The pressure must rise to approximately 430 kPa immediately.
If the rear fuel pressure is incorrect, replace the rear pressure regulator which is integrated in the fuel pump (FP).
If the rear fuel pressure is correct and the fuel pressure is incorrect in step 4, select the fault tracing path. See note below.
