what could kill coil pak on my ranger or is that possiable maybe a ground could dont know
coil went dead bought new one 4months later it went dead got another one but still got small miss don't know what is causeing it
Change the spark plugs and wires?
I agree with Tom, spark plug could be cracked or carbon traced, plug wire could have a hole in it causing the spark to go straight to ground.
Washing the engine is a big killer of coils. Moisture kills coils so keep it dry.
