Generac standby generator won’t start
The Generac standby generators may have a problem when it comes to starting. Just like other Generac generators, the reasons for not starting might be similar, and this requires you to check for any.
The spark plug may have a problem where it can be damaged, or it shows the signs of wear. Ensure to examine if the plug is defective by the use of a tool like a spark plug tester.
Additionally, there may be another major reason as to why the Generac standby generator won’t start. There are chances that the carburetor of the generator may be clogged. Issues of fuel being left in the generator for a long time can make the carburetor clog.
Generac propane generator won’t start
There are those Generac generators that operate using propane, and they may have a problem with starting just like any other Generac generators.
Fuel can be one of the reasons that the generator won’t start running and you have to check if it is available. After checking on fuel, you have to find out if the air intake or filter and the exhaust pipe are in good condition. You have to start by checking the spark plug and see if it is in good condition.
If the spark plug has no problem, it is time for you to check on other parts of the generator that are more expensive. It is time for you to see if the regulator is running normally and if not, you need to have it fixed so that the generator starts to run.
Generac natural gas generator won’t start
When your natural gas Generac generator has a problem with starting, there may be some reasons behind it. The most common problem can be fuel, and just as its name suggests, they run on natural gas.
Check whether your natural gas supplier is keeping things going and if the gas is supplied, it is time for you to look at other issues that may likely cause a problem.
Down at the right, you will find you will see some two wires coming from it. Pull out the one that is on top to ensure that the gas comes out. If that does not work, it is time to see if there is a spark coming from the spark plugs. If it checks out, then there may be something that is shorting out the ignition coils.
Generac generator won’t turn over
We have looked at some of the reasons as to why your Generac generator won’t start. Fuel supply is the first thing to look, ensure that it is available so that you get to know the other reasons as to why your Generac won’t turn over.
At this time, you have to check your ignition coil since it is responsible for sending power to the spark plug when the generator’s engine is running.

You need to find a specialist who deals with Generac generators, and he will help you troubleshooting your generator. We have outlined some things that one can do.
Ensure that fuel is available
There is a chance that the generator was used before and it has not been refueled. Also, the system of the generator may also have sprung a leak hence the fuel may not be available.
The mechanical gauge to show the level of fuel in your generator can stick, and this will give a false level of fuel. Some fuel tanks may fail to start your generator in case the fuel level is low and therefore, you should check the level of fuel periodically and top it as required.
Check all electrical connections
Ensure that all wires that are visible and the fuel lines are tight and snug with no cracking or fraying. In case of a wiring issue, it is better for you to call a professional to fix it. Additionally, ensure that the generator is engaged and the switch is on the ‘on’ position firmly.
If the generator has served for some time, it can develop a sticking issue, and the switch may not fully engage without you pushing it. It may not sound helpful, but you will realize that the generator will have a problem in operating. Remember that you cannot handle all issues and therefore, a professional should be there to help.
Champion generator won’t start
The champion generator should be reliable like any other generator since buyers require them for purposes of emergency.
For people living in remote areas, it will cause some minor discomforts when the generators fail to start. It is crucial to note that unexpected failures can happen even on brands that are popular like champion especially when the generator has not been in use for a while.
Low fuel level or degraded fuel can cause the generator not to start, and therefore you should check to refill or change the fuel.
How to fix a champion generator that fails to start
Check the starting system
Some of the champion generators are not simple to start, and this will cause problems with the air filter. In case the air filter is dirty or blocked, the fuel won’t properly burn since there is not enough air supply.
You have to use your manual to find the air filter to fix it, and it is usually found in around the choke from the front side. Be keen when opening your generator and while cleaning it.
You can remove the air filter and replace with a different one. Sometimes, you can clean it depending on the model of the champion generator.
Examine the batteries or the spark plug
If you realize that the air filter has no problems, it is time to inspect the spark plug. Test it to find out if it is still working or it is already damaged. You are free to clean it, but if it does not work, you better replace it with a new one. Ensure that the wires are properly installed when installing a different spark plug. Some models have an electronic system of starting hence you should pet some new batteries to start the generator properly.
Check the level of oil
Most of the champion generators are built with a low oil sensor which will prevent them from starting in case the level of oil is too low. It is your responsibility to check indicator and see the oil’s actual level in the crankcase.
If the oil is required, you can only add the one that is preferred by the champion’s manufacturers. In case the oil is enough and but the sensor shows otherwise, then it may be having a problem.
The manual can help you locate it, or you can trace the yellow wire in the crankcase.
Check the fuel level
The generators can degrade the fuel or the full has been in the tank for a long period of three months. This will not be good for you since it can clog the carburetor and therefore you need to fix properly drain it.
A clogged carburetor can be one of the reasons behind the failure to start off your champion generator. You can remove the carburetor, clean it properly. In case it fails, it is advisable for you to go for a new carburetor. You can now try to restart your generator.
Common reasons for Generac generator failure
The generator battery:
A large number of Generac generators fail due to damaged batteries. Once the generator’s batteries fail, they won’t hold a charge for long hence they will not start your generator.
Failure happens when the battery is recharged and discharged too many times.
It is advisable for you to replace your batteries if it has been neglected or has been in use for about three years.
In case the coolant level is low due to leaking, or the coolant is not properly flowing; it makes the engine of the generator to get hot.
The sensors on the generator will detect the heat, and it will shut down. Occasionally, dust, grit and internal corrosion hinder the radiator core hence you should check for the cleanliness of your radiator.
Always remember to check for any coolant leaks internally in case the oil is discolored. Ensure that you follow every detail that we have outlined above so that your generator serves you well for a long time. Some Generac models can be very expensive, and you will have wasted a lot of money if they fail to work.
13 common reasons why a generator won’t start
