I picked up an 18 vanguard engine for my zero turn First thing I checked was spark only to find none. Then I cleaned the flywheel and coils also regapped at .010. Once again no spark. So a friend had a spare parts engine ( 16HP) so I borrowed his coils. Once again no spark. Then I said forget the cheap way. I ordered new after market ones on the internet. (being cheap is a habit with me) I installed the new coils only to find no spark. You would think I would give up by now, but no I found another parts engine that has spark before I removed them Now I figure if I take both coils and the flywheel, which to me I believe is the whole ignition system it has to work. Guess what it doesnt> I just don't believe I could have 8 bad coils and 2 bad flywheels. Can someone help?? Mod 350442 Spec 0043-01

I feel for you. I think you need to chase down the safety switches. If they aren't happy then a 1,0000 IGN Coils aren't going to work. Check safety switches and temporally jump them to let the Ign coil do Its job.

If all the safety devices are engaged and the equipment still will not start, there might be a problem in the wiring or the switches/modules have gone bad.

8. Ground (stop) wire is grounded. Check to see if the stop wire has rubbed against the flywheel.

If there is still a problem get back.

Im sorry I failed to say I didn't install the engine Its sitting on my bench and there are no kill wires hook up to the coils

I forgot what did you mean by this line " and temp jump them to let the Ign coil do Its job.
"

temp jump them to let the Ign coil do Its job.

Didn't mean to get you jazzed. It was simply to temporarily jump the (safety) switches if it was actually on the mower.
