2002 GMC Sierra V8 Four Wheel Drive Automatic

I have a 2002 GMC Sierra Heavy Duty 6.6 Turbo Diesel.

I changed the crank sensor, but it will crack, but not turn over. The main problem is getting the vehicle started.Do i need to re-program the ECM once i changed this sensor? I hooked up a pressure gauge and there is no/very little pressure coming from the injectors. I've also try placing the suction line in a pale and there was no pressure.

If you could provide some feedback that would be great
Thank you in advance.
