Make sure that all of the original 2002 elements are in place: Key with transponder, immobilizer box, and DME (ECU).
Ground not correct? Big ground wire in the engine compartment. Bundle of brown wires in the trunk by the DME (ECU), brown wire that bolts to the floor by the immobilizer box under the seat.
Is the starter known good?
Is there more to the story? Could the car crank before you started on the engine swap...?
