Does anyone have any ideas of what to look for?

Power is supplied to the coil packs and injectors from the power delivery module (fuse/relay center). Coils and injectors are actually triggered by ground signals from the PCM (Powertrain Control Module).
First verify grounds. In swapping out an engine, many wires are disconnected. You may have left loose a ground feed to the PCM.
Next, verify power to the PCM. Could have easily popped a fuse. Will be separate fuse from fuses that power the coils & injectors.
If you can access a good scan tool, see if you have any codes. Make a note of them. Clear codes and see if any come right back. Those will be hard, current codes. They may lead to the trouble. Codes that don't return may well have been set accidentally while working on it.
