Although it's unlikely the switch. The inertia switch kills the fuel pump, so the car will try to start, but it won't turn over.
Do you have an alarm/immobilizer on the car. That could also prevent the car from even attempting to start. Not sure if your MY requires a chipped key.

Do not tighten the positive battery cable on the battery too tight
Fuse # 12 / 10 amp right engine bay fuse box , The # 1 fuse is on the same row and closest to the fuse box battery cable terminal post
This fuse relies on the right engine bay fuse box relay to close ( referred to as one of two ignition positive relay ) and can be swapped with the left engine bay fuse box relay ( which in reality only runs your horn )
Fuse # 3 / 25 amp left engine bay fuse box , this fuse is hot at all times
The specific starter circuit does go through the inertia switch ( reference point 7 stop sign double hash page 38 of the 1997 wiring guide ) as well as other circuits and the switch is fickle from reading and can be jumpered with a paper clip at the switch connector between the only 2 white wires
Starter solenoid relay large left # 4 allows power from the battery coble to flow through the starter motor after it extends the starter into the engine flywheel
The solenoid itself is attached to the starter in a way it won't come off without removing the starter so we hold off on that
By feeling for the relay to click closed or not splits your problem in half
You have inhibits like the gear shift lever position switch ( referred to as linier switch ) and the key chip in your key as it should have a lump in it , and a couple of other inhibits
You have a ZF4HP22 transmission which is different then the usual ZF4HP24 on the transmission itself position inhibit , it does not have a rotary switch attached to the transmission body like the ZF4HP24
But the relay clicking every time wanted is the starting point
If it does not click swap the relay with a headlight , fog , or A / C clutch relay , The base unhooks and you can flip the base over to spray some penetrating oil to free them up
