Are you looking for the fuel pump voltage?It should have battery voltage to the pump while cranking the engine. Do you have multi port or throttle body injection?

The pressure is way low try smacking the center of the gas tank with the palm of your hand while someone is cranking it. See if it starts or the pressure goes up?

I thought 40--47 psi was about right for fuel pressure. I used to have an 88 celeb 2.8L, it was mfi. I just thought the person might want to know the correct pressure. Have a good day.
