Rebuilt engine myself. I replaced some of my ignition coil and had to use some used coils. I have some that are 5.4 and some 4.6. Truck ran bout a week no issues then I parked it and now nothing. Crank no start getting fuel and loud backfire but all eight cylinders are firing.

Check if some or most of the spark plugs are gas fouled and smelling like gasoline.
If they are, make sure the fuel pressure isn't too high, maybe from a kink in a fuel line causing backpressure and the fuel pressure to rise.
The fuel pressure should be 35-45 psi, key on/engine off.
