How do i diagnose whats wrong with a coil pack on a 2000 pontiac sunfire?
First up, get a Haynes or Chilton REPAIR MANUAL specific to that Vehicle.
Such purchase will be a addition to this and other automotive sites.
Disconnect any or all spark wires and if in a garage, crank engine to verify spark.
If no spark then it's probably the Coil.
Coils either work or do not. There is no middle ground.
Try changing the Coil as a last ditch effort.
If there is spark, try changing the fuel filter as it seems to be a fuel deficiency.
Try changing the Spark Plugs.
Try changing the Spark Wires.
Maybe the Fuel Injectors are electrically faulty.
