turn the car on - where everything powers on but DO NOT START THE CAR.
this will initialize the fuel pump(s) and build pressure...leave the car on and watch the pressure drop. it should drops very slowly...not like 58..57...56....55..just going down fast.
if you watch the car drop 5psi-10psi..then you must be really bored cause it should take roughly 5 or so min?
