New Coil No spark

Okay try unplugging the connector circled in the following diagram. It is the magneto kill wire. If your engine should start you either need to run it out fuel, pull the plug wire, or choke it to death. It does run then you a problem in the kill circuit.

Yes as long as the ignitor is still plugged in.

Ok I finally had the chance to try your last advice on disconnecting that wire. Didn’t get a spark. Before I tried it I looked and the mower was definitely not engaged. But in case the pto thought it was I also tried unplugging it. Didn’t help either. Any other suggestions? Another man said I should check the shear pin , but I don’t think that it could be broken because it is not a direct drive being a front mower. And I don’t remember hitting anything with the mower that would have caused that. Could it still be a faulty coil? Any help you might have or suggestions would really be appreciated as I’m about to give up.
 
Even though you have the unitized PA420 the follow for the FC420V ignition should be the same resistance check for the ignition modules.

Oh I see the rest of the info didn't post. May be this is more your speed as it is more related to the problem.
