How can I check the voltage of my fuel pump?
Check the voltage at the pump itself. Just because you’re getting juice from the circuit doesn’t mean that it’s getting to the pump itself, which makes it important to check the voltage there as well. Check out your vehicle’s service manual to find out where to check and the proper procedure for checking it.
What should the voltage be on a fuel tank sensor?
The voltage should never read zero or 5 V. Instead the reading should be somewhere in between those high and low points. The voltage should also change when the engine is first started. If you do find a fixed voltage reading between zero and 5 V you most likely have a defective sensor.
