Diesel fuel pump are mechanically operated only when engine is being cranked so you would not hear any operational noise.
At the fuel pump, check for fuel supply by removing the return hose and cranking. If fuel is being returned, fuel delivery is ok. Test the fuel cut solenoid for operations. Quite often this solenoid fails and it would prevent starting. I have seen cases of the solenoid working but internally the orifice for fuel flow is clogged. You might need to remove the sloenoid to check for clogging.
