"cold control pressure will be equal to system pressure given the system pressure cannot be reduced through the control pressure regulating function."
- Bob Kontak -
Actually, the system pressure is not affected by the control pressure, i.e. the control
pressure affects the quantity of fuel delivered thru the injectors. The greater the
control pressure, the less will be the fuel delivered.
To eliminate fuel as an issue, try spraying carb cleaner into the intake and see if
the engine will continue to run. If so, then make sure the cold control pressure
is about 20-30 psi and the warm is 50-60 psi with the system pressure about 70 psi.
Make sure the injectors are not sticking or not fully opening.
