Newbee needs help with ms461

[TinaRose3825]

Hi, I'm having trouble getting my Stihl 461 to start. I replaced the carborator, filter and lines as well as the spark plug. I was getting spark before but not every time. So I figured I had a short in the wires somewhere. So when I took it apart to replace the impulse line I would also trace the ignition wires. Well, I don't get spark at all now.....I have plugged all (2) wires back to the right plugs snuggly and still nothing.
Is there a trick of the trade ya'll can give me to test something else......idk
I'm very open to all info./learning

Thank you all in advance

Sounds like you are not afraid to throw money at that saw so you might as well replace the coil. Going by the reported "not always getting spark" symptom that might have been the best place to start.

Also check that you don't have the ignition grounding out the coil.... I've done that once or twice while diagnosing a saw lol

This might help

May be a broken wire inside the insulation that is not apparent. It may test ok initially but not if wiggled around…
a new harness is cheap…cheaper if you make your own.

Remove the switch wire from the coil and try it. If no spark and the plug wire is good, then get a new module.

is the coil tight and spaced right- had a 390 xp come in a couple of weeks ago with loose coil bolts- don't know why it even sparked sometimes..
