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.
Do you have C.O.P. ( coil on plug ) If so, under the coil.

No. 2005 is link and coil. 1990 is leaf spring.
This is how I diagnosed my 5.4 liter coil packs, I isolated the cylinder that was misfiring and then took a know coil from a good cylinder and swapped with the suspected bad coil. When the misfire went to the specific cylinder I swapped, I replaced that coil. Note- It is advised to replace all coil packs if you can afford too! Summit and Stylin has Hi performance coils for the fraction of cost as a single cost of the dealer's price.
They are under the coil packs. The coil packs are near the valve covers, and go into the intake manifold.
It does have a coil pack. Its where all the spark plug wires all connect to on the top of the engine near the drivers side firewall.
each spark plug has its own ignition coil on top of the plug, like many current cars.
How do I replace the heating coil in a 2006 Grand Caravan? I have no heat it only blows cold air.
On a 2005 Kia Sedona the coil packs are over the front 3 plugs. Wires go to the rear head.
It should be a yellowwire on the igniton coil
