Good morning.

I would suspect the wire harness. inspect the harness carefully for any rodent damage. you need battery power to the coil and the other wire goes back to the PCM. make sure you have voltage to all the coils that are not working.

I attached a wire diagram for you to view so you can see the color wires you need to check.
