run a jumper from the sender body (not the threaded stud) to a good ground & plug in the L female connector & run it & see if it starts to come up on the gauge.

All the Chryslers I've ever dealt with if the gauge moves when grounded, the gauge and circuit are good, the sender, not so... There's your answer, has to be the sensor or how it's mounted. The sensor is a variable path to ground dependent on temperature. No path, gauge doesn't work.

I can get you a cold reading from one on the bench later on today.

My one I had loose is showing open, I will see if I can grab another one. What I would do now is get it hot in your driveway (or go for a ride then come home) & clamp a jumper cable around the sender body & the other end of that cable to the batt neg post & see if it reads. That way you ain't gotta undo anything to see if it is a ground contact issue. it for sure is gonna have less than 2K ohms.

Why don't you install the sensor, warm the engine up, and then check the sensor resistance? The FSM uses the same tester (C-3826) for both the fuel gauge and the temperature gauge so the resistance ranges should be similar.

Thanks! ... Sure could read them warm but it would be nice to know what a good sende should read both cold and warm. .... That's a good thought BUT...what is "cold"? 75 degrees, 100 degrees, 120 degrees? I think the assumption that ambient temperature is the "cold" temperature in the design gauge temperature range may not be accurate. Likewise, what temperature would "warm" be? That's why I depend on the tester resistances to determine the status of a sensor.

I think if you think about the guage range, middle travel of the needle would be normal engine temp. So heat the sender to say 160* and it should ohm about 24.
