Customer reply replied 4 months ago
no i would just like to know what it could be
Technician: Hank F., Technician replied 4 months ago

It is hard to say without knowing which variation you have. Different variations have different parts, and different control systems.

But it could be a bad board, broken wire, blown fuse on the models that have a fuel pump fuse.

I have 4 of these generators I switched out board that is good still nothing ,I checked fuses OK checked wires seam OK
Technician: Hank F., Technician replied 4 months ago

The boards are not interchangeable between all specs of this unit.

It is impossible for me to help if I don't know exactly which unit you have.

Since you don't want to get the model number so I can help, I will opt out.

Good luck with it.
