The old sensor and the new sensor looked and weighed the same.

I drove the truck for a week, but starting each time the starter was engaged took a long time.

A Diesel engine machinist told me that if the Cummins was hard to start, it could be an injector was bad, and he had seen engines destroyed by a bad injector.

I don’t think this applies to this situation, but I sidelined the truck until the problem could be investigated.

From my understanding, the injector number has to be read off each injector and written to the new computer.
