Spark plugs are screwed into the cylinder head and have spark plug wires leading to them from coil packs or the distributor.
DISTRIBUTORLESS IGNITION SYSTEM
General Information
Maximas with the VE30DE and VQ30DE engines use a distributorless ignition system that is controlled by the Engine Control Module (ECM). The ECM receives a signal from the crankshaft sensor, and processes the signal based on inputs from other various engine sensors. Then the ECM sends signals to each of the individual coils in the proper firing order.
This system is more efficient than a distributor, and has less moving parts. The high voltage coils are directly attached to each spark plug, allowing a higher energy spark within the cylinder. A high energy spark means a faster, more thorough burning of the air/fuel mixture, which produces more power and less emissions.

Spark plugs are located below the coil on the 1996 Maxima. There are no plug wires on this model.

Using an Allen/Hex key tool, remove the cover to gain access to spark plug holes. This engine has coils at each plug, so after unplugging the electrical connection, you can use either a Phillips screwdriver or an 8mm socket on an extension to remove the 2 screws securing each coil. Pull out the coil and then use a 5/8" spark plug socket on a 6" extension to remove each spark plug. Gap the new plugs to .040" and apply anti-seize lubricant to the threads. Install each plug, slowly at first, so as not to cross-thread it. Torque the plugs to 18 lb/ft. Apply some dielectric grease to the inside of the spark plug boots and re-install the coils. Plug them all back in and re-install the covers. You're done!

This
sounds funny but disconnecr the battery and then hook it back up-I did this and power was restored to my radio-I have no idea why this worked.
Good luck!!!!!!!!!

This car has seporate coil packs for each cylinder, have you tried swapping the front bad one with a good one to see if they switch ?
The engine you just put in may have come with some blown coils.
Hope this helps
