no codes?

Thats a typical sign of a stator or pickup coil going out but usually there is a code (12) to go with it.

I had a problem a few years ago where the sled would turn over, it would catch, backfire, pop etc but would not start. This eliminates fuel, air, spark as even a backfire requires all of those, so you should just be down to timing. The problem I had was the stator was toast.

Going to try change stator hopefully that will change everything n fire up

Exhaust donuts?

Would that cause it to not start at all?
