The ignition system, injectors, alternator, and indirectly, the fuel pump all get their current from the automatic shutdown (ASD) relay. The Engine Computer turns that relay on when it sees pulses from the crankshaft position sensor and the camshaft position sensor. Given the recent history of the engine replacement, did you use a thick paper spacer when reinstalling the crankshaft position sensor? If not, it can be slid in too far where it will hit the flex plate and be broken, or it can be installed not far enough where it generates a signal that is too weak.
You can prove the ASD relay isn't turning on by measuring the voltage on the dark green / orange wire, (I think) at the ignition coil, any injector, or either small wire on the back of the alternator. You should see battery voltage there for only one second after turning on the ignition switch. What is important is that voltage must come back during cranking. If it does not, check the cam and crank sensors.
