Quote: OP make sure your source provides 12 volts to the petronix unit when hot. I had a car that ran well for a time, 30 minutes or so, then once things were good and heat soaked it died. When hot my source had less than 12 volts. Was fine cold.
I let the car sit overnight, tried it the next day, and still no spark. Should a volt tester on the + side of the coil give me voltage? Man I'm not good with this electrical stuff......
What is the air gap? If the air gap between the module and magnet sleeve is too great... The ignition will not fire...
With electronic ignition systems, when a problem arises many just start swapping parts when the basic components are fine.. This can also happen with a wide variance in temperature.
