SOURCE: 96 grand cherokee fuel gauge shows empty but scanner shows 49%

sounds like a bad sending unit in the gas tank. While there you may as well replace the fuel pump too.

u don't need a diagram, just replace the gas tank fuel gauge sending unit, that is always the problem in your model.

You can try to clean the ground behind the instrument cluster to see if that helps but most likely the sending unit has gone bad in the gas tank.

SOURCE: fuel gauge issue

Hello. Before getting involved in real repairs, dump a bottle of fuel injector cleaner in your fuel tank. It may clean your sending units enough to get them working again. The chances of success are only about 50%, but the cost is very low. Redline, Chevron, and others make good fuel injection cleaner.

My fuel gauge hasn't been working for 10days now and I'm not sure what to look for. My first question, "is there a fuse for this problem or is there more to the problem"?


Probably more than a fuse if that is the only instrument that isn't working but you should check the fuse application chart in the vehicle handbook to be sure.

Usually a fuel gauge is tested and fault diagnosed by accessing the wiring at the fuel tank. A wiring diagram might be needed to identify which wire is to be tested. Simply shorting that wire to ground is the crude method of testing when a healthy gauge would usually read full scale. Using a sensor simulator is the correct method.

Getting a gauge reading by that method indicates either the fuel tank ground connection is bad or the fuel gauge unit in the fuel tank is faulty. If no reading was obtained the supply, the gauge, the wiring or the connections are faulty and it is time to investigate further.

I drive mercedes-benz 180 C-class, my fuel gauge reads 1/2 tank while my car refuse to start, i added fuel up to full tank and the car started. the following day my car stopped while the fuel gauge was...


there maybe a switch between the two tanks ,it must be replaced by a new one,to let the fuel on the other tank pass into the fuel pump.

See the dealer.

Temp gauge on 1994 mercedes c220 stopped working could it be fuse or what


Well, "Or What" would be the correct answer based on the choices given. Please read this article about fuses: Where's The Fuse?

You most likely have a problem with the Coolant Temperature Sensor. There are a couple of temp sensors. The one with the single green wire is the one for the gauge. If you disconnect the wire from the sensor, the gauge should read COLD. If you take a paper clip or small screwdriver and ground the green wire, the gauge should read HOT. If this works, then replace the sending unit. If the gauge stays COLD even when the wire is grounded, Then you need to check for an open circuit in the green wire between the sending unit (Sensor) and the insrument cluster. If the gauge reads HOT even with the sending unit unplugged, then check the green wire for a short to ground between the instrument cluster and the sending unit. If there is no problem with the wire - Not open or grounded, then the gauge itself is bad.

Fuel gauge is not detecting the correct level of petrol in tank. Suspect it may be a fuse, however the fuse diagram/ layout is missing... where can I download one? Mercedes Benz C180K 2004 model.


it is not a fuse. when a fuse burns, it never works again. look for broken/loose wires/connection around the fuel tank. usually, the problem is just a bad ground. the other solution is that maybe your fuel sending unit is faulty, test first, change if necessary
