Possible Causes
Fuel shutoff valve closed, Clogged fuel filter, Air in fuel system, Faulty ignition components (spark plugs/coil on gasoline units)
How to Fix / Troubleshooting
Safety first: Turn the generator OFF and disconnect battery negative. Keep flames and sparks away from fuel components.
Steps:
- Verify basic conditions: Confirm fuel level, check that the main fuel shutoff valve on the Gillette skid is open, and ensure the engine oil level is correct.
- Fuel filter and lines: Inspect fuel lines for kinks or leaks. Replace the fuel filter and bleed air from the system per engine instructions.
- Ignition (gasoline/LP): Remove and inspect spark plugs; clean or replace if fouled. Check ignition coil connections and plug wires.
- Air intake: Inspect and replace a clogged air filter element.
- Test start: Reconnect battery and attempt a start. If the engine still will not fire and no code appears, deeper diagnostics (compression, injector testing) by a technician are recommended.
