Once it sits for a few minutes it'll crank but just spit and sputter and then die. Can't drive it at all.

Poured since gas in that carburetor looking thing and it would crank. I can hear the fuel pump prime but it's like it's not getting gas

Sounds like a bad fuel pump, but to be sure you get a fuel pressure gauge and check the fuel pressure.

You should have 38 to 42 lbs. fuel pressure, and at an idle it can be as low as 31 lbs.

Nope fixed it. It was the fuel filter. Put gas in that carburetor thingy and took a few times but we got it running. Thank goodness. It's fine now. $12.84 fix plus all the hours we spent trying different things. I'm just a girl but I'm learning good. Thank you for your input, I appreciate you answering me....
