This could be due to a number of reasons, such as a fuel filter that is clogged, a faulty fuel pump, or a blocked fuel line. Other issues include a faulty carburetor, a misaligned float, or a worn gasket.
This would cause the engine to stumble. To address this most carburetors employ what`s called an accelerator pump, which is essentially a gasoline squirt gun that shoots fuel into the throat of the carburetor to enrich the air-fuel mixture in the brief moment before engine vacuum returns.
A working pump will squirt fuel into the carburetor. However, if no fuel appears, then verify the tank has gas and check both the fuel line and fuel filter for blockages. Inspect the fuel pump visually. If fuel is dripping, the diaphragm is faulty and you need a new pump.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
Inside the float chamber of the carburetor, you`ll find a mixture needle. It controls the amount of fuel sent into the discharge nozzle. The mixture control in your cockpit directly links to this needle. The mixture needle is your way to change the fuel/air ratio entering the engine.
If the tank is below the level of carburetor, a lift pump is provided in between the tank and the carburetor for forcing fuel from tank to the carburetor of the engine. The fuel comes from fuel tank to sediment bowl and then to the lift pump.
The carburettor is situated on the cylinder head, between the air filter on one side and the intake manifold on the other. Air is sucked in by the vacuum created by the piston in the intake stroke, when the intake valves are open.
If the voltage delivered to the pump becomes low, the pump will not deliver the fuel at the requisite pressure. A voltage drop is often due to a bad battery or improperly-installed wires. If the fuel lines are cracked or clogged, the fuel pressure will drop before it reaches the engine.
Accelerator-pump system
Open the throttle quickly. You should see the accelerator pump system discharge a squirt of fuel into each primary barrel. The flow should continue for a few seconds after the throttle valve reaches the wide-open throttle position. If not, the accelerator pump system is defective.
Clogged Fuel Injectors
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
Causes of a jammed/stuck fuel door:
Damaged release cable – In most vehicles, a cable runs from your fuel door lever to the fuel cap door. If this cable snaps or becomes loose, there will be no connection and the fuel door will not open. It will need to be replaced in order to open your fuel door.

I have changed the fuel filter on a John Deere L130 garden tractor and the engine is still not getting gas. Is there a fuel pump or other part which would stop the flow of gas to carbuerator?
ANSWER : Underneath carb bowl should be a wire. Unplug it and remove ( unscrew) electric gas shutoff. Replace.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.

I have a Echo leaf blower and I can get it running but then it’s cuts off after just a few seconds. It has new plug, air filter and fuel filter. What else could it be?
ANSWER : The carburetor could be dirty and need a good cleaning and you could first remove the fuel pump cover (cover without the vent hole) to the carburetor and look for the small, round, fine-mesh screen. Sometimes it gets covered with dirt and debris and has to be cleaned as it allows the fuel to flow into the metering side of the carburetor.

Why will my1994 bravada not start?
ANSWER : Very possible your new pump went out again, or was not installed correctly. Check fuel pressure. If you know electrical you can jumper the relay to run the pump. On some GM models I have seen a test wire for the pump underhood.

How to prime a sand filter pump – INTEX Sand Filter Pump
ANSWER : It depends on the pump but most pumps have a filter bowl with a screw on cover – you need to fill this with water and start the pump. if the pipework connected to the pump and the filter are empty you will usually have to repeat this process a few times, but once the pump is primed it should start up without repriming in future – Hope this helps – Nigel
