It will turn but when you say spark im guessing you mean fire up or turn over. P. Like it gotta sit and cool for a minute for it to turn over. So im guessin nono when it comes to spark new spatk and wires. Fuel, water pump.

No when I say do you have spark I mean when it won't start you check for spark and look for a flashing spark while cranking the engine?
