When the gauge pegs with the key on (top of its range) that means you have an open circuit (broken electrical path from the sender).

First, unhook the wire from the sender and test for continuity through the sender and ground (with a multimeter) - no continuity means sender is bad (open circuit within it).

You can also then ground the removed sender signal wire to verify the gauge is working or that you do not have a short to ground somewhere else between the sender and the gauge - grounded sender wire will peg the gauge a zero. If you remove the wire from the sender and do not ground the wire end, and the gauge does not go to the top of the range, you have a short to ground in the wire someplace between the wire end and the gauge.
