Hello, I am new and have a quick question

When the fuel light comes on in the 1996 Dodge Ram v8 1500...How much gas does one have left? (reserve)
Thank You
BettyK

 

Well, guess no one knows [:-]

Thanks anyway...won't be back..I needed this answer today and now its too late...the person got strandedcause we had to take a guess

 

If you want to find out just take a GAS CAN with you for when you do run out.
It's never a good idea with a fuelie to run low on gas anyway. That's what cools the pump in the tank.

 

mine comes on at 1/8 tank (4 gal left), and takes 22 gal to fill it up.

 

Well, now that you've found out, tell us and we'll all know!

 

Don't ya just love it when someone's first post is demanding answers and they get pissed when they don't get it instantly

 

well she did wait a day.

there should be about 3 gallons left....

 

i know its not the same year but here is what the 2006 service manuals has to say. Don't think they would have much of a change in the approach.

OPERATION
The low fuel indicator gives an indication to the vehicle operator when the level of fuel in the fuel tank becomes low.
This indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster programming
and a hard wired input received by the cluster from the fuel level sending unit on the fuel pump module in the fuel
tank.
The low fuel indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster logic circuit, and
that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the
fused ignition switch output (run-start) circuit. Therefore, the LED will always be off when the ignition switch is in any
position except ON or START. The LED only illuminates when it is provided a path to ground by the instrument
cluster transistor. The instrument cluster will turn on the low fuel indicator for the following reasons:
² Bulb Test - Each time the ignition switch is turned to the ON position the low fuel indicator is illuminated for
about two seconds as a bulb test.
² Less Than 15 Percent Tank Full Input - The cluster provides a constant current source to the fuel level
sending unit and monitors a return input on a fuel level sense circuit. The resistance through the fuel level
sending unit increases as the fuel level falls and decreases as the fuel level rises causing changes in the
sense input voltage. Each time the fuel level sense input to the cluster indicates the fuel tank is about 15
percent or less for 10 consecutive seconds and the vehicle speed is zero, or for 60 consecutive seconds and
the vehicle speed is greater than zero, the fuel gauge needle is moved to about the one-sixteenth graduation
on the gauge scale, the low fuel indicator is illuminated, and a single chime tone is sounded. The low fuel
indicator remains illuminated until the fuel level sense input indicates that the fuel tank full is greater than
about 15 percent for 10 consecutive seconds and the vehicle speed is zero, or for 60 consecutive seconds and
the vehicle speed is greater than zero, or until the ignition switch is turned to the OFF position, whichever
occurs first. The chime tone feature will only repeat during the same ignition cycle if the low fuel indicator is
cycled off and then on again by the appropriate inputs from the fuel level sending unit.
² Less Than Empty Stop Input - Each time the cluster receives a fuel level sense input that indicates the fuel
level in the fuel tank is less than the Empty gauge needle stop position, the gauge needle is moved to the low
end of the gauge scale and the low fuel indicator is illuminated immediately. This input would indicate that the
fuel level sense input to the cluster is a short circuit.
² More Than Full Stop Input - Each time the cluster receives a fuel level sense input that indicates the fuel
level in the fuel tank is more than the Full gauge needle stop position, the gauge needle is moved to the low
end of the gauge scale and the low fuel indicator is illuminated immediately. This input would indicate that the
fuel level sense input to the cluster is an open circuit.
² Actuator Test - Each time the cluster is put through the actuator test, the low fuel indicator will be turned on,
then off again during the

 

i'm devastated that she won't be back [sm=smiley19.gif] [sm=smiley19.gif] [sm=smiley19.gif]
hey thats kind of cute, you can stretch the little pictures.... edit - never mind, it doesn't save it.
