Wiring to Fuel Gage Sending unit

To troubleshoot, I need year--make--model, vehicle sold in the US.
I'd check the coolant temp sensor and wiring circuits. The same thing for fuel gage sending unit. Sometimes for the fuel gage sending unit, I get a couple of resistors one represents empty, the other represents full. If the gage reacts properly then the problem should be the sending unit in the gas tank.

Get the Body Control Unit BC1 Replaced..

Could be the gauge on the dash or the sending unit in the tank.

YOU HAVE FAULTY FUEL LEVEL SENDING UNIT ON FUEL PUMP ASSEMBLY OR LOOSE GROUND WIRE TO FUEL LEVEL SENDING UNIT CHECK WIRING HARNESS GOING INTO FUEL TANK.COULD HAVE SHORT BROKN WIRE IN WIRE HARNESS TO PUMP ASSEMBLY.

float in tank could be stuck or you have a faulty guage.
Check all your wiring!
Hope this helps, please let me know

Find the wires that run to your fuel gage. Hook one wire to one side of a "D" cell battery and the other wire to the other end of the battery. Your fuel gage should peg itself. If so the gage is good. That will tell you that more than likely the sending unit in the fuel tank is bad, If that is the case you will need to drop the fuel tank to remove the sending unit.

It is more likely to be at the fuel tank end of the system as the fuel level float is the consantly moving part and likely to become worn and give erratic readings. Replacing the sending unit should fix the problem. Also check for a loose connection in the wiring loom near the sending unit.

The first thing I would check is the wiring to the oil pressure sending unit. It is most likely located in the oil filter mount or somewhere in that area. Chances are, the small wiring harness may have been bumped loose or cracked recently when the oil was changed. It all looks well with the wiring, consider changing the sending unit. Hope this helps!

I need to know if the other gauges are accurate. There is a voltage regulator mounted on the back side of the dash that can go bad and often does, that will make the other gauges inaccurate also.

You have one of two possible things that are not working. The sending unit in the tank may be bad, or the gage in the dash is not working. Use a "C" cell battery and hook the wires to the gage in the dash to the battery ends. If the gage moves the guage is good. If that is the result then you will need to replace the sending unit in the fuel tank. That will require removing (dropping) the fuel tank to gain access to the sending unit.
