My 95 yj hard too start after i change my fuel

NO YEAR told at all and wants help, do expect lies like this.!!
are you confused, ???? you never once told your hard proof of low fuel pressure ( a real shop hand gauge,: or the silly OBD2 scans sent you DTC code for tank pressure, oops that is Evap fumes pressure and not fuel line pressure. or is. zero proof by you.
PUMP 101 DAY, (PURE PHYSICS)
if the sock is packed up, the pump can not suck fuel from any tank if the sock is packed up,. but gee its new right.
the pump is fuel cooled and fuel lubricated never never run one day. ever ASE 101 fact 1 , fuel pumps

why not tell the full story so real techs can answer this.
engine will not start or lacks power.
the fuel rail PSI is low? what?
zero evidence provided.
you say pressure is low HOW,and not told once HOW low PSI
hopeless to answer, me,
To fix cars we do tests and do them in a correct and valid way.
no engine size told not even gas or diesel or LPG or CNG or what.

all I know is 2 things a car body
Nissan Sentra and some problems NOT TOLD.

If at all possible, get a second opinion. Preferably someone who specializes in diesel service.

Check the fuel for a presence of water. I'm sure there was a recall notice on the gasket on top of the fuel tank where the sending unit mounts. My YJ sat for a year and had water in the tank from this leaking. Drain and drop the tank, replace the gasket, and reinstall.

try checking the pressure of the pump.

check fuel pump relay, check main fuses

test replace the fuel pump relay, make sure the relay socket has 12 volts to 2 of it's terminal when the key is held in crank position, if not you may have a defective ignition switch or Powertrain control module (PCM)

I know it sounds crazy but check to see if the floor mat is blocking gas pedal. I have seen this alot in my 30 years as a master tech.the way you describe it sounds like all the other cust of mine that had the same issue. hope that is all it is. good luck and let me know.

Have you tried replacing the starter? I know starters can go bad if the car is not started or run for a long time.

I am getting the same car, with the same issue.. it sat for 2 yrs and won't start.

My mechanic told me it is probably a starter.

have you checked the fuel pump ? the fuel pump is in the fuel tank and it may be that the fuel guage inside the tank is broken and or not attached to the pump. This is a big job but with a little help from buddys and a bit patients it can be repaired.
