What is the model number of the genset?
If you are not getting power to the fuel pump while cranking the engine, the controller is bad.
If you are getting power while cranking, but not after you let off the start switch, either your alternator is bad, or the fuel pump relay is bad.
If you remove the front panel like you are changing the air filter, the relays are to the left of the air filter.
It is much easier to get to the relays by removing the top cover of the genset, if you have enough access to remove the top cover.
