Diagnostic Chart Part 2
5 - Fuel System Leakdown Test
The fuel system leakdown tests will determine if the fuel system is able to hold fuel pressure when the fuel pump is not operating. The system must hold
pressure to ensure that the fuel supply circuit (fuel lines, filter, pressure regulator, lines, and fuel rail) is full of fuel. When the fuel supply is completely
charged, fuel will be available at the injectors as soon as the ignition is turned On.
6 - Fuel Supply Pressure Tests
These tests will determine whether the fuel system, fuel pump, fuel filter and fuel pressure regulator can supply fuel at adequate pressure.
