Running fine, then parked overnight in 20 degrees, cranks but willnot start.
I have verified good battery, good spark, fuel pump can be heard initiating,
reset alarm ignition lock out (cycled locks 5 times), checked fuses,
and still working on it.
Plan to check cam sensor leads, anti tilt switch, etc., etc.,
any and all suggestions are welcome.

 

Do you still have a problem starting? Check fuel pressure at the fuel log... there is a valve stem looking/function on the fuel log... if so then check spark.
