Preliminary Information
These tests will determine whether the fuel system can supply adequate volume of fuel at the desired pressure to operate the engine under full load conditions. The test is done at four points in the system to isolate and identify the problem component:
fuel pump,
fuel filter, fuel injectors/rail, or
fuel supply line.
