WON'T RUN AND BACKFIRES OUT INTAKE

2000 Nissan Maxima

Electrical problem
2000 Nissan Maxima 6 cyl Front Wheel Drive Automatic 77000 miles

Irecently replaced the engine in a 2000 Maxima, and swapped all injectors and coils from old motor to new. Tried all new sensors, new starter. What could be causing it to backfire out the intake and not run? Been looking for answers, but no luck yet. Any ideas?

Hi: Is the engine a direct replacement? Has the timing been checked? Has compression been checked?
