The 2004 Trailblazer does not have plug wires. It has a coil pack per cylinder that connects direct to the spark plugs.
The 2004 Saturn Ion does not have traditional spark plug wires, as it uses a coil-on-plug ignition system. In this system, each cylinder has its own ignition coil directly mounted on top of the spark plug, eliminating the need for spark plug wires. This design helps improve reliability and reduces maintenance needs.

Yes , its EDIS ( Electronic Distributorless Ignition System ) so it should have spark plug wires ( I believe in 2000 the 4.6 L went to Coil On Plug - C.O.P. )
No.
Remove the spark plug wires from the spark plugs, use an extension for your Allen wrench, and use a spark plug socket to remove the spark plug.
