engine misfire?

when my 97 jeep has 1/4 tank of gas left, when i take a left turn(yes only on left turns) it stalls out, turns off completely, power steering and all(at 1/4 of gas in the tank i can sometime avoid stalling out by taking turns very very slow...i would then have to throw it in neutral and start the engine again, quite embareassing when you have people driving behind you and screaming at you when you all the sudden stop in the middle of the road.
as the tank nears empty i can no longer take left turn slow, it will do it every time..and again when my tank is really low i can floor the gas when taking a right turn and nothing happens but if i let my car even just cruise into a left turn (from being in a dead stop), surely enough...car is dead?
can anybody explain what may have caused this?
what it is, engine misfire?
and how i can fix it?

sounds fuel pump related. if memory serves, the fuel pump is in the left side of the tank. Left turn, the gas sloshes to the right, starving the pump.
If you aren't experiencing the same problem with more gas in the tank, it may not be the pump. it may be a baffle around the intake that has come loose. Although, I have a '96 and my pump kicked the bucket around 130,000 miles. If it is the pump, it's not pretty, cost me about $900 to have it fixed.
either way it involves dropping the tank, which is the source of most of the expense.
One last thought. try not to run the tank down below 1/4 full, the gas keeps the very expensive fuel pump cool. I learned this after replacing my pump.

that sounds like a problem that would occur even if the fuel pump is in top working order because, according to what you are saying it taking left turns that is the issue...sloching the gas to the right of the tank where it cant be taken in by the pump (whether it be faulty or new).
im not saying you are wrong, just trying to get it all straight. also, why did you have to pay $900? i looked online for a new fuel pump and i saw them in a range between $50-$200, dropping the tank and whatnot cost that much to all add up to $900!?

I didn't do it myself, I had my mechanic do it. So I paid full retail. nowhutamean?
You indicated it was stalling when taking left turns.
So, when the tank is full does it stall in left turns?

no it doesnt stall when the tank is full, but id say no because when it is full there really isnt any room for a full tank of gas to slosh over to the right when taking a left turn, therefore not starving the gas pump.

not sure if your's is the same , but I have a 1993, and the pump is servicable with tank in place! I got the pump and Auto Zone w/ new gaskets and pre filter for 80.00 w/ a 1 yr warrenty! Know I just need to get out and replace it.... :banghead:

consider yourself fortunate Zepp. From '96 on, the tank has to be dropped to remove the fuel pump.
Ok, so with a full tank no stall, it's not the pump.
There is a baffle around the pump to retain fuel when the fuel level is low, so that the pump does not get starved for fuel when changes in direction occur, starting, stopping or turning. I suspect the baffle is the culprit. it is not longer containing a supply of fuel around the pump, so when you turn left, the fuel sloshes right, and the pump is starved.
One sure way to find out, depressurize the fuel system, drain the tank, drop the tank, pull the fuel pump and take a look. If the baffle is in place and firmly affixed, then my suspicion is incorrect, and it's the pump.
