First, you have been around here long enough to know that "won't start" is meaningless. Did it engage the starter or not?
A failed RCM (if it won't engage the starter) or Crank sensor (if it engages the starter but won't start) are common "no start" causes.
If the code reader can't talk to the ECU, then I'd suspect that the RCM not powering up the ECU.
But none of this explains a 'loud bang and smoke'.
