Usually the first thing that I would check is a bad ground of the coil itself. Now if that does not work then you should let a professional do this but it is an old trick, but power up the coil manually by grounding the bottom of it to the car and then taking a wire from the pos side of the battery touch the batt post of the cap. You olny need to do this for a second. Then take the wire away from the battery and DO NOT TOUCH THE CENTER OF THE CAP!!!! but ground out the top of the cap. YOU WILL SEE A SPARK!!! if you do not then more than likely the cap is breaking down and not holding a charge. A coil not sparking could be many things like a ignition module it could be the crankshaft possition sensor or camshaft position sensor
Bad coil or coil pack.
I would suspect the coil itself, even with the wire connecting to the distributor cap removed, you should still see a spark from the connector on the coil to the body of the coil itself
I have replaced the coil and distributor cap.
No spark would usually be the ignition coil.
The coil to the spark plug is called an ignition coil on a Yamaha EF600. It is also referred to as the spark coil. These two terms are used for any coil to the spark plug in a vehicle.
No. The coil provides the spark and the module tells the coil when to spark.
The purpose of a coil pack is to supply the spark to the spark plugs.
You apply 12 volts to the coil primary and then release it . The electricity will go through the secondary coil and spark the spark pug.
coil kaput buy new
Could be a bad ignition coil either traditional type or C.O.P. (Coil on Plug) type
Do you have spark at the coil? If not it could be the coil but I would put my money on a faulty ecm. Happened to mine and the repaired ecm fixed it.
A coil is what gives you spark it distributes the power to your spark plugs so it would run bad or not at all check for spark. The coil produces the power for the spark to ignite the fuel/ air mixture in the combustion chamber of the engine . The distributor systematically distributes or places that spark to the spark plugs in the firing order .
