Hello my name is ***** ***** am I speaking with?
Which engine are you working on?
Hello. My name is Tan.
Do you have 12 volts to the red or purple coming from key switch to the ignition module? If yes then check voltage on that wire while cranking what is your voltage reading?
If you have voltage to the red or purple wire above 9.5 volts when cranking we will need a peak reading volt meter to test for peak volts to the coil blue wire when cranking. We will also need a spark gap tester connected to the ignition coil for testing spark quality.
Ok we have to do these tests to find the problem.
Post back when you get the time to do these checks.
Your welcome......Talk later.
