As said bad gas or no gas.

I always add 3-5 gallon gas to be sure not out.

Check fuses for blown fuse.
Check for good hot blue spark to all plugs.
Rent or borrow a fuel pressure test gauge and check for good fuel pressure.

To check for a fuel delivery problem.
Squirt some carb cleaner into intake while cranking.
Ir it runs on carb cleaner you have a fuel problem.
