Intermittent oil gauge. Sometimes it works, and is fine, and sometimes it drops o zero and stays here. Is my sender going bad?

85 5 speed. Lots of work done, car is in good shape overall.

How's the wiring? Mine was pretty crispy and needed some new insulation.

Unlikely. More likely…

… wiring, or solder joints, or cluster connectors.

If I were to attempt to solve this problem by throwing parts at it, rather than diagnosis, the first part would be a new front main harness (starter,alternator,jump post.)

Diagnosis would start with a multimeter at the jump post connector pin for the sender or the fuse panel connector pin for the sender.

Of the dozens of “oil pressure” problems I’ve solved over the years, only one was through sender replacement.

luckily, my car is a fairly low mileage car that lived most of its life in the Northeast, garaged mostly and put away winters, and the plastic and wiring is still supple. I do think it could be pod related. I'll pull that and make sure the connection is good. I did a pod refresh a year ago and all was fine back there. but the oil gauge issue is a new one. I'll check the connections underneath too, before the pod.

Using the multimeter at the jump post, which pin is it? Also, which fuse panel slot for the sender?
TIA.
