I have a 2001 Aurora with the 4.0 V8 and one day, right after filling up my tank, the gas gauge went straight to "empty" and stayed there. I took it to GM and they said my "fuel sending unit" had gone out, along with whatever sensor it has on it. They replaced both in about 4 hours and 450$ and it fixed the problem. Still works fine today over 2 years later.
Its probably the float in the gas tank that tells how much fuel is left in the tank... its sticking.
More than likely the fuel gauge sending unit located in the fuel tank is faulty.
The way to test the gauge is to unhook the wires to the sender and the gauge should read empty. Now, ground the sensor wire and the gauge should go all the way past the full level. If this happens your wiring and gauge are fine.
this problem could be caused by one or more of three things 1 The fuel sending unit is bad. this is a float connected to a variable resistance module that senses the fuel in the tank. To replace these you have to drop the fuel tank. 2 the gauge is bad. this is not usually a common occurance but it does happen. 3 the most common problem is in the wiring between the tank and the gauge. Use an ohm meter to make sure your connections are good.
No, the Aurora was made by Oldsmobile, which was discontinued by General Motors.
The fuel pump may be fine but the sending unit may not be. The sending unit is probably the most common cause of fuel gauge failure.
Depends on the car. Most should drop to empty when the ignition is off but some cars stay in the same position, they are rare though. (Toyota crown, Isuzu panther)
As my understanding is, the failure of the gauge is a result of the float in the tank getting a hole in it resulting in it filling full of gas and..well, not floating (grin). Pretty simple, drop the tank, remove the float, fix or replace the float and reinstall. If you have replaced the fuel pump, float (the entire unit basically) and it still has the same problem, and Upon start-up it goes to past full and the goes down to past empty, it could be an electrical problem between the tank and the gauge. You needs to check your fuses. The 1991 to 1994 models have a 15 amp fuse in location # 17 for the fuel gauge
PERHAPS THE PROBLEM LIES SOMEPLACE ELSE. IT MAY BE THE GAUGE ITSELF OR A WIRING PROBLEM.
Assuming you mean gallons of gasoline, the fuel gauge may not be accurate. It may read empty but in fact it may be still half full.
I recently had a simliar problem on my 1998 Aurora. I switched out the motor and still no go....ummm. I checked the fuse and it was blown. I recall starting the wipers when it was covered in ice and that's when the problem started. Also check out the site below it's totally dedicated to Auroras http://aurorah.proboards47.com/index.cgi
You can, but you still have a cooling problem that needs rectification.
