When you get a reading of 54 PSI, that's the point where sometimes it will start, and sometimes it will not. Especially a Vortec 95 and 96. Takes 55-60 PSI to open the fuel-pressure reguator. Just a few PSI below, and it will not start. Very common problem in 95 and 96 GMs with the CPI injection system (Not TPI).
My 95 Astrovan with the 4.3 Vortec would not start at 55 PSI gauge. At 58 PSI, it started and ran perfect. Central Port Injection (AKA Tarantula).
