If you have replaced the switch itself, check the connection leading to the tank. if there is no loose wires or connectors then chances are that either there is a a bad connector to the float inside the tank, or the float itself is faulty. also if you flip the switch and the gauge still shows no change the it is the gauge it self that needs replacing because the odds of both flo9ats being faulty is very slim to none

Gas gauge won't work and it has a full tank of gas. Is there a fuse I can change.


There might be but it is unlikely a fuel gauge is fused alone; usually if it is a fuse other things will stop working too but I suggest you are guided in this matter by your car handbook.

Problem is probably wiring and in particular the grounding of the fuel tank sender unit. It could be a faulty sender but they are usually quite reliable.

Test by disconnecting the wire from the sender unit at the fuel tank and short to a good ground and the gauge should read full. If the gauge wire is in a block with other wires it will be necessary to positively identify the gauge wire before testing.
If the gauge reads refit the wire and duplicate the ground wire to a known good ground. If the gauge still reads the fault is a bad ground to the tank sender unit and if it doesn't the sender unit itself is probably faulty.

If grounding the gauge wire does not produce a reading the fault is the wiring to the tank, the supply to the gauge or a problem with the gauge itself.

I have Nissan patrol super safari mod.2005, problem with fuel gauge main tank showing maximum spare tank minimum please help


if you have 2 fuel gauges working of a tank switch there may be some resistance in the circuit of the second circuit that increases the reading of the gauge. Personally I have the tanks balanced out with a levelling hose between them the the gauge reads the capacity left in the tanks IE full-- both tanks-- full, 1/2 both tanks 1/2 With the way you have it set up then if one gauge is faulty and shows full when it is empty you can find yourself in a spot of bother when you need the other tank

Fuel gauge not working


One thing you should remember, always disconnect the power when playing with electricity, no matter what the voltage is, you can cause spikes and shorts all of which fries circuits and resistors, you need to get a very good manual with the resistances and voltages for every thing including your BCM

hi it can really only be two things, first is the fuel sender on the pump inside the tank it could be stuffed or sticking causing a false reading, second it can also be a faulty fuel gauge on the dash.

My f350 1997 will not run on the rear tank . how do i go about finding what the problem is?


well, first, to find out if its the in tank fuel pump or the tank selector valve, the cheapest and probable easiest thing to do is find the selector valve under the truck and switch the incoming fuel lines. front tank to rear tank inlet, and vice versa. If the truck still doesnt run, you either have an electrical delivery problem to the in tank fuel pump or a bad fuel pump. If after switching the lines, it does run, then you need a new selector valve

1992 f 159 dual tanks fuel guage not working


You will need to remove the wire for the sending unit on the tank and ground it to the frame with your selector switched to the tank you are working on and the key on. If gauge comes up to full then the sending unit is bad and gauge is good. Repeat process on other tank. The fuel tank switching valve on the frame also switches the wiring signal from either tank for the gauge. If no change with first test you will want to check the valve.

Gas gauge for 1983 nissan truck died


it is unlikely to be the fuel gauge, look instead to the sending unit. a wire probably is loose or corroded, if you know about how much fuel you should have, then remove the negative cable from the battery and do a ohms test on the sending unit. (low ohms w/ full tank= good, high ohms w/ low fuel= good). DO NOT attempt this with the battery connected as it could FRY your meter or risk fire.
