System Inspection
■ Fuel pressure test - High pressure pump performance inspection

Check "Current Data" about fuel pressure with GDS.

Fig.1) Engine Idle after Warm Up & Approx. 2000rpm

A: Engine Idle after Warm Up(Approx. 4000 kPa = Approx. 40bar)

B: Approx. 2000rpm(Approx. 4000 kPa = Approx. 40bar)

Fig.2) When engine rapid acceleration

A: Approx. 12124 kPa = Approx. 121bar

■ Check the fuel filter for blockage

Remove the fuel pump and check filter debris and clogging of the fuel supply line.

■ Check the fuel level

If you run out of fuel significantly on ramp, it may be a factor of degradation of the fuel pressure.

■ Check low-pressure fuel supply line leakage and blockage.

Low-pressure fuel supply line damage and blockage can be a factor of the fuel pressure drop.
