It relays bad info to the gauge. If you have a GM, it is probably what is wrong.
NO it will not.
yes
The fuel pump pressure sensor monitors the fuel pressure of the vehicle.
Gas sensor? Not sure what you mean, could it be a Fuel gauge sensor? Oxygen sensor? Fuel pressure regulator?
Bad fuel pressure regulator, Map. sensor not working or the vacuum line is bad or off of the sensor. You did not say what year it is.
There is no fuel pressure sensor.
The fuel pump pressure sensor monitors the fuel pressure of the vehicle.
mass air sensor or purge valve sensor could be a bad fuel pressure regulator
A fuel tank pressure sensor is a device used to measure the pressure in a fuel tank.
fuel tank pressure sensor or fuel tank level sensor? fuel tank level sensor is attached to the fuel sending unit, fuel tank pressure sensor is on top of the fuel tank.
Assuming you mean "fuel pressure regulator", year and engine size info we need to know, it matters.
where is fuel tank pressure sensor
