No start issue Im a little frustrated

Just start with the basics. Turn the key on and see how much power your getting to the coil. I like to run mine at 8 but thats me. Next see how much your getting while someone cranks the motor over(should be close to 12). Don't over look the cap and the rotor. Carbon cracks are hard to see. Or better yet just check the spark while cranking from the coil itself if you have the right volts to the coil.
