My apologies, I left out parts and edited the post.
The gauge needle sits below E when ignition is off, then when ignition is on it jumps up to E then remains there.
-Tested the sending unit and it operates properly
-Check to verify and the truck does have around 1/2 tank of fuel in it
Next I'm going to replace the existing wires to see if that is the fix, then if that doesn't work then I have to assume the gauge itself is broken.
