I have a 1996 Jeep Cherokee Sport 215K miles, my problem is that the fuel gauge it goes to low while having a full tank of gas, and the other problem is that feels like the transmission wants to run while stepping on the brake on a stop light? Can you please help me, Thanks

Sounds like your sending unit could be bad.

Check the Fuel Sending Unit in the fuel pump. Disconnect the wire to the sending unit, at the tank, and ground it to the car frame. Turn the key to on and see if the fuel gauge goes to Full. If it does the gauge and wire are good and the problem is in the sending unit. If it's still on E the gauge is bad or the wire is open.

Keep us updated.

The gas tank has nothing to do with the gauge. The fuel pump float could be stuck or the slide could have been bent when the pump was put back in. Also, the electrical connector could be unplugged or sot fully connected. This happens when someone pulls the wire instead of the plug.

does your jeep run rough? idle is real low? and when you are driving and push the gas hard it doesnt want to move? if so it is most likely the mass air flow sensor. i had to replace that 2 or 3 times on my 1999 jeep cherokee

There could be two problems here:
1. That buoy floating tank is not working properly
2. That the electrical system that fails to submit the dashboard.

Good luck... and remember rated this help.

Fuel level sending units are known to go bad on these.

change fuel filter sound like its stopping up .

This is going to sound a little back woods but try hitting your gas tank with a hammer or kicking it because your float that sends the amount to your gauge is stuck.

My guess is it's the fuel sending unit which is in the fuel tank itself. A lot of vehicles sending unit is part of the fuel pump, if you're a pretty good mechanic, you can run the tank down really low, lower the fuel tank and replace the sending unit.

Check VSS Vehicule Speed Sensor wire may be corroted, bad connection or faulty; if 2wd the adaptor is located on the extension housing of the transmission (left side)
if 4wd look on transfer case extension (left side)

Good luck
