Cylinder 5 coilpack issue

[tom268]

Hi guys, 

 

So I've had the P0300 code come up which has led me to check all the plugs and coil packs. Coil pack 5 isn't sparking, is this a sign that I need a new coil pack or is this a sign that the electrical feed to the area is dodgy? (I assumed all coil packs on one side shared a supply/ cables? 

 

For info: All spark plugs were changed 4000 miles ago and the car has had no problems until now. Problems started when it was very wet. Eml came on and threw codes on for passenger cat below threshold and both o2 sensors in the rear of the exhaust. 

 

Possible water damage somewhere? 

 

Many thanks, 

 

Tom

Swap the coil pack to another cylinder and see if the fault follows.
