1995 nissan maxima stalling issue

Try checking the harness to your fuel pump, run a ground wire somewhere onto gastank from body of vehicle but must be rust and paint free or a ground wont contact (dont weld or put screws into tanks maybe the edge or corner can be cleaned and a tiny hole - use a brass wire brush that wont spark eh, or if there is a leak in lines you are sucking air lol but that would be more sputtering and hard starting. that thing is old and inside tank rusty perhaps and sucking this rust into filter and another filter on fuel pump & pick-up tube if pump is inside the tank, some vehicles have a port under the back seat to access fuel pump & sending Unit. The fuel pump relay could be pitted so switch that with one of the others with same numbers,
there is a big steel ring around fuel pump *& sending unit access port to seal it and this area has to be cleaned so you tap the ring into unlock position tapping with hammer and brass punch so as not to spark, be extremely careful as rusty lines could break - once the ring is turned the sending unit will come out of tank being careful to not damage the float that is attached which runs to a rheostat to give you your fuel level.
once the fuel pump is out you can carefully disassemble and replace with a new or used pump from reputable used auto sales, but never pay 400 for complete sending unit that's for the rich & lazy.
when the fuel pump comes out put a rag in the hole as any spark is a boom! So, check filter at end of the pump and pick up tube and shake and tap and rust debris out of fuel pump can connect to a cheap 9 volt adapter (never the car battery (too many amps) but a 9-Volt rectangular battery is ok like the kind in a smoke detector!! or 9 volt DC power adapter with 300 milliwatts just for a few seconds to see if pump pumps, or perhaps in reverse for just a second or 2 to pump out old dirt but needs to be submerged in fuel to do so which is totally dangerous so ya not for everybody and be good to know the polarity and just brush the wires together for the first tests and I dont actually suggest all or any of this for anyone to actually do this as I have in the past but if you are brokea$$ and gotta, then just dont blame me for your stupidity of you make a mistake or deem this rediculous but this is backyard style.
just a few tips...
sounds very difficult but likely something simple.
\I would invest in the cheap bluetooth OBDII auto diagnostic tool on Ebay for 10. or so. Every car should have one and or everyone! Dont pay dealer 90$,
Good luck.
