I've had my autometer afr gauge hooked up for 3 to 4 years. And now when I turn the key it won't show the display. Could the gauge itself be bad? I've confirmed everything is wired correctly and the connections are clean.

Connect Pos/Neg. The gauge will go through its normal calibration cycle regardless of whether or not the O2 sensor is connected. If it's doesn't read w straight pos/Neg connection, I'd say gauge is bad.
