The sender for the gauge ONLY drives the gauge, nothing else. Its probably just a loose connection. The area around the thermostat housing gets VERY hot, and the wiring and connectors get very brittle. The gauge sender is a single wire sensor. Just wiggle the connector around and I'll bet that it starts working.

it wont really matter which one you check first jsut figure out which isnt working . but check the one near the thermo. like he said that are gets hot fast.
