Hi, Im Tech Michael,
Make sure you have good connections between the battery and the coil.
You will need a meter for this. It could be the ignition switch but more than likely this will be a bad relay or wire or connection from the relay to the Ignition. ALso make sure you have a good ground or you will get the exact same results;-)
But I would first suspect the relay contacts have worn or become contaminated as they will over time.
In any case, I will stick with you until this is complete.
Please rate kindly thus far, it won't cost you anything to rate my service to you kindly,
you won't lose me by rating;-)
It actually will keep us locked in until this is working as it should.
Then you can reach me by simply replying to this message anytime;-)
Thank you and have a wonderful day!
