Hi, one coil fires two plugs. So, if problem with coil,should be two dead cylinders. Maybe just a plug wire? Cylinders one and four fire together. 2&5--3&6, You get the picture. There could also be an issue with one of the ground circuits going to the coil pack. As far as the driver side tail lamp. The white wire with brown tracer carries the voltage, if no voltage, backtrack the circuit. There is a splice for that circuit S313, located at left rear quater panel, I'd have to look in order to locate.

Glad you got it going. If it had been a fuse, none of your tail lites would have worked. According to the MOD database. Databases are not always correct. Sorry, if I caused you any extra work. Have a good day.
