I completely agree. You could remove the pump and find a truck shop and find out where they get there pumps serviced. They could test it to verify for you.

Ok cool deal what does the crank positioning sensor do and will it keep the engine from starting

Crank sensor sends a tach signal to the ecm. I have never had it not allow a diesel to start from this generation. Have seen solenoids fail. Glow plug controller and plugs themselves, mechanical pumps fail but not sensor failure.

Good luck, by the way, did you try spraying any starting fluid into the air filter to see if it tries to start? Just a small spritz as it can damage the motor if you use too much
