It doesn't seem to me it is a routing problem. I think you have a spark plug wire leak instead.Replace wires.

Double check to make sure you didn't accidentally unplug and censors on the harness. Also check your fuses. for you ignition.

1997 Pontiac firing order is 165432

you will find the spark plugs it self by following the wiring thats going into the engine block if it a 6 cyclinder there is 6 wires change one spark plug one at a time DO NOT pull all the plugs out cause u will not remember the order they go inand thats the firing pattern if u lose the firing pattern u will have to call a mechanic or go online and look it up.
