The failure of a straight-in lighter to ignite may be caused by a variety of reasons. Here are some possible causes and their solutions:
Low gas/fuel:
Check that the direct-injection lighter is filled with gas or fuel. If the fuel is insufficient, it needs to be replenished in time.
Note that direct injection lighters usually use flammable gases such as butane, so make sure you buy genuine and reliable fuel.
Insufficient gas/fuel purity:
Using gas or fuel that is not pure enough may cause the lighter to not function properly. It is recommended to use high-purity fuel purchased from formal channels.
Air pressure problem:
If you are using a cylinder-type direct injection lighter, check the pressure instructions on the outside of the cylinder to make sure the air pressure is sufficient to support ignition.
