Top 5 Reasons Your Generator Won’t Start (And How to Start It)

Are you a generator owner, and your generator is having a problem starting? 

You don’t have to panic. This article will in various ways explain the reasons why your generator is failing to start and the easy ways through which you can bypass these problems and make it start.

Let’s get started.

When your generator fails to start, there are several reasons for it, which will be discussed in detail:

1. Verve

Generators failing to start is commonly one of the top reasons given by generator users, and verve is one of the major sources of this problem. However, smaller or portable generators, for instance, the Tiger 960 VA generator, don’t make use of this type of verve, they have a different verve entirely. 

Verves are used to pressure the generator. If slack, there’s no way your generator can start. 

How can you solve this problem?

Whenever your generator develops this fault, the best way is to take it to a generator engineer to check if it’s the cause. And if it is, he will remove it and do the needful.

How can you know verve is the reason why your generator is not starting? 

If you want to know if it’s your generator verve that’s causing your generator to fail to start, try starting it manually or automatically. If free and has no pressure for starting, the verve is the reason why your generator is failing to start. 

2. Spark Plug 

Another reason why your generator fails to start is that the spark plug is having a problem and needs intervention. However, not at all times, spark plugs can be the reason why your generator is failing to start. In short, it might be the least

How to know if a spark plug can be a reason why your generator fails to start. 

After trying to turn on your generator for several minutes and getting suspicious of the plug, there are different ways you can know if your spark plug is truly the cause of why your generator is failing to start.

How to solve this problem: 

Firstly, remove the plug and clean it; you can clean it with anything available. If the problem continues, remove the spark plug again, but this time you are doing a different thing. 

There’s always a wire connected to the plug and also a cap. Fix it to the plug and pull the starter or the ignition switch. If the plug pulls out a light means the plug is not the reason why your generator is failing to start.

But in the case where there’s no light sparking out from the plug, that’s not the end of it, because it might be caused by another problem. And this time around, you will have to remove the cap that has been fixed on the plug and use the wire directly pointing it towards the engine’s crankcase. If it sparks, it means you have to change the plug, but if it doesn’t, it means you will have to change the ignition coil.

3. Low Oil In The Engine’s Crankcase 

Another reason why your generator fails to start is that there’s a low oil level in the engine’s crankcase. However, at most times, there might be no low oil level, yet it will still prove that there is. Moreover, if there is a low oil level, you can add more oil to make it reach its recommended level. 

But in cases where there is no low oil level, there are other options available, which are by disconnecting the oil wire or changing the oil switch, which can be done only by an engineer. 

To disconnect the oil switch wire, it can be found by the side of the engine’s crankcase, and it’s mostly yellow. But it’s dangerous if you are the type that doesn’t care about your generator’s oil usage. This is because after the wire has been disconnected, there will be no alarm if there’s a low oil level or not, and this can cause major damage to your generator.

4. Choke On The Carburetor

You might be asking how a carburetor choke can be a reason why a generator is failing to start. 

Yes, it’s one of the major reasons why the generator will fail to start, especially when it’s in the wrong position.

How can you tell if a carburetor choke is causing your generator to fail to start? 

In every generator, there’s a carburetor choke, and if this carburetor choke is not fixed at the right position before trying to start your generator, there’s no way your generator can start.

At a normal level, all carburetors should be positioned “closed”, not half-closed but full. And after starting the generator, it can be positioned “opened”. 

Which means that if your carburetor choke is fixed open or half-closed when it’s supposed to be closed, there’s no way your generator can start no matter how hard you try. 

Best ways to solve this problem. 

If you want to fix this problem, you need to place the carburetor choke too close to the ignition switch and try starting your generator. 

But in some cases, your generator choke sometimes doesn’t need to be fixed when trying to start it. For instance, when the generator has worked for some hours or minutes and you put it off, then instantly want to put it back on—the carburetor choke should be kept open.

5. Gasoline Scarcity 

Another reason why your generator is failing to start is that there’s a small amount of gasoline remaining in your generator’s tank. The shortage of gasoline can result in not enough gasoline entering the carburetor, clogging it up and making it insufficient for it to put the generator to work.

How to solve this problem?

If you want to solve this problem, you will have to add more gasoline to your generator’s tank and let the gas flow naturally through the clog before trying to pull it on. And again, don’t forget about the carburetor choke as explained above. 

But in cases where gasoline has spent a long enough time in your generator, it will be best to change it and also service your carburetor. 

However, in some cases, there will be no gas shortage but yet the gas is not flowing naturally into the carburetor. This means there’s a blockage in the fuel valve and it needs to be checked.

6. Carburetor

A carburetor can be another reason why your generator is failing to start, especially when there’s no fuel in its tank, the fuel valve is put closed and not on if it requires service or has been kept down for a long time without use.

If your generator has been kept for a long time without you using it, it will be best if you service it before trying to put it on. 

Nonetheless, these are the various reasons why your generator is failing to start. Though, these reasons apply to all generators, especially gasoline generators.
