Need some help from anyone who has installed one of these. My fuel gauge reads empty no matter how much fuel is in the tank, the "test" function shows 0.2 ohms I have a ground running from the box to a stud on the sending unit and the box to stock harness connection. The stock harness has continuity so no issues there, all connections are good. Using a superpumper assembly if that matters

Try going to settings and set to gm90 sensor type. You can also probe the sending wire with a multimeter should read 90ohms if you have a full tank and if the sending unit is working correctly.

If you have throughly have checked all the wiring, the only other thing left to do is to drop the tank to cycle the sensor by hand and see if that will do anything.
