Fuel pump power
I have a 95 gmc sierra. I replaced the oil sending
unit and now I am not getting adequate power to
the fuel pump. The pump comes on when I
connect it directly to the battery? Any
did you check the fuel pump relay ?

Yes, I even replaced the relay. All this happened after I changed the oil sending unit
