I'm surprised that ScottD hasn't ChimedIn yet suggesting that you
should have a NoidLight so as to be able to check for a signal on the
InjectorWires. Is there possibly some sort of inductive pickup sensor
that you can get for your Fluke that might provided the needed info ~
probably expensive if it exists ~
