Testing the fuel gage requires accessing the harness from the fuel pump and grounding the yellow / white wire with 160 ohms resistance this should cause the gage to read full, and with the circuit open you should have the gage reading empty. If the gage works in this order then the likely failure is the sending unit in the tank , and will require replacement.

Also my gas guage is stuck on full. it goes to empty when I turn ignition swith to off.do I need a new guage ?


It could be the gauge or the sender, in the fuel tank, or the fuse to the sender. On some Hondas there's a voltage regulator, in the gauge assembly, holding fuel gauge and some others to 8V.

It is the sending unit, usually the veryable resister and arm. Remove and replace sending unit. It is , unfortunately, located inside of the fuel tank. To confirm gage operation reverse wiring to the guage and it will reverse the guage, confirming tha the gauge.is ok.

No issues with the fuel guage that I know of , but you can follow the basic troubleshooting guidelines. Starting with the wiring disconnect at the fuel tank for a bad connector or bad connection. Only other connection would be up to the instrument cluster in the vehicle. Only replaceable items would be the guage or the sending unit in the fuel tank. You can disconnect the return line circuit or connector at the at the gas tank and jump a wire to the ground the that feeds the gauge and see if the guage moves, but don't and i repeat don't hold to long because the guage will go over hard over and could damage the guage. If the guage moved and I would suspect a bad float on the sending unit or a bad sending unit, either case the fuel pump assy would have to come out for repairs.

Fuel guage not working


I would guess that not many would do this as there is requirement for them to be both the same to balance out . GM had a problem for a while when the supplier of the gauges could not match the sender units and the gauges generally didn't work well. The real answer is to go to a wreckers that specialises in you make of car and get the dash unit to replace the damaged unit.

2007 F350 4x4 regular cab V10 gas guage quit working I had the sending unit and fuel pump changed the fuel guage went to 1/4 and sat there. Any tips? Fuel guage wont work.


I'm assuming this has dual tanks, do you know if it is not working on both tanks ?
Most people would check the circuit for the gauge at the tank. The sending unit grounds the gauge on the dash.

One of three things. Bad fuse, loose wire, bad gauge, or bad sending unit (located inside of fuel tank)

Your problem is fuel gauge is hanging up on the fuel pump. The slide bar/fuel sender is located inside the fuel tank alongside the fuel pump. Today I removed my fuel tank and replaced the pick up strainer on my fuel pump and previously my fuel gauge didn't work, but all I needed to do was slightly bend the slide mechanism and my fuel reading read correctly on my gauge. Previous to that I showed no reading on the dash meter.
