I have a 2005 Malibu V6 LS. Whenever I fill the tank with fuel(completely full) the engine light comes on and stays on for a couple of days. This causes problems with my remote starter - it doesn't work...

your car has a fuel level sensor on the fuel pump which is in the gas tank that is going bad this makes your engine light come on also makes your gas gauge read faulty, I think you can buy the fuel level sensor seperate from the fuel pump but i am not for sure my wifes car does the same thing i just havent got around to fixing it yet but when i do i will repost and et you know.

I have a 2004 pontiac montana. for about two years the fuel guage would fold over and read 125 degrees when the tank is full. it woulld stay there until tank was empty and the needle would drop to empty,...

It could be a bad fuel gauge in the dash unit, but....
Usually it's "The bad".
The fuel level sending wipe arm and windings on the fuel sender wear and send erratic readings.The only cure is a replacement fuel gauge sender.
The check engine light should not be related to the erratic fuel readings.
"The good".
If you have over 200,000kms or 120,000 miles on your van you need a new fuel pump anyway,so have a complete assembly put in which will have a new fuel sender on it.

Fuel gauge

It is not uncommon for GM fuel gauges to bounce up and down while the vehicle is moving. Especially on these older ones. Replacing the gauge or level sensor in the tank would only be a waste of money. It wont be the gauge though to answere your question.

How to replace the fuel sensor on a 2001 buick century.

If you mean the fuel level sender for the gauge it is part of the fuel pump module inside of the fuel tank. If you mean the fuel tank pressure sensor for the EVAP emission system it is located on top of the fuel pump module on the outside/top of the tank. If you have an erratic fuel gauge then the sender is most likely at fault. Some are serviced seperately but some are sold only as part of the pump. If you have to remove the tank and pump to replace the sender and have close to 100k on the odometer then I would STRONGLY suggest replacing the fuel pump at that time.

After filling my fuel tank, gauge does not go to takes a few days or hours for gauge to read full

There is a TSB on high sulfur fuel usage, and how it impacts the fuel level resistance.
If you change fuel, it might start working again. The TSB is : ERRATIC FUEL GAUGE OPERATION TSB 08-2-9

Publication Date: January 22, 2008
FORD: 2004-2008 F-150
LINCOLN: 2006-2008 Mark LT

Some 2004-2008 F-150 and 2006-2008 Mark LT vehicles, built before 12/3/2007, may exhibit erratic fuel gauge operation or illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0460 or P0463, and/or Instrument Cluster Module DTC B1201. This may be caused by sulfur contamination in the fuel causing an open or high resistance in the fuel level sender.

Follow the Service Procedure steps to correct the condition.


Install a new fuel level sender following the service procedure instruction sheet provided in the fuel sender kit.

Fuel gauge on 1993 Dodge Dakota V8

Definitely the gauge can be changed, provided the float in the fuel tank is OK, i.e. no leaks. This float connects to a potentiometer which records the current flowing thru it and displays it in the gauge. So before replacing the gauge measure the current and match that against the quantity of fuel in the tank...............sodeep
