If temp gauge is still working, then that rules out the voltage limiter.
If you can disconnect the sender wire from the sender, pull it up into the trunk and ground it with the ignition on. If the gauge begins to climb, that means the wire & gauge are still working.
Double check the ground strap for the sender. IIRC, these are just a metal strip that clips onto the metal fuel line coming out of the tank and clipping onto the line on the frame rail. Often, these rust away.
If that is still in good condition, then the only thing it could be would be the sender itself has pooped the bed. Usually the only repair is to replace.

Not True. If the float is heavy with gas then just it needs to be replaced. Had 2 gas gauges die and it was the float, not the sender . The replacement floats come in brass and plastic.

Any ideas 
Sure, (1) Pull the blue wire L connector off of the sender threaded nipple and with a long jumper connect it all the way up front to the batt neg post & see if the gas gauge swings over toward full (key on). (2) if the needle stays put seperate the connector behind the drivers kick panel and with the same jumper connected to batt neg post ground the sending unit wire in the upstream connector half & see if the needle now swings over to full ( www.mymopar.com has the color). if it will swing over in (1) then the problem is at the sender (the sender or its ground continuity path back to batt neg post). If it swings over in (2) but not in (1) then there is an open in the wire under the carpet from front to rear (3) plug the L blue wire connector back into to the threaded nipple on the sender and with the long jumper connected to the batt neg post (as before) take the other end & scrape it on the round sending unit flat metal base & see if the gauge now reads how much gas is in there (key on). (4) the short metal bracket with clips on each end that (electrically) connects the sender hard line nipple to the fuel line hard metal & as said twist both ends back & forth several times at the same time to check/restore continuity to that piece. (5) with your VOM see how many ohms there is between the sender threaded nipple and the flat round sender base & how much gas is in the tank which will affect that reading. Holler when you can
