GAS GAUGE TO WORK IMPROPERLY?

1997 Cadillac sts 4.6 If I hooked up the two black wires on my fuel pump wrong, would this cause the gas Gage to work improperly?

The gray wire is the power to the fuel pump and black goes to ground- dunno where the other black wire goes-no wiring diagram for the fuel sending unit-sorry

Double check the wiring from the connector to the fuel sending unit

Could it be a bad connection or something?? Is that what you think happened?

Dunno, you just have to backtrack your work if its working prior to replacing the pump-

The Gage dis work prior to replacing the pump. By the way thank you for your help. Does this seem like a wiring issue or maybe the float?

Open it up and recheck wiring and float resistances
