This happens when a burner is partially clogged, causing the level of the gas flowing into the burners to be reduced. If you haven't cleaned your stovetop in a while, grease and other cooking residue can build up and clog the burner and reduce the flow of gas.
If your stove is not level, or tilted the wrong way, the gas will not flow past the igniter. Then you'll need a match or cigarette lighter to get it going. Re-levelling your stove will fix this problem. Some stoves come with metal tubes that lead from the burner to the igniter. The tubes sometimes get filled with gunk.
Typically if the burner is not showing a gas flame at each hole then either the holes are blocked and need to be cleaned or the gas pressure is low.
Debris and Contaminants
Debris including dirt and leaves, insects, or even water can causes clogged gas lines. These issues can block the flow of natural gas, leading to decreased performance in the appliances that use it and potentially even creating toxic gas leaks.
There are many possible reasons why the burner will not stay lit - the gas jet may be blocked, the valve may be set too low, the air flow may be restricted, there may be an issue with the pilot light, and so on.

If You Smell Gas but Your Stove Is Off, Leave and Call 911
But when you check your stove, you notice that all of the burners are off. In that case, you might have a gas leak. If so, leave immediately, and call 911 or your local gas company.
If you only have a problem at high demand (i.e. each appliance operates fine on it's own but you get problems when all are running simultaneously) you may have a problem due to the pipework being too small, an undersized regulator, or too small / too few tanks or cylinders. Contact your installer.
If a furnace gas valve shows signs of malfunction, the valve coil may be due for an inspection. The coil may be dirty or covered in dust, preventing it from working correctly. Cleaning the coil with a brush can often fix the problem. Furthermore, the coil may be loose, preventing the valve from functioning correctly.
Gas or bloating may occur if your digestive system can't break down and absorb certain foods, such as the sugar in dairy products (lactose) or proteins such as gluten in wheat and other grains. Constipation. Constipation may make it difficult to pass gas.
Soak the sealed burner base in vinegar or warm water and use a stiff brush to remove any debris. Finally, clean any remaining debris out of the burner holes with a toothpick, sewing needle or compressed air. Reinstall the burner, cover and the grill, and try igniting the burner once more.
Gas Range & Cooktop - Common Causes for Slow Ignition, No Ignition or Clicking on Surface Burners. Gas surface burners are often slow to light or will not light at all because the burner or burners are wet or dirty, the electrode is not seated properly or the burner head and cap are not matched up properly.
Gas may not come out of a tank for several reasons: The valve may be turned on all the way. Improper connection. Faulty regulator.
Common causes include gas leaks, faulty ignition systems, clogged burner ports, or issues with the gas supply. To resolve the problem, you'll need to identify the specific cause and take appropriate action, such as repairing the ignition system or cleaning the burner ports.
The most common reason for the fuel gauge to malfunction in a car is due to a bad fuel sending unit. The fuel sending unit measures the amount of gas in the tank and communicates the level to the fuel gauge in your car's dashboard.
Gas Line Blockage
A gas line can become blocked with dirt or other debris, insects, tree roots, or even water. A bad dent or kink in the line can also block the flow of gas through it. If your gas-powered appliances are not working properly or at all, it could be a sign of a natural gas blockage.
Gas Supply Problems
A defective gas valve can also lead to gas supply problems. If there is no gas flow when you start your furnace, the igniter will make a clicking noise until you shut off your heat.
If your gas burner isn't igniting, it could be because the gas line valve is in the closed position. This valve controls the gas flow to your stove; if it's closed, no gas will reach the burners. To double-check the gas line valve, try the following directions: Locate the gas valve, usually found behind the stove.
Most of the time, however, your external sphincter is to blame. When it's not relaxed—a problem that often occurs when you're stressed out, for example—it clenches up and prevents air from escaping your body, says Dr. Ganjhu.
The number 1 failure preventing a gas oven from heating is a weak igniter. The igniter won't get hot enough to allow adequate current to flow to the safety valve so the valve won't open to let gas flow to the burner for ignition. That's why we recommend testing the oven igniter first.
Always turn off the gas supply at the cylinder valve when not in use, even for short periods. Avoid using electrical appliances or open flames near the cylinder when changing connections or checking for leaks.
