Sending Unit issue

Hi guys,
im still fixing the odd thing on my truck and today it was that my fuel level was WAY over full, naturally I went and checked and it has a new fuel pump and sender in it. So I redid the wiring, and still nothing.
I checked the two prongs Purple wire and Black and White wire from the new sender. It reads OL on my multimeter.
Does that mean that the sending unit is bad? The truck did sit almost a year with barely any gas in it.
No I’m not driving the truck with those connections, and yes I’m buying some tomorrow.
Thanks for any help

Yes, OL from the sending unit is no good at all
The ohms from the sender wire to pump ground should be roughly 15 ohms empty and 180 ohms full
