Briggs twin engine. and you have no spark? Remove the kill wire between the two coils and see if it has spark.
580447-0116-E2 Briggs, Scag puts and oil pressure switch that can kill spark, have you checked t?
Three cylinder engine and three separate coils, and no spark to any . I see no mention of the pickup trigger coil?
If you test the trigger coil with voltmeter on low voltage, do you get any kind of reading from it?
Looking a the wring schematic, I don't see anything else, after you checked the oil pressure switch.
I would expect it to have a pulsating signal as engine was cranked.
Just test the two wires from the sensor, and if you get signal, it should work. don't have wires attached , just loose for test.
Then it would seem to be good and working.
Good trigger, new coils, new igniter, still no spark, and oil pressure switch is not grounding spark.??
OK> I don't know anything else to try!
I don't have manual for this engine. I don't know if it should have power to both sides, seems like it would not, but I don't know. Let me se what I can find.
See section 11 for the ignition system. Seems straight forward.
