Possible theft detterent system problem (VTD Fuel Disable).

Try shooting some (go easy) starting fluid while cranking and see if it will light off.

Probably an ignition (spark) issue then.
The ignition wires may be in the wrong order or the timing is too far out of range.

On a scale of 1-10 (10 being a proffesional) how would you rate your mechanical skills?

In reference to your PM: Your truck does have an vehicle anti-theft device called Passlock II but this ystem does not include the old style diode embedded in the key.
