Why doesn't the oil gauge pointer move when you step on the gas pedal?

Why doesn't the oil gauge pointer move when you step on the gas pedal? The reason why the barometer pointer does not move is:

1. There is something wrong with the oil slick: go to the repair shop to connect the two lines of the oil slick, and check the wiring and instrument panel. If it still doesn't move;

2. There is something wrong with the circuit of the fuel gauge: after removing the instrument, add a needle with a multimeter to find the circuit corresponding to the fuel gauge on the instrument for testing. Under the cover of modern automobile dashboard, various indicator lights or warning lights are made, such as coolant level warning light, fuel quantity warning light, washer level indicator light, charging indicator light, far and near light change indicator light, transmission gear indicator light, brake anti-lock braking system (ABS) indicator light, driving force control indicator light, airbag (SRS) warning light, etc.
