What do I do when on the block where the crankshaft position sensor is supposed to be breaks off and the crankshaft position sensor can't screw into the block the block part broke what do I

What is your question?

Shaft position sensor is supposed to be placed on the block the block broke so pretty much though position sensor can't screw into it no more cuz there's no place where to go how do I fix that?

What makes this problem better or worse?

It won't start cuz of the position sensor not being mountain to the block

How long has your 1999 Chevrolet C1500 Suburban had this problem?

A few months actually
