Generator cranks normally but never starts, eventually times out

Safety first: Turn controller to OFF, open the generator AC breaker, and shut off gas supply if you will be opening fuel components.

• Confirm fuel supply: Verify gas valves are open and LP tank has fuel. For natural gas, ensure other gas appliances are working.
• Check air filter: Remove and inspect the air filter. Replace if dirty or oil-soaked.
• Inspect spark plugs: Remove plugs and check for wetness (flooding) or fouling. Dry or replace plugs as needed.
• Smell for gas at exhaust: After cranking, a faint gas smell at the exhaust indicates fuel is reaching the engine; no smell suggests a fuel delivery issue.
• Limit crank attempts: Avoid repeated long cranks to prevent starter and battery damage. After several failed attempts, contact a technician.

Persistent no-start conditions usually require professional fuel pressure and ignition diagnostics.
