I replaced a fuel pump in 94 jeep and fuel gauge still dont work what could it be?

check your fuel pump relay. if not that, then it's your fuel pump. the gas gauge is in the fuel pump, so if your fuel pump stopped working, your gas gauge won't work

getting? means?

1. engine dont run?
2. spark is dead and PCM cuts fuel , they all do that by design.
3. pump pressure is 0 psi, with gauge
4. cranking the fuel rail is dry?
5. runs on test fuel so , fueling must be missing sure)
6. lots more. but ill stop here.

I think your fuel pump MAY be failing, Luther. It may also be stopping because it thinks it's pressurized the fuel enough, though. Have someone check the fuel pressure and flow rate at the fuel rail with the appropriate gauge.

If your "Check Engine" light is on, also have someone get the error codes from your Jeep's computer with an first generation OBD scan tool - there may be another issue totally unrelated to the fuel pump.

You do understand that a '94 is really getting pretty old, right? After twenty years, it owes nobody anything. The Jeep's computer may be borderline dying... and you may not be able to get another GOOD computer to replace it. After twenty years, even new-old-stock computers off the shelf are pretty unlikely to work. Your Jeep may have driven its last miles - it's sad, but they DO have a much more finite life than the older (pre-1987) vehicles.

Yes it is possible you have low fuel pressure.
You check it with a gauge at the rail for the fuel injectors.

HELLO FRIEND .

WELL SOUND LIKE YOUR FUEL PUMP GOING OUT . WHEN PUMP IS COLD IT IS WORKING KIND OF FINE , BUT AS SOON AS GETS WARM , THE FUEL PRESSURE IS DROPS . CHANGE PUMP , IF YOU DONT HAVE IN OFF MONEY AT THE MOMENT >> KEEP FUEL LEVEL ABOVE HALF TANK , FUEL WILL KEEP PUMP COOL. GOOD LUCK !!

yes, are you sure that you did not just run out of gas, because the gage was not working? it sounds like they may have not gotten the fuel pump module back in the tank properly that would explain the no fuel gage, also when they had the pump out they may have damaged the wiring to the pump that could cause it to fail.

Hi, it sounds like you dont have any power to the fuel pump or the sending unit, turn the key to the "on" or run position and listen to see if you hear a humming noise. if you do not this means the fuel pump is not working, first check the fuses for the fuel pump. this should be under the hood in the fuse compartment. the battery guage doesnt work because the car is not running and charging the battery and will go up when the car starts. If the fuse is not blown you may have to replace the fuel pump.

bad e.c.m., these vehicles are known for this problem, just replaced e.c.m. on one recently for same problems.

Disconnect and replace fuel filter.With filter disconnected have someone momentarily turn key to on position to see is fuel pump is working.Make sure you have lots of rags,a drain pan and safety goggles on

check the fuel pump
