The very FIRST thing that I would have you do is read the DTCs. There are THREE fuses for the coil power. Two for the drivers side and Two for the passengers side.
Under Hood Fuse box, Fuses 16, 18 & 22.
Fuse 16 is common for all the coils and fuse 18 is for the even number cylinders on the passengers side. Fuse 22 is for the drivers side.
Take a look at the fuses and make sure that you read the voltage at the fuse to make sure its getting power. Measure the test slots on top of the fuse to chassis ground.

First off it's a good idea to put your cars info in your profile...helps us to help you !!...there are 2 separate ground wires that connect to the back of the cylinder head (pictured) and each one supplies the ground for the left and right bank....it's pretty difficult to get to so you might be able to see them with an inspection mirror...take a look !!...if it looks OK I would disconnect C109 (big connector by the EVAP service port) and with a test light connected to battery positive probe the BLACK/WHITE wire...that will check for a good ground between the connector and the back of the cylinder head...I prefer using an old headlight bulb that draws 3 AMPS or so...that really loads the ground circuit but you can check it with a test light...if it doesn't light you have a bad ground or open between the connector and the back of the cylinder head...if you have an issue that is where you may find it...if the test light lights you would check to see if you have an open between S101 and C109...on the POWER side I'd see if you have battery voltage at the PINK wire at C109 again key ON...feeds power to ALL the coils !!...this wiring is based on a 2001 !!
