Re: fuel gauge is not reading
To the right , i am assuming to the "full tank" reading. am i right?
if i am right, the wire from the gas tank is sending a full tank signal what ever the content of the tank.
meaning the wire is shorted to ground. or the sending unit is faulty. there is a short to ground reading between the sending unit.
you can test which one is faulty. remove the wire from the sending unit. observe the gauge. if the gauge would go to " empty" then the culprit is the sending unit. if it stays on " full tank", then the wire is faulty.
WARNING: GASOLINE IS EXTREMELY FLAMMABLE. BE VERY CAREFUL IN HANDLING NEAR THEM.

If gauge is pegged full then while driving goes empty then full then 1/2 it is the circuit board inside the fuel tank that has gone bad. to get the tank to register correctly then you must remove tank remove fuel pump module the float arm can be adjusted to read correct level
In a case like this, the culpret is most likely the fuel level sending unit, which is located on the fuel pump in the fuel tank. In most vehicles, the pump and the sending unit all come in one assembly, which means in order to get a correct reading on the gauge, you'll need to replace the fuel pump. And actually, considering the fact that you have to drop the fuel tank and remove the pump anyway, it's just good measure to change them as a set.
this almost always stems from a faulty fuel level sensor in the fuel tank. It's a part of the fuel pump, so you have to replace the whole thing at once in order to fix it. If you have around 100,000 miles on it, you're getting due for a pump anyways, so you may keep this in mind. Symptoms for the fuel sender, will be intermittent readings on the gas gauge, when it reads, it's correct, but when it doesn't, you get a low fuel message and the gauge goes to empty. This may have a tendency to do it when the fuel tank is within a certain level; but not at a fuller or lesser mark.
Sorry to say,but the fuel sending unit is the problem,the fuel tank will have to be lowered out of the vehicle to replace the unit.If the fuel sending unit is not available by itself you will have to replace the whole fuel pump assembley.
When gauge is pegged at full, usually means a bad ground. Check wires at fuel tank, wiggle around, maybe one came off. The bad news is it is hard to get to without removing the tank. Sometimes you can reach arm in and get to them. Also check body ground at read of van.
HI, the oil pressure sending unit may be malfunctioning at this point. this will cause erratic readings. if your oil level is proper and there are no apparent oil leaks, you will need to replace the oil pressure sending unit. this will fix the erratic oil pressure readings.
Concerning the gas gauge. this device also has a sending unit that sends the correct fuel level reading to the gas gaugevia wire transfer. this sending unit is located and attached to the fuel pump assembly inside the gas tank. replacing this device will fix this issue as well.
