The problem with your truck is not the fuel pump. Its the sending unit for the pump, which is on top of the fuel tank and feeds POWER to the fuel pump. Nissan has a campaign for it, because those units corrode internaly inside of the connector, that sends power to the fuel pump to power it up. Have the dealer run DCS check , to see if you have a open campaign for the sending unit. If you do, it will be free of charge and in some cases the whole fuel tank needs to be replaced also. However, that may not be your problem. I have seen ECM/computer getting flooded by the heater box. There is a drain tube, that drains your heater box, that tube gets clogged up by debriss/stuff and that's when water has no place to go and it leaks on top of you ECM/computer and fries it. Have you noticed any wetness on pass. side floor?? Right by the fire wall. Check it and make sure that its dry/carpet area at the top of the carpet behind the glove box. If its wet, that's not good. Let me know what you have found and will take it from there. Is the "Check engine light on" by chance?? Let me know.

SOURCE: 2002 Nissan Frontier timing belt
Timing belts are found on the 3.3L engines, timing chains are on the 2.4L engines. The 2002 3.3L Timing belt is changed at 105K during the major service. This service can run over one thousand dollars. It is recommended to replace the belt, tensioner and idlers, cam and crank seals, water pump, and both belts when changing the timing belt. That way, you only open up the front of the engine every 105K. Why change the timing belt and have a water pump start leaking only 20K later and ruin the belt with antifreeze? Other items during the 105K are a major tune up with all the fluids changed and a lube. This does get expensive. You can break it up into several blocks of time and spread the related service items out over a few months to take some of the sting off.

SOURCE: poor idle
my truck was doing the same thing, i tried to adjust the idle screw and replace the ignition system but it didnt help. What i did was replace the carb with a webber and the problem was solved. I'm not saying to buy a webber but you might just need to rebuild your carb or something similar

SOURCE: COLD START ROUGH IDLE
I hate to be the barer of bad news, but may be the head gasket.
My car started with rough idle. Then very hard to start in cold weather. Next started overheating, but no output from heater. Trickling sound from behind dash board. Overflow bottle overflowing.......
I replaced the water pump, radiator cap, thermostat, coolant, fan belts, power flushed the system. Nothing worked. Some research gave me the answer.
The head gasket leak was allowing exhaust gases to enter the cooling system, displacing the coolant. After use, as engine cools, coolant is sucked back into the system and coolant seeps into the cylinder. This gets worse over time.
First thing you'll notice is the rough idle as the spark plug burns off the coolant in the cylinder. (This is especially true at low temperatures.) If it is the head gasket, the other symptoms will follow as time goes by.

There is a relay on the rh passenger side kick panel above the automatic transmission module that is controlled by the ECU through the MAF sensor that controls your fuel to the engine so the air / fuel mixture is correct. I fixed a pathfinder one time with a similar stalling problem.
