Is it not cranking? Or cranking and not firing?

it cranks but won’t start and backfires

Might be flooded. Push the accelerator flat to the floor, leave it there, and then try cranking the engine.

have you checked the oil level is accurate
have you double checked what oil you put in it
did you have the engine cover off at all

I put 20w50 gulf western oil
And the oil on the dip stick is 1mm under full
