98 Honda Passport fuel gauge

My GF has a 1998 Honda Passport (rebadged Isuzu Rodeo) At 180,000 miles, the fuel pump died. The gas gauge had quit working prior to this, so I suggested she have the sending unit replaced when they did the fuel pump. The shop replaced the sending unit, but the gauge still reads empty all the time. The shop said there is a procedure that is required to reset the fuel gauge after replacement–a procedure which they apparently didn’t know. Does anyone know how this trick is done? Or is the shop full of BS?

Thanks in advance

I don’t know about any reset procedure, but I wonder if there is a problem with the wiring to the sensor.

Sounds bogus to me. If there is a reset procedure they would have access to it in their repair database.

I think there is another problem, either with the wiring or the gauge itself.
