I have a John Deere L110 that won't start. It's not the battery or the starter. The engine turns over but it won't fire and I have already replaced the spark plugs and it did not help.
It seems to be electrical I'm not sure.

o.k. is there fire going to the plugs through the spark plug wires?
Did you remove the black "kill" wire from the coil, (small black wire) and see if it fired?
What type engine is this?
