new crankshaft sensor broken off

I believe the guy I thought could fix the truck could put in a crankshaft sensor brand new turned it over a few times. No spark after discovering the new crankshaft sensor broken off wondering if it still can be good or no and what could have caused this to do what it did possibly not installed correctly? I know just wanting to have other feedback to help me decide get this one is usable or not. The truck listed above has the 8-cylinder plugs.
