Spark

Wondering if coil needs to be mounted and
grounded to work? I checking nee coil, but old v
Coil still mounted cause screws are stripped. So
wonding if nee voild needs to be mounted to work.
If not, then the nee coil not sparking.. So i would
guess crank sensor, right? Is there a way to bypass
crank sensor, like crossing wires or something...
Just asking.
