97 dodge 2500 van 318 engine. No spark

I have a 1997 dodge van with a 318 engine that won't start. I have changed the cap and rotor, and spark plugs. I pulled the plug on the primary of the coil and
checked for voltage with the ignition on. The voltage goes up to 14 volts and
instantly drops out. Can anyone tell me where the source of the primary voltage
comes from, or what controls the voltage. pcm?

I am not sure what caused the loss of primary voltage, but I changed the
coil and it works. So problem solved Thanks
