2004 dodge durango fuel gauge not working. Put gas in, gauge will not go up on the gauge in the dash

Can not fix it got to replace the hole unit. Plus is illegal.

Possible cluster failure or body control module wiring faulty.

Faulty fuel sender, need to replace the fuel level sensor / fuel pump assem

Like most all vehicles, it could be the sending unit in the tank or the gauge on the dash. The sending unit would be disconnected and the circuit checked.

The float mechanism (or fuel level sender) on your fuel pump may be stuck or damaged. Attached is a digram of a typical fuel pump that is located inside the gas tank of your Dodge Durango.
You will need to remove your gas tank and pull out the old fuel pump to see if this is the problem. If you do this I would replace the fuel pump with a new one.

you need to check the fuel pressure at the reed valve with a fuel pressure gauge,you will need at least 55psi of fuel pressure to eliminate fuel as a possible cause.

WOO stop there is a major recall with the 05 durangos the check valves get stuck they are recalling the gas tanks on thousands of those car. that is a big fire hazard. Go to the dealer I garente ur vehcle is recalled u may have not gotten the notice in the mail yet. Please rate if this helps.

Here is a copy of the dealer recall notice.

2005 (HB) Dodge Durango
NOTE: This recall applies only to the above vehicles built from October 13, 2004
through November 30, 2004 (MDH101300 through 113023).
The fuel tank inlet check valve on about 18,900 of the above vehicles may stick in
the open position. This can cause fuel to spill out of the filler tube when the
vehicle is being refueled. Fuel in the presence of an ignition source can result in a
fire.
The fuel tank inlet check valve must be tested for proper operation. Vehicles with
a sticking check valve must have the fuel tank replaced.

UNPLUG THE SEATS

Put at least 3 gallons of fuel in your tank. Turn the key to the on position and let the fuel pump run for a little bit to refill the fuel lines. Attempt a restart.

The important thing now is, Do you really have gas in it? Check the fuel rail pressure and get that taken of, then check all grounds pertaining to the gauge assembly in the tank, and the dash grounding...accordianman
