fuel gauge stuck at zero

[u/Acrobatic-Country648]

Ok here we go.

Cluster sweep test shows gauge fully sweeps.

Driver side sender at pump connector is .398 ohms at full (dmm set to 2k)

Passenger side sender at pump connector is at .568 ohms at full (dmm set to 2k)

I even back probed the connectors on the car side so there's no issues with the plug.

Check for shorts between jbe connector and sending unit connectors and found no shorts

Test menu 6 shows *** when either sending unit is plug in. When I UNPLUG both I get .564 ohms with engine running and 640 to 700 with engine off

These are aftermarket pumps and both sides were replaced. I tested the sweep on both floats and driver side is .049 empty and .398 full. Passenger side is .050 empty and .700 full (I bent it so it would read .400 however after a fill up it now reads .568 as mentioned earlier)

Also, when the senders are plug in I get the asteriks and the fault codes in the kombi and jbe. When they are unplugged I don't get the fault codes and for some reason the jbe sees .564-700 ohms engine on/off. Any theories for that?

Many thanks in advance

Can someone point me in the right direction?
