This is done at the ignition coil.
Please read my response on how to test it. You need a test light and a second person to help.
This was my response.
Okay, check the white/black wire at the ignition. Turn the key to on and test to see if the light comes on.
If it does, go to the other side and the light should on as well. Then have someone crank the engine and the test light should flash while cranking.
