Question about 1996 Dodge Neon
48 PSI (Pounds per Square Inch)
Position the ignition switch and the A/C system in the off position. Install a fuel pressure gauge to the vehicles fuel rail service valve. Confirm that no leaks are present, and place the ignition switch in the run position and utilize a scan tool to energize the fuel pump. This will bring the system to a stabilized fuel pressure that can be visually verified on the gauge.
Black smoke is raw fuel, it's not being ignited, pull the spark plugs and inspect, if any black tiped electrodes that cylinder isn't firing,(spark plug, spark plug wire, coil, ignition modular not working properly, while the plugs are out perform a compression test, you need 80 psi in each cylinder to fire the fuel
