my best guess is you put the 4.7l engine in your truck and did not swap over the correct timing gear like the crank and cam tone rings and is giving the computer an incorrect reading of when to create a firing event therefor no attempt at running. just fixed the same thing on a customer vehicle were he put the jtec version of the 4.7l in the ngc version of the durango and would not start/run. if thats the case the engine has to come back out.
