John Deere L130 cranks but won't start

My John Deere L130 won't start after winter. Battery is good. It cranks but won't start. I added more gas and checked fuel line. Up to the fuel pump, I can siphon gas. However, the unplug the output pipe from fuel pump, no gas out of it. Can I conclude it is fuel pump issue? It seems I can't open the fuel pump. It is a plastic one and no screws to open it. It is possible the engine part has problem? The pipe to the engine should blow air or suck air? How can I test that? Thanks!

Do you have a fuel filter? Before or after the pump? Fuel visible in it? I think the engine should start on what's in the carb fuel bowl as long as gas can get that far. The pump comes into play once the engine is running.
Does the carb have a wire connected to the bottom of the bowl?

I have a fuel filter. It's before the fuel pump. Fuel is visible. I disconnect the pipe going into the pump. I can siphon gas from it. When I disconnect the pipe going out of pump, it's dry. No fuel comes from it when I crank the engine. A third pipe on the pump goes to the engine. I don't know how to test that one. I haven't checked carb yet.

Make sure the line going from the pump to the carb is not cracked and leaking air. This is what drives the pump and if it is leaking air, it won't pump the gas.

Confirmed, it is the fuel pump problem. I bought a new fuel pump and changed it. It worked immediately! I wonder what the winter did to it. Frozen to death?
