The P1320 is ignition related.
If the car was operating correctly with no codes prior to this current problem -- using the P1320 as the starting point is valid. Are you sure this is a new code and not from a previous problem. Did you look up the code on the service book on the forum? Understand the causes?
Throwing parts at a car is not a practical way to trouble shoot. Unless ... maybe .......it comes down to one inexpensive part that typically fails on a specific model Example: ACC blower pac for the Q's and Pathfinders with auto climate control.
The fact that the car died points to a single failure --- not typically going to have all 6 coils fail at once ... or spark plugs. My guess is if you hear the pump -- you have fuel ... and the code coming up points to ignition. Hearing the pump does not guarantee it's working -- but it's a reasonable assumption given that the common failure is silence.
You say you replaced both "crank sensors" -- car has one? The V6 has two cam sensors .. and one crank sensor? I do not believe the cam sensors will give you the code ... the crank sensor will stop the car if it fails. In fact, the crank sensor is a common failure point, will normally fail when hot and is one of those easy cheap parts that I would replace if in your position.
I remember reading about some coil failures back about 10 years ago .. maybe Nissan had a bad batch. That's the only reason to replace all of them (when there is a known manufacturing issue) .. I have had three 2002 Pathfinders and other cars with the Nissan V6 and have never replaced any coils -- or MAF's. People clean and change MAF's when they should leave them alone unless they know it is bad. I have replaced a few crank and cam sensors.
If you have not replaced the single crank sensor -- that's a reasonable part to replace at this point. The failure of that part will do exactly what happened to your car ,, and it's not unreasonable for it to fail.
Many many threads on this forum from people having various engine issues and they often throw parts at the car. With an old car it's sometimes best to have the car's engine properly diagnosed at a good independent -- the $100 is well spent to figure out what is really going on. Often the problem is not from a single cause.
