I have a 0-150psi 0.5v to 4.5 pressure transducer but i can't get to display correct info on oil or fuel pressure, when the car is not running it says it has -9 psi fuel pressure

these are the settings

Many sensors have a reading range of 0.5-4.5v

0 = 0psi
4.5v = X psi

Did you solve your issue?
Was that a Bosch 2 wire pressure sensor?
