How to troubleshoot Generac Power Systems Lighting Equipment that cranks but won't start?
- Y
  yphillipsJul 31, 2025
  If your Generac Power Systems Lighting Equipment cranks but doesn't start, it could be due to several reasons. First, check the fuel level in the tank. An obstructed fuel flow could also be the culprit, so inspect the fuel pump operation, the fuel supply hose from the tank to the fuel filter for any cracks or abrasions, and check for gelled fuel in the fuel system, especially at the fuel filter during cold weather. Air in the fuel system can also prevent starting, so purge any air from the system. Additionally, inspect the air filter for any blockages. If the glow plug(s) are inoperable, refer to the OEM engine operator’s manual for additional information.

  If your Generac Power Systems Lighting Equipment experiences a high coolant temperature shutdown, take the following steps. Allow the engine to cool, then check the coolant level in the radiator and add coolant if needed. Inspect the radiator surroundings for any blockage and remove any foreign matter. Check for visible coolant leaks and inspect the tension of the water pump drive belt. If the cooling fan is inoperable, remove the load on the generator and restart the engine. Also, check the coolant temperature and shut the engine down immediately if it starts to overheat.

  If your Generac Power Systems Lighting Equipment stalls when export power is used, it may be due to the load exceeding the unit's rating. Turn the outlet breaker ON and the load sense switch OFF, then confirm that the generator output is 60 Hz ± 2 Hz before reapplying the load.
