Propane Generator Cranking But Wont Turn Over

[RV Fly Fisher]

Howdy All-
We recently had a major home addition completed.  General contractor wired the 30amp RV plug at 220.  Our new Lance Truck camper rode the lightning and we fried a bunch of stuff.  I have repaired or replaced everything that failed at this point except for one item.  Our Onan 2400 Propane generator is for some reason not turning over.  It is cranking well enough but just wont fire up.  I am curious if anyone believes this could be related to the 30amp @ 220v issue or if this is simply a coincidence and i have some other issue like regulator etc..  I have checked our main panels fuses (all good), i checked the shore power to generator switch (all good), and i checked the circuit on the generator as well (all good).  any other areas i should be looking?
apprecaite any and all inputs on this one!

thanks
Kevin in Nor Cal

Remove a spark plug, lay it on the block and hit the starter to see if in fact you are not getting spark. Better yet use an inexpensive inline spark tester from an automotive jobber. That unforgivable wiring booboo should not affect the generator ignition.
