2002 Dodge Ram Power to one bak of plugs

I have a 4.7L engine. Just blew a radiator and it over heated. Replaced radiator and now the left bank (2,4,6 &8) cylinders have no power. The right side is working as it should. I removered each plug coil to determine. Nothing happens on the left bank. Is there a fuse for the coils? Looking in the fuse box, all appears to be ok. I am retired and if I can repair this without the dealer expense, great! I have since found my code reader and have PO354 which is Ignition Coil E Primary/Secondary Circuit Malfunction. Can anyone help?
Thank You
