Mouse chewed on right side center coil replaced coil and connector, but still wontfire on right bank
Mouse chewed on the wires on the middle coil of the right side. The green wire shows that I have power, but the entire bank wont fire. I changed the middle coil and wire, but still have no spark to the right side bank.

Re: Mouse chewed on right side center coil replaced coil...
Sounds like the trigger to activate the on/off function of the coil is missing.Having power at the coil is good but to activate the coils build up/collapse you have to have a signal to tell it when to.You will have to back probe the trigger wire to find out where its been chewed with a continuity tester with noise.The noise option,multi meters,is very good if your doing a bit of testing on your own and tells you that cicuit is intact with out having to read multi meter screen.Good luck with it

Firing order is 1-6-5-4-3-2.
Cylinder locations: left front bank-1-3-5, right rear bank:2-4-6.
Coil pack on front left side of engine: front coil: #1 to passenger side, #4 to driver's side of coil. Middle coil: #5 on passenger side, #2 on driver's side of coil. Rear coil: #3 on passenger side of coil, #6 on driver's side of coil.
Ouch! A case of the raucous rodent! I've been there...Not fun trying to track down and repair all the damage.
First of all, let me explain how the code sets: The computer monitors the PRIMARY side of the coil to determine the burn time on the SECONDARY side of the coil. This can be a little confusing. The code will set when the computer determines that secondary ionization (burn time) was too short, too long, or did not occur at all.
If you have confirmed that there is no spark at the spark plug wires, then that is why the code is setting...ionization is not occurring at all. What can be a little confusing is that this can be caused by a failure in the PRIMARY coil circuit even though the code is indicating that the computer is having a problem with the SECONDARY circuit. (The secondary circuit can malfunction even though the primary side is functioning perfectly, but if the primary side malfunctions, the secondary side ALSO malfunctions - it is impossible for the secondary side to work if the primary side is not working.)
So, I said all that to tell you this: I think you have pretty much eliminated the entire secondary side of the ignition by replacing the whole circuit. So the problem must be on the primary side. (Probably more chewed wires)
There are 4 wires going to your ignition coil. The BROWN/WHITE wire comes from the ASD RElay and supplies battery voltage to the coil assembly. Since the other four cylinders are firing, This wire has to be OK.
The code you are getting is for coil #2. This coil is controlled by computer through the DARK BLUE/TAN wire. If you disconnect your coil connector and probe this wire with a test light connected to the POSITIVE battery post, it should "blink" when to crank the engine over. My guess is that it will not be blinking. You can do this also on the BROWN/ORANGE (coil #1) wire and the DARK BLUE/DARK GREEN (coil #3) wire to see the difference.
Anyway, if the DARK BLUE/TAN wire does not blink, then the wire is broken (chewed?) between the coil and the PCM.
Well you need to check the harness to see if it is getting power. You may need to take the plentum off and then unplug the harness and then reinstall the plentum but make sure that you leave the harness out so you have access to it.
Then you can make a test light or purchase one. Plug the test light into the harness and start the car. This light should flicker, if not you didn't repair the wire properly. Doesn't sound like a fuse being that none of the injectors would work if a fuse blew.
It could also be that the PCM grounded out when the mouse chewed the wire and needs to be replaced.
Don't worry about checking the ASD Relay because that would cut off all power to the injectors and coils.
i think you might have a mouse living in your engine compartment
but i would look at a mouse dead inside your muffler since this is the warmest place the cuts off the cars way of breathing
when you come to a stop the dead mouse moves inside muffler and creates a blockage just enough to almost smother vehicle rats find muffler pipes warm area to live in
i would also change the oxygen sensor out too
since you mentioned rats i would gothrew whole vehicle in detail and look for chewed frayed wires windshield wiper motors things of this nature they may have chewed threw a relay and you wouldnt know once you have rats they can do lots of damage to a vehicle
also if vehicle sat for long time i would check the tank for debry and change the sending units filter out for better performance along with vehicles fuel filters
fuel injector relay can also be bad giving you the chug
build of gunk in the throttle body houseing
air filter clog or not enough air
these are things i can think off the top of my head since im not there in person to see vehicle
i hope this had helped you in some remedy
