My friend most of the latest car come's across such problem so it's not the ground wiring problem it's the problem with the fuel gauge unit fitted inside the fuel tank it's time to get replaced it one thing is for sure that part is costly b'cause the fuel gauge is combination of  2 part's the fuel supply pumping motor unit & fuel level indicating gauge unit for such problem see for your nearest FORD authorised service centre across near by so till then drive safe have happy motoring so see you soon my friend..... !

My oil and gas gauge on my truck jump .... gas gauge works fine till i get to about half a tank then it starts jumping.. oil gauge jumps from the time i start my car and regulates but when i slow down or...


You probably have a bad sending unit for the fuel level in the tank. this would cause the gauge to be erratic when the level is below 1/2 tank and the float is moving around much more than when full. The oil pressure gauge problem could be caused buy a loose wire connection or a faulty sending unit.

I have a 95 F250 which periodically shuts off when using the front fuel tank when ½ full or under. The vehicle also seems to siphon fuel to the rear fuel tank while parked on various occasions. I am...


the fuel pump in the front tank could be over heating causing it to shut down for a short period of time. gas in the tank acually works like a coolant for tank mounted pumps so less gas = more heat

Fuel gauge is erratic. Moves between 1/4 and full


You may have a faulty fuel sending unit and the bad news is, that unit is in the fuel tank. GM has had a problem with these units and many times this has been the fix. Go to Walmart and buy 2 or 3 bottles of Techron. It is an additive for your fuel tank. It has cleaning agents that help remove the sulpher deposits which were corroding some of the fuel sending units in the tank. Run a few tankfulls of this thru your SUV. If your Equinox is out of warranty I would try this before anything.

Ford thunderbird fuel gauge stays on full


More than likely it is the sending unit inside the fuel tank. You will need to remove the fuel tank and take the sending unit out of the tank and replace it.

When replaced the fuel send unit the fuel gage sits on empty


Try grounding the gauge wire at the tank. If the gauge and wiring are good the gauge will go way past full when you do this.

Fuel gauge not working all the time.


This is a normal concern.
The instrument cluster uses 4 different operating modes to calculate the fuel level:
Anti-slosh (default mode)
Key OFF fueling
Key ON fueling
Recovery
After a fuel fill up, the time for the fuel gauge to move from empty (E) to full (F) ranges from 2 seconds to 55 minutes depending on which operating mode the fuel gauge is in.
The default fuel gauge mode is called the anti-slosh mode. To prevent fuel gauge changes from fuel slosh (gauge instability due to changes in fuel sender readings caused by fuel moving around in the tank), the fuel gauge takes approximately 55 minutes to go from empty (E) to full (F).
The key OFF fueling mode (2 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The key must be in the OFF position throughout the entire refueling of the vehicle.
At least 15% of the vehicle's fuel capacity must be added to the fuel tank.
The instrument cluster must receive a valid key ON fuel sender reading within 1 second of the key being put into the RUN position. The key ON sample readings are considered valid if the fuel sender reading is between 15 ohms ± 2 ohms and 160 ohms ± 4 ohms.
If these conditions are not met, the fuel gauge stays in the anti-slosh mode, which results in a slow to read full (F) event.
The key ON fueling mode (approximately 90 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The transmission is in PARK (P).
The key is in the RUN position.
At least 15% of the vehicle's fuel capacity must be added to the fuel tank.
In key ON fueling mode, a 30-second timer activates after the transmission is put into the PARK (P) position (automatic transmissions). When the 30-second time has elapsed and at least 15% of the vehicle's fuel capacity has been added, the fuel gauge response time is 90 seconds to read from empty (E) to full (F). When the transmission is shifted out of PARK (P), the fuel gauge strategy reverts to the anti-slosh mode. The key on refueling mode prevents slow to read full events from happening if the customer refuels the vehicle with the key in the RUN position.
Recovery mode is incorporated into the instrument cluster strategy to recover from a missing fuel level input during a refueling event. Missing fuel level inputs result from intermittent opens in the fuel sender or its circuits. Recovery mode (empty [E] to full [F] approximately 20 minutes) is initiated when the following 2 conditions are met:
The instrument cluster is in the anti-slosh (default) mode.
The actual fuel level in the tank is greater than what is being displayed by the fuel gauge

F 350 is having problems with fuel


sounds like you have a problem with the sending unit in the front tank. The pickup may have broken off only allowing the top half of the fuel in the tank to be used. Chances are you will need to drop the tank and check out the sending unit. I would also repair the rear tank, parts are cheap and it is very nice to have a redundant fuel system.
