THE PLUG WITH THE TWO WIRES THAT GOES INTO TO THE COIL PACK IS NOT GIVING POWER TO THE COIL PACK.

Need to give us a bit more info. Which engine? Assuming no spark? Without that, crank sensor would be just a guess.

the auto shut down(ASD)relay provides power on this truck on a dark green/orange wire to the coil/injectors/alternator field/and 02 sensor heater.See if power on these components.Just go to the ASD and check output voltage.fuse 20 i think provides power on a red/yellow wire to the power side of the relay.20 amp fuse check for power with key on.some pcms store codes relating to the asd relay.you should also have power to relay on the orange wire that comes from the ignition switch on the control side of the relay.Both the orange and the red/yellow wire should have B+ on them.red/yellow wire hot at all times and the orange wire hot with key on.Check voltage on the dark green/orange wire key on and cranking...............we can go from there.
