More than likely the problem is in the positive voltage circuit from the engine going into the wiring harness forward to the control. If you find the starter solenoid there should be a red wire off it, same side as where the battery is connected, that goes to a fuse. Replace the fuse and that should take care of your problem. You simply are not getting power to the control.
For any detailed questions on this if needed I'll need the year of the engine.
Thanks
