Reviving this old thread having this exact same problem, ruled it out that infact it was a bad ballast resistor by jumping the factory ballast (by pass) and she started BUT only about 5 sec. the napa ballast is glowing hot red! it is a 1.5 ohm.
Do i have a bad coil? maybe igniter?

2 days at your door step considering it came from the other side of the world.
