Gas tank problems. when my gas meter gets to 1/4 tank, the truck cuts off.

This almost seems like the vent on the gas tank is not allowing air in the tank as the fuel level drops. When the suction in the tank gets too high, no fuel flows.

Replace the fuel pump assembly. The in tank fuel pumps also have the fuel gauge built into the same assembly.

Please verify this through a parts store but that is my initial thought on this problem.

GOOD LUCK

get the OBD codes read as you wont always get the CEL , i'd start there

CHECK GROUND WIRE @ TANK/PUMP/SENDER ! #1 PROBLEM W/ SENDER/GAUGE ISSUE ! SENDER IS A OHM METER, IT CAN BE MEASURED . 0=EMPTY TANK,, 45=1/2 TANK,, 90 OHMS =FULL TANK, UNDERSTAND ?

The sending unit is going to be inside the gas tank so..........

By gas light I am assuming you are talking about your gas gauge that tells you how much gas you have. This is probably your fuel pump level sensor. The fuel pump has a float mounted on the sending unit which floats to the top of your tank when it's full and gradually decends into the tank as you use up your gas. Most commonly, the float builds up residue that in your tank which causes it to stick in one place which can explain why it's cutting off at a 1/4 tank. I hope this helps you solve the problem.

Put a volt meter on the battery itself and take a reading when it is doing that. If charge rate is over 14v the alternator may be working but the output is not being cut down to "useful voltage" You may have a regulator problem.

wet gas. dry gas is like 3 bucks a can and helps get rid of water in the tank....try it can't hurt.

no fluid on ground right?then it must be your float on your fuel pump.drain gas from tank and take both ''straps'' off.remove both fuel lines.be carefull some gas is still in lines.on the top of tank there will be a wire connector.unplug it,remove tank from under car.remove bolts on the fuel pump.you might be able to buy float sepertly.if not you might have to buy the it as one unit.

I wanted to just give a suggestion...do you go to the same gas station to get gas? My sentra ran horrible because I kept going to this same gas station. My gas would get low and it would start cutting off and trying to cut off. I let my fuel go to almost empty and then went to another gas station to fill up. It hasnt cut of for about 6 months now and I havent returned to that gas station.
