I kind of thought the samething and i will look at the wiring closer. What gets me is that all 4 coils have no power coming to them if 1 or 2 i would be like ok but all 4 makes me think pcm, i need to find out what type of obd2 to usb programming wire i need so i can hook it up to the laptop and to the obd2 and try to flash the used pcm... btw thank you so much for replying.

Try cleaning the ground connections on firewall , believe there are a couple places that can get corroded,,cant help with flashing pcm as I too thought it took expensive software , but when I replaced my pcm I got one off ebay and they programmed it to my vin and it wasn't to expensive around $150 programmed an lifetime warranty

Still Nothing found
I tried to look for broken/damaged/corroded/pinched wires to no avail. All fuses underneath the hood look good. Thanks everyone
Ok I was able to check the coil wiring and traced it back to the plug.
So I was able to get my heavyweight body near the brown and white wire the two on the very end one has power and the other does not before the plug. Does that mean PCM not send power to that side of the bank? Well one of the 2 brown/white wires have ground.

I removed the pcm connectors and feed pos feed thru 2 injector wires and 2 coil wires back to the pcm connector and checked with a test light and i get power on the other end. I believe that the wiring going from each of them back to the pcm is fine. where do you think it might be broken? Thank you for all the help. or any idea where i should start? is my best bet just unplugging the harness and and checking each wire or should i be looking for a specific colored wire? Once again thank you.
