Did you check for primary voltage at ignition coil? How long since a tune-up? Any applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader. Your local autostore should have one.

Just to add, the pink wire at the coil is primary voltage, goes hot with the key on. That is a fused circuit, ecm 1 fuse--20 amp under the hood fuse box.
